Description

本考案は育苗用の保護カバーに関し、特に樹木の苗木を育苗するのに好適な育苗用保護カバーする。 The present invention relates to a protective cover for raising seedlings, and is particularly suitable for raising seedlings of trees.

従来、杉や桧、松、クヌギ、桜、ケヤキ等の樹木の苗木作りは露地栽培が一般的であるため、植え付け作業は春または秋という季節に限定されていたが、最近では複数のポットが連結されて成る樹脂製の育苗用容器を使用することにより、育苗作業の効率化が図られると共に、年間を通して植え付け作業が可能となっている。 In the past, planting work was limited to the season of spring or autumn because saplings of trees such as cedar, cypress, pine, kunugi, cherry blossoms, and zelkova were generally cultivated in the open field, but recently, multiple pots have been used. By using the connected resin seedling raising containers, the efficiency of the seedling raising work is improved and the planting work is possible throughout the year.

また、従来の樹脂製の育苗用容器に代わる種々の育苗用容器も開示されている（例えば、特許文献１及び特許文献２参照。）。特許文献１に開示された育苗用容器は、縫い糸で縫製されたポリ乳酸布帛を用いた育苗用容器であって、縫い糸で縫製した縫製部分が任意に解舒可能であることを特徴とする。当該構成を備える特許文献１に係る育苗用容器によると、任意に育苗用容器が解舒可能であり、植物の根詰まりが少なく、成長を妨げない育苗用容器を得ることができる旨、記載されている。 Further, various seedling raising containers that replace the conventional resin seedling raising containers are also disclosed (see, for example, Patent Document 1 and Patent Document 2). The seedling raising container disclosed in Patent Document 1 is a seedling raising container using a polylactic acid cloth sewn with a sewing thread, and is characterized in that a sewn portion sewn with a sewing thread can be arbitrarily unwound. According to the seedling raising container according to Patent Document 1 having the said structure, it is described that the seedling raising container can be arbitrarily unwound, the root clogging of the plant is small, and the seedling raising container that does not hinder the growth can be obtained. ing.

また、特許文献２に開示された植物栽培用袋は、透液性を有すると共に、栽培植物の根の貫通を阻止し得る程度の微細な孔隙を有するシート状素材から袋状に形成されてなることを特徴とする。このようにして形成された特許文献２に係る植物栽培用袋内に土を充填して、植物を植え込み、且つこの植物栽培用袋を地面に埋設する。移植の際には、植物栽培用袋を取り出すのみでよく、根回し作業が不要となる旨、記載されている。 Further, the plant cultivation bag disclosed in Patent Document 2 is formed of a sheet-like material having liquid permeability and having fine pores capable of preventing the penetration of the roots of the cultivated plant. It is characterized by that. Soil is filled in the plant cultivation bag according to Patent Document 2 thus formed, a plant is planted, and the plant cultivation bag is buried in the ground. It is stated that when transplanting, it is only necessary to take out the plant cultivation bag, and no rooting work is required.

従来の複数のポットが連結されて成る樹脂製の育苗用容器を使用して育苗を行った場合、各ポット内で育苗された苗は不揃いに生長するため、育苗途中でポットから抜き取り、生長具合が揃った苗同士の入れ替え作業が必要となる。 When raising seedlings using a conventional resin seedling raising container made by connecting multiple pots, the seedlings raised in each pot grow irregularly, so the seedlings are removed from the pot during raising seedlings and the growth condition It is necessary to replace the seedlings that have all the seedlings.

しかし、ポット内で苗が生長して根が張ると、苗をポットから抜き取ることが非常に困難となる。また、抜き取りが困難となった苗を無理に抜き取ると、苗や根を傷めたり、根鉢が崩れたりするおそれがある。 However, when the seedlings grow and take root in the pot, it becomes very difficult to remove the seedlings from the pot. In addition, if the seedlings that are difficult to remove are forcibly removed, the seedlings and roots may be damaged or the root pot may collapse.

そこで、例えば特許文献１に係る育苗用容器によると、任意に育苗用容器を解舒することができるため、植物の根詰まりは少なくなるものと思料する。 Therefore, for example, according to the seedling raising container according to Patent Document 1, since the seedling raising container can be arbitrarily unwound, it is considered that the root clogging of the plant is reduced.

