[0013] Example 1

[0014] by Figure 1 to Figure 3 The structure of the present invention and its connection relationship are as follows:

[0015] A root box test device suitable for planting plants. It consists of a cylindrical soil storage container 1 and a cylindrical rhizosphere soil device 2, wherein the cylindrical rhizosphere soil device 2 (with a diameter of about 6mm) is located The center of the cylindrical soil storage container 1 is placed on the boss 6; the cylindrical rhizosphere soil device 2 includes a ring 3, a support bar 4 (perspex or PVC board material can be used) and a nylon mesh 5. The combination of the three forms a cylinder, the open end of which is upwards (not covered with nylon mesh), wherein the ring 3 is located at the two ends of the cylinder, supported by the axially evenly distributed support bars 4 and connected as A nylon net 5 with a diameter of 30 μm is pasted on the outer surface of the cylinder formed by the support bar 4, and the lower end...

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 [0001] The invention belongs to the field of root box test devices for planting plants, in particular to a root box test device suitable for studying plant rhizosphere micro-domains, which can be used to simulate and study rhizosphere and non-rhizosphere soil. Background technique [0002] The rhizosphere refers to the part of the micro-soil area that is different from the soil in physical, chemical and biological properties due to the influence of plant root activities. The scope of the rhizosphere is very small, generally within a few millimeters from the surface of the root shaft. It exists not only in the radial direction from the root surface to the original soil body, but also in the longitudinal direction from the root base to the root tip. Because it is difficult to study rhizosphere micro-domains under field conditions, many researchers use self-made root boxes to simulate rhizosphere and non-rhizosphere soils, such as: Yao Jianhua et al. Period, t...
