System for implementing soil moisture management and moisture gradient authentication

Abstract

The present invention relates to crop planting management technology, and is especially one soil water management and water gradient identification system for drought resisting screening and identification of plants. The system includes rain sheltering and ventilating shed over the field, sprinkling irrigation unit and drip irrigation unit set inside the shed, deep drainage ditches around the field and with water permeating holes, TDR pipes mounted in the ends and middle parts of the diagonals of the field, and temperature sensors and humidity sensors in different positions inside and outside the shed. The system may be used in the gradient soil water management from enough water to drought condition while ensuring the other basically identical conditions, and has raised accuracy and reliability.

Description

technical field [0001] The invention belongs to crop planting management technology and a system for implementing soil moisture management and moisture gradient identification for drought resistance screening and identification of plants. It is a biological research technology to realize the scientific water management of crop planting and the cultivation of new drought-resistant varieties. Background technique [0002] Water resources are becoming an important factor restricting agricultural development in some countries, including my country. The development and efficient use of water resources and the cultivation of high-quality and high-yield plant varieties that are drought-resistant and water-saving to reduce agricultural water use have become global agricultural research hotspots. Since the mid-20th century, research on drought resistance of rice, wheat, corn, tobacco, Arabidopsis and other plants has been carried out from the aspects of morphology, physiology and bi...

AI Technical Summary

Problems solved by technology

Some drought resistance research conducted in the field, because the experimental materials are planted in different fields (such as dry fields and paddy fields), so the environmental differences have a great impact on the experiment, reducing the reliability and accuracy of the experiment

In 1999, at the international symposium on "Crop Genetic Improvement Using Molecular Pathways to Stabilize Crop Yield in Arid Areas" held in Mexico, the famous plant physiologist Dr. Blum pointed out that the main reason for the little progress in drought resistance research in the past was the identification of drought resistance It is difficult to reflect the actual growth status of the plants with advanced technology and standards
