Abstract
The invention relates to a root box test device suitable for growing of plants. The root box test device comprises a cylindrical soil storage container and a cylindrical rhizosphere soil storage device, wherein the cylindrical rhizosphere soil storage device is positioned at the center of the cylindrical soil storage container and positioned on a lug boss; the cylindrical rhizosphere soil storage device comprises circular rings, support strips and nylon nets, which are combined to form a net-shaped cylinder with an upwards opening, the circular rings are positioned at two ends of the cylinder, the nylon nets are covered on the surfaces of the lower end and the outer side of the cylinder, and the lug boss is arranged at the center of the bottom surface of the cylindrical soil storage container. The cylindrical rhizosphere soil storage device is in interference fit with the cylindrical soil storage container through the lug boss and the circular rings. Soil is filled in a root box, and crops grow in the rhizosphere soil storage device. According to the root box test device, the problem that plant root systems only grow towards two directions during testing of the root box is solved, and the root systems radically grow towards the circumference so that the simulating test research result is accurate.
Description
Technical field
The invention belongs to the root case test unit field of plantation plant, be specifically related to a kind of root case test unit that is applicable to the little territory of research plant rhizosphere, can be used for modeling effort rhizosphere and non-rhizosphere soil.
Background technology
Rhizosphere refers to be subjected to the influence of root system of plant activity, is different from that part of little territory Tu Qu of the soil body in nature at physics, chemistry and biology.The scope of rhizosphere is very little, refers generally to apart within surperficial several millimeters of the root axle.It does not exist only in the root system surface to the former soil body in the radial direction, and is present in foundation portion to the longitudinal direction of the tip of a root.Because the research rhizosphere micro-region is relatively more difficult under field condition, so a lot of researchers adopt self-control root case modeling effort rhizosphere and non-rhizosphere soil, as: Yao Jianhua etc. are published in " Scientia Agricultura Sinica " 2010 the 43rd the 4th phases of volume, and He etc. are published in " Soil Biology; Biochemistry " the root case apparatus that adopts in the article of 2005 years the 37th volumes.The root casing is long-pending: length * wide * height=150mm * 140mm * 230mm.Nylon wire with 30 μ m is divided into 3 districts, and intermediate width is that the zone of 20mm is rhizosphere, and the both sides width is that the zone of 60mm is non-rhizosphere.The plant root growth space is: length * wide * height=150mm * 20mm * 230mm, therefore, it is radially grown and can only extend to 2 directions, do not meet under the field condition to around the true environment of elongation growth.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of root case test unit that is applicable to the plantation plant is provided, solve the problem that root system of plant is only grown to both direction in traditional root case test, can make root system to radially growth all around, meet the growth rhythm under the root system of plant natural conditions, thereby make the simulation test result of study more accurate.
Technical scheme of the present invention is as described below.
A kind of root case test unit that is applicable to the plantation plant, it comprises that a cylinder type holds soil container 1 and a cylinder type holds rhizosphere soil device 2, described cylinder type holds rhizosphere soil device 2 and is positioned at the center that cylinder type holds soil container 1, and place on the boss 6, described cylinder type holds rhizosphere soil device 2 and comprises annulus 3, support bar 4 and nylon wire 5, the three constitutes a right cylinder, its openend is (not covering nylon wire) upwards, wherein said annulus 3 is positioned at cylindrical two ends, by axially uniform support bar 4 as supporting and connecting as one, the aperture is that the nylon wire 5 of 30 μ m sticks on the right cylinder outside surface that is formed by support bar 4, and with the aperture be the nylon wire 5 of 30 μ m with right cylinder lower end back cover, the bottom center place that described cylinder type holds soil container 1 is provided with boss 6; Described cylinder type holds rhizosphere soil device 2 and holds soil container 1 with described cylinder type 3 interference are connected with annulus by boss 6.
The invention has the advantages that the problem that root system of plant is only grown to both direction in the test of root case that solved, can make root system to radially growth all around, meet the growth rhythm under the natural conditions, can obtain the pedotheque of plant rhizosphere and non-rhizosphere, thereby carry out researchs such as rhizosphere micro-region, the migration of non-rhizosphere soil nutrient and conversion, make the simulation test result of study more accurate.
More detailed technical scheme sees that " description of drawings " and " embodiment " is described.
The present invention is further described with implementing principle below in conjunction with accompanying drawing.
