Rice disease and pest control method for rice and shrimp field

Abstract

The invention provides a rice disease and pest control method for a rice and shrimp field. The rice disease and pest control method for the rice and shrimp field comprises the following steps that the field is ploughed and insolated before planting rice, an agent A is mixed into the soil of the rice field, irrigating, changing water and the like are conducted in the rice field, eggs and harmful bacteria are removed in the soil, and the rice field is treated by adopting an agent B and an agent C according to different growth periods of the rice, a double-wave lamp comprising a black light lamp and an electrodeless fluorescent lamp is arranged, and pesticide and an insecticidal lamp are combined to reduce the occurrence of rice diseases and insect pests; according to the pathogenic condition of the rice diseases and pests and the action characteristics of the agent A, the agent B and the agent C, corresponding agent application time is selected in different growth periods of rice, effective prevention and treatment of the diseases and pests are achieved, the using amount of the agents is reduced, the agent C used after a tillering stage is harmless to crayfish and has no influence on the growth vigor of the rice, and green prevention and control of the rice diseases and insect pests can be realized.

Description

technical field [0001] The invention relates to the technical field of ecological planting and breeding, in particular to a method for preventing and controlling rice diseases and insect pests in rice and shrimp fields. Background technique [0002] The "rice-shrimp co-cropping" model is a three-dimensional planting model that combines rice planting and crayfish farming. This production model can make full use of the shallow water environment of the paddy field and the winter slack period, effectively improve the economic benefits per unit area of ​​the paddy field, and improve the use of water resources. It can realize dual-use of one land and two harvests of one water. At the same time, it can further reduce agricultural non-point source pollution and aquaculture tail water pollution. The results of existing studies show that the growth and development of rice planted in the three-dimensional rice-shrimp farming model is better than that of rice planted in traditional meth...

AI Technical Summary

Problems solved by technology

The results of existing research show that the growth and development of rice planted in the three-dimensional rice-shrimp farming model is better than that of rice planted in traditional methods. However, because crayfish are sensitive to many pesticides, they are generally used in the "rice-shrimp co-cropping" model. Pesticide preparations or the use of non-pollution pesticides, but without the use of pesticide preparations, rice is susceptible to pests and diseases. The control effect of non-pollution pesticides is poor, and it is easy to affect the growth of crayfish, which brings certain challenges to rice pest control technology.