また、特許文献２に係る植物栽培用袋も、移植の際には植物を地面から植物栽培用袋ごと取り出すため、従来の樹脂製の育苗用容器を使用する場合と違って、移植の際に植物や根を傷めるおそれがない。 Further, in the plant cultivation bag according to Patent Document 2, since the plant is taken out from the ground together with the plant cultivation bag at the time of transplantation, unlike the case of using a conventional resin seedling raising container, at the time of transplantation. There is no risk of damaging plants or roots.

しかし、特許文献１に係る育苗用容器や特許文献２に係る植物栽培用袋は、これら育苗用容器内、植物栽培用袋内に培土を充填して播種、或いは小苗を移植した後、地面に埋設される。従って、樹木の苗木栽培においては、従来の露地栽培と代わるところがなく、植え付け作業の時期が限られる。 However, the seedling raising container according to Patent Document 1 and the plant cultivation bag according to Patent Document 2 are placed on the ground after filling the seedling raising container and the plant cultivation bag with soil and sowing or transplanting small seedlings. It will be buried. Therefore, in the cultivation of tree saplings, there is no substitute for the conventional open-field cultivation, and the time of planting work is limited.

また、特許文献１に係る育苗用容器及び特許文献２に係る植物栽培用袋は何れも地面に埋設して使用するものであるため、移植する場合にはそれぞれの容器（袋）の周囲の土を丁寧に掘る必要があり、非常に手間が掛かる。 Further, since the seedling raising container according to Patent Document 1 and the plant cultivation bag according to Patent Document 2 are both used by being buried in the ground, the soil around each container (bag) is used when transplanting. It is necessary to dig carefully, which is very time-consuming.

更に、地面に埋設して育苗するため、生長具合を揃えるための苗の植え替え作業を行うことも略不可能である。 Furthermore, since the seedlings are raised by burying them in the ground, it is almost impossible to replant the seedlings in order to adjust the growth condition.

そこで本願考案者は、上記の問題点に鑑み、複数のポットが連結されて成る樹脂製の育苗用容器を使用して効率的に育苗することができると共に、苗や根を傷めることなく容易に生育途中の苗の入れ替え作業ができる育苗用保護カバーを提供するべく鋭意検討を重ねた結果、本考案に至ったのである。 Therefore, in view of the above problems, the inventor of the present application can efficiently raise seedlings by using a resin seedling raising container in which a plurality of pots are connected, and can easily raise seedlings without damaging the seedlings or roots. As a result of diligent studies to provide a protective cover for raising seedlings that can replace seedlings during growth, the present invention was reached.

即ち、本考案は、育苗用容器のポット内に配設される育苗用保護カバーであって、略扇形状をなすシート状部材で構成され、前記シート状部材を筒状にして前記ポットに内設されることを特徴とする。 That is, the present invention is a seedling raising protective cover arranged in a pot of a seedling raising container, which is composed of a sheet-shaped member having a substantially fan shape, and the sheet-shaped member is made into a cylinder and inside the pot. It is characterized by being installed.

また、本考案の育苗用保護カバーにおいて、前記シート状部材が生分解性を有することを特徴とする。 Further, in the protective cover for raising seedlings of the present invention, the sheet-like member is characterized by having biodegradability.

更に、本考案の育苗用保護カバーにおいて、前記シート状部材がフィルム、織布、不織布、紙の何れかから成ることを特徴とする。 Further, in the protective cover for raising seedlings of the present invention, the sheet-like member is characterized by being made of any one of a film, a woven fabric, a non-woven fabric, and paper.

また、本考案の育苗用保護カバーにおいて、前記シート状部材に複数の貫通孔が形成されていることを特徴とする。 Further, the protective cover for raising seedlings of the present invention is characterized in that a plurality of through holes are formed in the sheet-shaped member.

本考案の育苗用保護カバーによると、複数のポットが連結されて成る樹脂製の育苗用容器を使用して効率的に育苗することができる。 According to the protective cover for raising seedlings of the present invention, seedlings can be raised efficiently by using a resin-made seedling raising container in which a plurality of pots are connected.

