Abstract

The utility model relates to a special cold-proof mulching film for a nursery garden in winter, which is mainly used for keeping nursery garden wood for proofing cold in timber forest and economic forest in the north of China in winter. The aim of the utility model is to overcome the defects of labor, time and force taking and seedling damage existing in the traditional old cold-proof method. The utility model is characterized in that the cold-proof mulching film is in a novel structure combined by a polyvinyl white film and a black film two layers. When the utility model is applied, the white film is arranged upwards, the black film is arranged downwards, and the circumference is mulched by soil.

Description

The nursery protection in winter is cold mulching specially used

The utility model is the monolayer polyethylene mulch film that a kind of two sides branch wears white black two kinds of different man of virtue and ability's looks.Be applicable to that mainly northern China covers reserved bed seedlings such as timber forest, economic forest, genseng winter, replace anti-dry frozen ground, guarantee the winter protection of surviving the winter.

In northern China, various evergreen needle saplings, people's seedling needs all will carry out ridging Gai Miao winter through staying bed to cultivate.The 72 of " forest zone, Heilongjiang Province Technical regulations for cultivation of tree seedlings " chapter 14 be regulation " the nursery seedling of surviving the winter should be kept properly, and all evergreenness needle saplings that survive the winter on former seedbed all will be carried out ridging Gai Miao, prevent cold " clearly.Ridging is covered the seedling technology and is leveraged to the present always.Like this, it is quite big with the soil amount to go up anti-dry frozen ground at the beginning of the winter, and it is difficult to fetch earth, and wastes time and energy, and the dry frozen ground of withdrawing a garrison of next spring for preventing to hinder seedling, still adopts " hand is taken off soil " at present, and not only labour intensity is big, and efficiency is low, also will pass through seedling-slowing stage, and influence is grown.In decades, people adopted several different methods to carry out Winterization Test, poured water, establish wooden camphor tree, little shed as employing, the lid straw screen or mat, and topped general mulch film, the result is eventually because of the cost height, and weak effect can not be applied or promote.

The purpose of this utility model is that protection in winter novel topped material of trembling with fear in a kind of nursery will be provided, and replaces anti-dry frozen ground.Its winter protection soil moisture conservation effectively is beneficial to the nursery stock winter dormancy, and material is easily got, and it is convenient to use, and raises the efficiency, and is anti-low-cost.

The purpose of this utility model is achieved in that to adopt generally makes base-material in order to the polyethylene of manufacturing mulch film, adds white and black additive respectively, makes blank, once pull into the double-colored composite membrane of individual layer with The tape casting, its thickness is 0.06MM, and the general 1600-1800MM of wide cut is white above, be black below, overlay film at the beginning of winter, firming all around, the next spring is removed film, roll gently, can use continuously three to four years.

The double-colored composite membrane of this individual layer is made easily, can be mass-produced; Nontoxic, nursery stock there is not any injury; Stuffy, help preserving soil moisture, greatly reduce nursery stock at the moisture transpiration in very long winter, keep its intrinsic vitality; On this film be white, to early spring sunlight reflex is arranged, do not absorb heat, be unlikely the seedling point of burning; Below this film be black, light tight, help the nursery stock Winter-Spring and finish dormancy.This film, is removed film and is reduced labour intensity easily multiple film, raises labour efficiency.This film is used for the genseng winter protection, can significantly reduce winter protection with the soil amount, dwindles the pavement width, improves land utilization rate.In a word, this film cost is low effective, easy and simple to handle, helps improving the seedling growth amount, is easy to promote.

The concrete structure of utility model provides (seeing accompanying drawing) by the following drawings

Accompanying drawing is the cold mulching specially used structural representation of nursery protection in winter.(1) is (white) above the mulch film among the figure, and (2) are below the mulch film or the back side (black), and (3) are ground film thickness 0.06MM among the figure; (4) be the mulch film width, according to seedbed width and height, general mulch film width can be decided to be 1600MM to 1800MM.Winter is during multiple film, the white one side upwards, black one faces down, and obturages with soil pressure is real all around.
