Root box test device suitable for growing of plants

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...