特に、各ポット内で生長した苗を移植する際、ポットと培土との間に本考案の育苗用保護カバーが介在しているため、ポットから容易に苗を抜き取ることができる。従って、育苗途中で生長具合が不揃いとなった際、苗や根を傷めることなく、苗の入れ替え作業を容易に行うことができる。 In particular, when transplanting seedlings grown in each pot, the seedlings can be easily removed from the pots because the protective cover for raising seedlings of the present invention is interposed between the pots and the soil. Therefore, when the growth condition becomes uneven during the seedling raising, the seedling replacement work can be easily performed without damaging the seedlings and roots.

また、ポットから苗を抜き取る際に、本考案の育苗用保護カバーによって根鉢が保護されているため、根鉢が崩れたり、根を傷めたりするおそれもない。 Further, when the seedlings are removed from the pot, the root pot is protected by the protective cover for raising seedlings of the present invention, so that there is no risk of the root pot collapsing or damaging the roots.

更に、通常の樹脂製の育苗用容器は黒いため、夏場はポット内が高温となるが、本考案の育苗用保護カバーが保水した状態で根鉢を保護しているため、ポットの冷却効果及び断熱効果が得られる。一方、冬場は本考案の育苗用保護カバーによる保温効果が得られる。 Furthermore, since the normal resin container for raising seedlings is black, the temperature inside the pot becomes high in the summer, but since the protective cover for raising seedlings of the present invention protects the root pot while retaining water, the cooling effect of the pot and A heat insulating effect can be obtained. On the other hand, in winter, the heat-retaining effect of the protective cover for raising seedlings of the present invention can be obtained.

また、ポットから抜き取った苗の根鉢が本考案の育苗用保護カバーによって保護されているため、出荷用に複数の苗を一纏めにする際も容易に荷造りが行えると共に、出荷後における根鉢の保護及び根鉢の乾燥を抑制することもできる。 In addition, since the root pot of seedlings taken out from the pot is protected by the protective cover for raising seedlings of the present invention, it is easy to pack multiple seedlings for shipping and the root pot after shipping. It can also protect and prevent the root pot from drying out.

更にまた、本考案の育苗用保護カバーは略扇形状をなすシート状部材で構成され、筒状にして使用されるものであって、両辺部が接着や縫着されていない。従って、育苗用容器が備える各ポットで生長した苗の根鉢から育苗用保護カバーを容易に剥ぎ取ることができるため、地面への移植後に根張りを邪魔することがなく、苗の活着が良好となる。 Furthermore, the protective cover for raising seedlings of the present invention is composed of a sheet-shaped member having a substantially fan shape, and is used in a tubular shape, and both sides thereof are not adhered or sewn. Therefore, since the protective cover for raising seedlings can be easily peeled off from the root pot of seedlings grown in each pot provided in the container for raising seedlings, the rooting is not hindered after transplanting to the ground, and the rooting of seedlings is good. Will be.

また、本考案の育苗用保護カバーにおいて、シート状部材が生分解性を有することによって、育苗用容器が備える各ポットで生長した苗の根に育苗用保護カバーを巻いたままの状態で地面に移植することができ、移植時における根の損傷や根鉢の崩れを防止することができると共に、移植作業の効率化を図ることができる。 Further, in the seedling raising protective cover of the present invention, since the sheet-like member has biodegradability, the seedling raising protective cover is placed on the ground with the seedling raising protective cover wrapped around the roots of the seedlings grown in each pot provided in the seedling raising container. It can be transplanted, it is possible to prevent root damage and collapse of the root pot at the time of transplantation, and it is possible to improve the efficiency of the transplanting work.

また、本考案の育苗用保護カバーにおいて、シート状部材がフィルム、織布、不織布、紙の何れかから成ることによって、従来の樹脂製の育苗用容器を使用しつつ低コストで移植が容易な苗を効率的に育苗することができる。 Further, in the protective cover for raising seedlings of the present invention, since the sheet-like member is made of any of film, woven fabric, non-woven fabric, and paper, it is easy to transplant at low cost while using a conventional container for raising seedlings made of resin. Seedlings can be raised efficiently.

更に、本考案の育苗用保護カバーにおいて、シート状部材に複数の貫通孔を形成することによって、育苗用保護カバーを巻いたままの状態で地面へ定植した場合であっても、貫通孔から根が外部へ張りだすことができ、植物の生長を妨げることがない。 Further, in the protective cover for raising seedlings of the present invention, by forming a plurality of through holes in the sheet-shaped member, even when the protective cover for raising seedlings is planted on the ground while being wound, the roots are formed from the through holes.

