Comprehensive green prevention and control method for rice field diseases and insect pests

Abstract

The invention relates to a comprehensive green prevention and control method for rice field diseases and insect pests, and belongs to the technical field of agricultural disease and insect pest prevention. The comprehensive green prevention and control method for rice field diseases and insect pests comprises agricultural measures, biological prevention and control and green chemical prevention and control. The agricultural measures comprise the following steps that (1), rice-green crop rotation is carried out; (2), strong seedlings are bred; and (3), scientific fertilization is carried out. The biological prevention and control method comprises the following steps that (1), trichogramma is released in the field; (2), vetiver grass is planted for trapping; (3), flowering plants are planted; and (4) the pests are trapped and killed with a sex attractant. The green chemical prevention and control specifically comprises the step of selecting a green biological pesticide for prevention in the early stage of pest and disease damage. According to the comprehensive green prevention and control method for the rice field diseases and insect pests, systematic and comprehensive green prevention and control measures are adopted for different diseases and insect pests in the whole growth season of rice through agricultural measures, biological prevention and control, green chemicals and other methods, and the purpose of comprehensive green prevention and control of the rice field diseases and insect pests is achieved.

Description

technical field [0001] The invention relates to a comprehensive green prevention and control method for rice field diseases and insect pests, which belongs to the technical field of agricultural diseases and insect pests prevention and control. Background technique [0002] Rice is an annual aquatic herb of the Gramineae family. The stalks are erect, 0.5-1.5 meters high, varying with varieties. Rice is an important cereal widely grown in tropical Asia. The fruit of rice is rice paddy, and paddy paddy is called rice, fragrant rice, paddy rice or rice after shelling. Nearly half of the world's population feeds on rice; my country's dependence is even higher, with more than 65% of the population taking rice as a staple food. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining, and rice husk and rice straw can be used as feed. The main rice producing areas in my country are mainly the Northeast region, the Yangtze...

[0004] Chemical control requires the use of a large amount of organic chemical pesticides, chemical pesticides entering the environment can directly cause water and soil pollution, especially the pollution caused by pesticide packaging waste is more serious; in addition, it will cause pesticide residues, affect the quality of agricultural products, and ultimately affect the quality of agricultural products. Consumers have adverse effects; a large number of organic chemical pesticides can also kill insect natural enemies and beneficial microorganisms at the same time. Insect natural enemies play a role in controlling the increase in the population of pests through parasitism or predation, and beneficial microorganisms inhibit the growth of original bacteria through antagonism. Reproduction, while using chemical pesticides to eliminate diseases, insects and other harmful organisms, it will also kill a large number of insect natural enemies and beneficial microorganisms, so that harmful organisms will lose the control of natural enemies, which will lead to the resurgence of harmful organisms

Long-term use or unscientific use of chemical pesticides will also cause resistance to pests and diseases, increase the difficulty of control, increase the use of pesticides, and cause a vicious circle

[0005] At present, although there are some green prevention and control methods in paddy fields, most of them are carried out for a certain kind of pests and diseases. However, there are many types of pests and diseases in paddy fields, the occurrence time span is large, and the occurrence level is different. Therefore, the prevention and control of paddy field pests and diseases should be It is a comprehensive and systematic work, and it is difficult to meet the prevention and control requirements with a single or one-sided method
