System for monitoring physiological water in crop leaves

Abstract

The invention relates to the technical field of nondestructive monitoring of physiological information of crops, and discloses a system for monitoring physiological water in crop leaves. The system comprises a nondestructive leaf water content detection module, wherein the nondestructive leaf water content detection module comprises an infrared light source emitter, a detection sample table and a transmitted / reflected light intensity detection component; the detection sample table is made of transparent glass; a narrow-band filter is arranged on the surface of the sample table; infrareds emitted by the infrared light source emitter are projected on a sample; the transmitted / reflected light intensity detection component is respectively used for detecting the intensity of transmitted / reflected light of the infrareds transmitted / reflected by the sample. The system disclosed by the invention can be used for quickly and accurately acquiring water condition information of the crops, is easy to operate, can realize the nondestructive detection and has the advantages of being small in size, high in sensitivity and quick to response.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of crop physiological information, in particular to a monitoring system for crop leaf physiological moisture. Background technique [0002] Water is an important substance for crop growth, and it is also the largest consumable in the process of crop growth. The water content of plant leaves is an important physiological index to represent the water information of plants, and it has been widely used in the research of plant physiology and drought resistance. How to quickly and accurately obtain the water status information of plants, especially the water content of plant leaves, is of great significance for studying the physiological and biochemical reactions of plants, mastering the growth and development process of plants, and guiding water-saving irrigation. Traditional plant leaf moisture measurement methods include drying method, distillation method, titration method, electr...

AI Technical Summary

Problems solved by technology

Traditional plant leaf moisture measurement methods include drying method, distillation method, titration method, electrical measurement method, etc. The existing methods all need to collect samples and measure them under laboratory conditions, which usually takes a long time, complicated operation, and high detection cost. High, single measurement data, only of scientific research significance, not suitable for on-site monitoring and adjustment of crop growth