以下、本考案の育苗用保護カバーの実施形態について、図面に基づいて詳述する。図１（ａ）は、本考案の一実施形態に係る育苗用保護カバー１を示す平面図、同図（ｂ）は育苗用保護カバー１を筒状にした状態を示す斜視図である。図１に示すように、本実施形態に係る育苗用保護カバー１は、略扇形状をなすシート状部材２で構成されている。 Hereinafter, embodiments of the protective cover for raising seedlings of the present invention will be described in detail with reference to the drawings. FIG. 1A is a plan view showing a seedling raising protective cover 1 according to an embodiment of the present invention, and FIG. 1B is a perspective view showing a state in which the seedling raising protective cover 1 is tubular. As shown in FIG. 1, the seedling raising protective cover 1 according to the present embodiment is composed of a sheet-shaped member 2 having a substantially fan shape.

本実施形態に係る育苗用保護カバー１は、図１（ｂ）に示すように、シート状部材２に係る両辺部４、４を合わせて筒状にした状態で使用される。シート状部材２に係る両辺部４、４を合わせて筒状にすることによって、上側円弧５で上部開口５ａが形成され、下側円弧６で底部開口６ａが形成されることとなる。なお、両辺部４、４は接着や逢着、溶着等がされておらず、容易に展開可能な状態となっている。両辺部４、４を接着等しないことによって、直径の異なるポットにも容易に対応することができると共に、ポット内で生長した苗を移植する際、生長した苗の根鉢から育苗用保護カバーを容易に剥ぎ取ることができる。 As shown in FIG. 1 (b), the nursery protective cover 1 according to the present embodiment is used in a state in which both side portions 4 and 4 related to the sheet-shaped member 2 are combined into a tubular shape. By combining the side portions 4 and 4 of the sheet-shaped member 2 into a cylindrical shape, the upper arc 5 forms the upper opening 5a, and the lower arc 6 forms the bottom opening 6a. It should be noted that the side portions 4 and 4 are not adhered, welded, welded, etc., and are in a state where they can be easily deployed. By not adhering both sides 4 and 4, it is possible to easily handle pots with different diameters, and when transplanting seedlings grown in the pot, a protective cover for raising seedlings is attached from the root pot of the grown seedlings. It can be easily peeled off.

そして、本実施形態に係る育苗用保護カバー１は、図２に示すように、筒状にした状態で複数のポット１１が連結されて成る樹脂製の育苗用容器１０に係る各ポット１１内に配設される。各ポット１１内に筒状にした育苗用保護カバー１を配設し、上側円弧５で形成された上部開口５ａから培土を充填した後、播種或いは小苗が移植される。 Then, as shown in FIG. 2, the seedling raising protective cover 1 according to the present embodiment is placed in each pot 11 related to the resin seedling raising container 10 in which a plurality of pots 11 are connected in a cylindrical state. Arranged. A tubular protective cover 1 for raising seedlings is arranged in each pot 11, and after filling the soil from the upper opening 5a formed by the upper arc 5, sowing or seedlings are transplanted.

各ポット１１内で育苗された苗は、地面に定植されることとなる。ここで、各ポット１１内で育苗された苗の根は本実施形態に係る育苗用保護カバー１によって根巻きされたような状態となっている。更に、各ポット１１の内周面と培土との間にこの育苗用保護カバー１が介在した状態となっている。 The seedlings raised in each pot 11 will be planted on the ground. Here, the roots of the seedlings raised in each pot 11 are in a state of being wrapped by the seedling raising protective cover 1 according to the present embodiment. Further, the seedling raising protective cover 1 is interposed between the inner peripheral surface of each pot 11 and the soil.

