Problems solved by technology

Airborne diseases can be mitigated to some extent by directing UV rays on plants, but have no effect on root-infested diseases and insects because UV light does not penetrate the soil

Abstract

The invention relates to a device for improving disease resistance of plants. The device comprises a light intensity sensor and a light source; the light intensity sensor is used for detecting photon flux density of photosynthetically active radiation for the surface of a plant; the light source is used for emitting red light; if the photon flux density of photosynthetically active radiation is less than a preset threshold, the red light of predetermined intensity is used to irradiate the plant. The device is characterized in that the predetermined threshold is 30Mumol/m<-2>/s<-1>, and the predetermined intensity of the red light is 0 to 200Mumol/m<-2>/s<-1>. The invention further relates to a method for improving the disease resistance of plants. The red light generated by the artificial light source to irradiate the plants, and loss caused by disease damage can be effectively reduced; the method is environment friendly, resistance of the plants can be enhanced just with light of relatively low intensity, and biomass and yield of the plants are increased further.

Description

technical field [0001] The invention relates to a device and a method for improving plant disease resistance, in particular to a device and a method for reducing the damage of root-knot nematodes. Background technique [0002] For a long time, agricultural crops have been attacked by many pathogens (such as insects, bacteria, viruses, etc.). Up to now, more than 80 kinds of nematodes have been reported to endanger agricultural crops, and root-knot nematode ( Meloidogyne javanica ) has the most serious impact on agricultural production, and it is one of the main pests that cause crop yield reduction. Root-knot nematode is a kind of soil-borne plant parasitic nematode that causes serious damage to a variety of crops, causing the host to reduce production by 15%-25% all the year round, sometimes reaching more than 70%. After the root-knot nematode infects the root system, it will seriously affect the development of the root system of the plant, and a large number of root-knot...
