Test method for crop root development test observation room

Abstract

The invention relates to a test method for a crop root development test observation room. Parallel tests of crop root systems are carried out in the observation room, and gravity water and combined water at different depths are extracted, so that the water and fertilizer condition research is carried out. The observation room is a basement, and a plurality of planting pipes, a gravity water collecting system and a combined water extracting system for the parallel tests are arranged in the basement; the tops of the planting pipes correspondingly penetrate through reserved holes formed in the top of the basement and are fixed to the ground, and the bottoms of the planting pipes are arranged in the basement through a support; the gravity water collecting system and the combined water extracting system are all arranged on a wall of the basement. The method has the advantages that the structural design is reasonable and installation is convenient, the crop growth space and the soil environment can be controlled, and growth requirements of the root systems can be met. Meanwhile, the parallel tests and research about the water and fertilizer condition of the gravity water and the combinedwater under different depths can be carried out, soil is convenient to replace, and comprehensive research can be conducted by applying a plurality of research methods.

Description

technical field [0001] This patent application relates to the field of agricultural technology, in particular to a test method for an observation room used in crop root development tests. Background technique [0002] The root is the underground part that maintains the body axis of the crop body, and the whole of the roots of the underground part of the crop body is called the root system. For a long time, crop science has carried out a lot of research on the structure and function of aboveground organs of crops and the regulation of luminous system around the formation of yield, and achieved remarkable results. However, due to the limitations of research methods and working conditions, the research on the root system of the underground part of crops is far behind that of the aboveground part. With the development of science and technology, the research methods of root system are also constantly improved and perfected. All research institutions attach great importance to it...