複数のポット１１を備える育苗用容器１０を使用して複数の苗を一度に育苗する際、苗の生長にバラツキが生じる。例えば、育苗用容器１０におけるポット１１の位置によって苗の生長にバラツキが生じる場合、具体的には図３（ａ）に示すように、複数の育苗用容器１０において生長のよい苗２０と、生長が後れている苗２１が混在している場合、育苗用容器１０に係るポット１１内に育苗用保護カバー１が介在されているため、苗２０、２１を容易に抜き取ることができ、図３（ｂ）に示すように、苗２０と苗２１を入れ替えて生長具合を揃えることが可能となる。従って、成長のよい苗２０だけを纏めることができるため、生長が後れている苗２１の生長を待つことなく、早期に出荷することも可能となる。 When raising a plurality of seedlings at one time using the seedling raising container 10 provided with the plurality of pots 11, the growth of the seedlings varies. For example, when the growth of seedlings varies depending on the position of the pot 11 in the seedling raising container 10, specifically, as shown in FIG. 3A, the seedlings 20 having good growth and the seedlings growing in the plurality of seedling raising containers 10 When the seedlings 21 that are behind are mixed, the seedlings 20 and 21 can be easily pulled out because the seedling raising protective cover 1 is interposed in the pot 11 related to the seedling raising container 10. FIG. As shown in (b), the seedlings 20 and 21 can be exchanged to make the growth condition uniform. Therefore, since only the seedlings 20 having good growth can be collected, it is possible to ship the seedlings early without waiting for the growth of the seedlings 21 which are lagging behind.

以上のように、本実施形態に係る苗用保護カバー１によると、複数のポット１１が連結されて成る樹脂製の育苗用容器１０、１０ａを使用して効率的に育苗することができる。特に、各ポット１１、１１ａ内で生長した苗を移植する際、ポット１１、１１ａと培土との間に本実施形態に係る育苗用保護カバー１が介在しているため、ポット１１、１１ａから容易に苗を抜き取ることができる。従って、育苗途中で生長具合が不揃いとなった場合も際、苗や根を傷めることなく、苗の入れ替え作業を容易に行うことができる。 As described above, according to the seedling protective cover 1 according to the present embodiment, seedlings can be efficiently raised by using the resin seedling raising containers 10 and 10a in which a plurality of pots 11 are connected. In particular, when transplanting seedlings grown in the pots 11 and 11a, the protective cover 1 for raising seedlings according to the present embodiment is interposed between the pots 11 and 11a and the soil, so that the seedlings can be easily removed from the pots 11 and 11a. Seedlings can be extracted. Therefore, even when the growth condition becomes uneven during the seedling raising, the seedling replacement work can be easily performed without damaging the seedlings and roots.

また、ポット１１、１１ａから苗を抜き取る際に、本実施形態の育苗用保護カバー１によって根鉢が保護されているため、根鉢が崩れたり、根を傷めたりするおそれもない。 Further, since the root pot is protected by the seedling raising protective cover 1 of the present embodiment when the seedlings are taken out from the pots 11 and 11a, there is no possibility that the root pot will collapse or the roots will be damaged.

更に、抜き取った苗の根鉢が本実施形態の育苗用保護カバー１によって保護されているため、出荷用に複数の苗を一纏めにする際も容易に荷造りが行えると共に、出荷後も根鉢の保護及び乾燥の抑制を図ることもできる。 Further, since the root pot of the extracted seedling is protected by the seedling raising protective cover 1 of the present embodiment, it is possible to easily pack a plurality of seedlings for shipping and to use the root pot even after shipping. It is also possible to protect and suppress drying.

また更に、本実施形態の育苗用保護カバー１は根を保護すると共に培土を包んだ状態となっているため、ポット１１内において育苗用保護カバー１が断熱材の役割を果たす。従って、通常の樹脂製の育苗用容器は黒いため、夏場はポット１１内が高温となるが、本実施形態の育苗用保護カバー１が保水した状態で根鉢を保護しているため、ポット１１の冷却効果及び断熱効果が得られる。また、冬場には保温効果が得られ、これら時期に応じた冷却・断熱・保温効果が得られることによって、苗の生長を促進する効果が得られる。 Furthermore, since the seedling raising protective cover 1 of the present embodiment protects the roots and wraps the soil, the seedling raising protective cover 1 serves as a heat insulating material in the pot 11. Therefore, since the normal resin container for raising seedlings is black, the temperature inside the pot 11 becomes high in the summer, but since the protective cover 1 for raising seedlings of the present embodiment protects the root pot in a water-retaining state, the pot 11 Cooling effect and heat insulating effect can be obtained. In addition, a heat retaining effect is obtained in winter, and a cooling / heat insulating / heat retaining effect according to these seasons is obtained, so that an effect of promoting the growth of seedlings can be obtained.

