Container for analyzing crop root interaction in different cropping patterns

Abstract

The invention discloses a container for analyzing crop root interaction in different cropping patterns. Nylon membranes are arranged inside a basin body through a central support column and plastic strips, the central support column is arranged at the internal center of the basin body, the plastic strips are arranged at the bottom and the side wall of the basin body and uniformly divide the bottom and the side wall of the basin body into four parts, small grooves for fixing the edges of the nylon membranes are arranged on the plastic strips, and a concave hole for fixing the central support column is arranged at the bottom of the basin body. During assembly, the central support column only needs to be inserted into the concave hole of the basin body, and one ends, dripped with plastic liquid, of the nylon membranes are inserted into the small grooves of the plastic strips. The container is capable of beneficially preventing roots of two kinds or more than two kinds of crops from being crossed and growing together during intercropping, separate analysis on change of nutrient content in rhizospheres or in rhizosphere soil of one kind of crops and on root interaction relationship between two kinds or more than two kinds of crops is facilitated, and experimental errors caused by different soil sample collecting positions during soil sample collecting are avoided beneficially.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil fertilizers, and in particular relates to a container for analyzing the interaction between crop roots under different planting modes. Background technique [0002] Intercropping is the essence of traditional Chinese agriculture. Reasonable intercropping can not only improve the utilization rate of land, water and light energy, but also significantly improve the absorption and utilization efficiency of crops on nitrogen, phosphorus, potassium, iron and manganese and other nutrient resources. And the composition of soil microorganisms, and finally achieve the purpose of improving food production. Very early, people have studied the exudates of plant roots. As early as 1795 and 1830, Plenk and Decardolle observed that root exudates had growth-promoting and inhibiting effects on neighboring plants, respectively. In the 1950s, some researchers conducted systematic studies on root exudates ...

Problems solved by technology

[0004] The invention provides a container for analyzing the interaction between crop roots under different planting modes, aiming to solve the problem that people often use when intercropping to improve the absorption and utilization efficiency of crops on nitrogen, phosphorus, potassium, iron and manganese and other nutrient resources. Indoor or field experiments, especially in the process of analyzing the composition and content of soil nutrients in indoor experiments, generally adopt one or two (more than two) crops to be planted in ordinary pots, and then test the soil in different periods. However, when using ordinary pots for intercropping, the roots of two or more crops are likely to cross grow together, and it is difficult to analyze the changes in the nutrient content in the rhizosphere or rhizosphere soil of one crop separately, and The problem of the relationship between root interactions of two or more crops
