A dry crop wet damage identification device and identification method thereof

Abstract

A dry crop wet damage identification device comprises a water supply pipe, a water storage tank, a water level monitoring unit and a water pump, wherein the water supply pipe and the water storage tank are arranged in a test area; and the water level monitoring unit and the water pump are arranged outside the test area. The water level monitoring unit is used for detecting and controlling water level in the water storage tank; and a water flow channel is arranged in the test area. The dry crop wet damage identification device has the advantages that through the design of the dry crop wet damage identification device, the water level can be controlled automatically according to actual requirements so as to achieve waterlogging stress treatment of different degrees, and the requirements on moisture needed for normal growth of crops can be met by automatically controlling the height of underground water level during a non-waterlogging treatment period; that is, on the premise that the natural characteristics of soil of a planting area are maintained, wet damage research is performed on various dry crops, measurement errors of soil temperature and structure are avoided, and a research period is shortened. Through the design of an operation area, the interference of human factors is reduced, moisture permeate from bottom to top, and the problem that root systems are directly subject to impact due to water supply on the earth's surface, so that soil hardening is caused is solved.

Description

technical field [0001] The invention relates to the technical field of upland crop cultivation, in particular to a dry crop wet damage identification device and an identification method thereof. Background technique [0002] As the global climate continues to warm, the frequency of various natural disasters, such as extreme weather events such as high temperature, drought, and floods, will continue to increase. Wet damage, also known as waterlogging disaster: it is a disaster caused by excessive precipitation and poor drainage, which cause waterlogging and flooding of crops. It is one of the serious natural disasters faced by agricultural production; Too much, the impact when it reaches saturation is called waterlogging damage; part or all of the crops submerged by accumulated water is called waterlogging damage. [0003] Wet damage can lead to the imbalance of farmland ecosystem, such as the decrease of soil oxygen content, the decrease of soil temperature, the loss of nut...

AI Technical Summary

Problems solved by technology

[0004] Due to the relatively late start of research on waterlogging stress, the unclear regulatory network of plant waterlogging stress genes, and the difficulty of controlling experimental conditions, the research on the mechanism of waterlogging stress needs to be further strengthened and deepened.