また、本実施形態の育苗用保護カバー１を育苗用容器１０に係るポット１１内に配設することによって、培土の水分調整が容易となる。育苗用保護カバー１によって培土の保水性が良好となるため、必要以上の潅水が防止できると共に、肥料の流出も防止できる。 Further, by disposing the seedling raising protective cover 1 of the present embodiment in the pot 11 related to the seedling raising container 10, the water content of the hilling can be easily adjusted. Since the protective cover 1 for raising seedlings improves the water retention of the soil, it is possible to prevent unnecessary irrigation and prevent the outflow of fertilizer.

以上、本考案の一実施形態に係る育苗用保護カバー１について説明したが、本考案は上記の実施形態に限定されない。例えば、本考案の育苗用保護カバーは略扇形状をなすシート状部材で構成され、筒状にして使用されるものであって、両辺部が接着や縫着、溶着等されていない。従って、育苗用容器が備える各ポットで生長した苗の根鉢から育苗用保護カバーを容易に剥ぎ取ることができるため、地面への移植後に根張りを邪魔することがなく、苗の活着が良好となる。 Although the nursery protective cover 1 according to the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the protective cover for raising seedlings of the present invention is composed of a sheet-shaped member having a substantially fan shape, and is used in a tubular shape, and both sides thereof are not bonded, sewn, welded, or the like. Therefore, since the protective cover for raising seedlings can be easily peeled off from the root pot of seedlings grown in each pot provided in the container for raising seedlings, the rooting is not hindered after transplanting to the ground, and the rooting of seedlings is good. Will be.

しかし、本考案の育苗用保護カバーにおいて、育苗用保護カバーを構成するシート状部材が更に生分解性を有していてもよい。シート状部材が生分解性を有することによって、例えば図２に示すように、育苗用容器１０が備える各ポット１１で生長した苗の根に育苗用保護カバーを巻いたままの状態で地面に移植することができ、移植時における根の損傷や根鉢の崩れを防止することができると共に、移植作業の効率化を図ることができる。 However, in the seedling raising protective cover of the present invention, the sheet-shaped member constituting the seedling raising protective cover may have further biodegradability. Due to the biodegradability of the sheet-shaped member, for example, as shown in FIG. 2, the seedlings grown in the pots 11 provided in the seedling raising container 10 are transplanted to the ground with the seedling raising protective cover wrapped around the roots. It is possible to prevent damage to the roots and collapse of the root pot at the time of transplantation, and it is possible to improve the efficiency of the transplantation work.

また、本考案の育苗用保護カバーにおいて、育苗用保護カバーを構成するシート状部材がフィルム、織布、不織布、紙の何れかから成ることが好ましい。シート状部材がフィルム、織布、不織布、紙の何れかから成ることによって、従来の樹脂製の育苗用容器を使用しつつ低コストで移植が容易な苗を効率的に育苗することができる。 Further, in the protective cover for raising seedlings of the present invention, it is preferable that the sheet-shaped member constituting the protective cover for raising seedlings is made of any one of film, woven fabric, non-woven fabric and paper. Since the sheet-shaped member is made of any of film, woven fabric, non-woven fabric, and paper, it is possible to efficiently grow seedlings that are easy to transplant at low cost while using a conventional resin seedling raising container.

更に、本考案の育苗用保護カバーにおいて、育苗用保護カバーを構成するシート状部材には、複数の貫通孔が形成されていてもよい。図１に示した実施形態に係る育苗用保護カバー１には、辺部４に略並行な貫通孔３が複数形成されている。このような複数の貫通孔３を形成することによって、育苗用保護カバー１を巻いたままの状態で地面へ定植した場合であっても、貫通孔３から根が外部へ張りだすことができ、植物の生長を妨げることがない。なお、貫通孔３の形状や形成数は特に限定されず、育苗する植物の種類や育苗用容器が備えるポットのサイズに応じて適宜、選択される。 Further, in the seedling raising protective cover of the present invention, a plurality of through holes may be formed in the sheet-shaped member constituting the seedling raising protective cover. The seedling raising protective cover 1 according to the embodiment shown in FIG. 1 is formed with a plurality of substantially parallel through holes 3 in the side portions 4. By forming such a plurality of through holes 3, the roots can be projected from the through holes 3 to the outside even when the seedling raising protective cover 1 is planted on the ground in the rolled state. It does not hinder the growth of plants.
