Green prevention and control method for diseases and insect pests in rice planting

Abstract

The invention provides a green prevention and control method for diseases and insect pests in rice planting. The green prevention and control method comprises the following steps of soil selection andtreatment, specifically, selecting a dry field which is high in terrain, high in dryness, good in drainage and free of rice planting for many years, cleaning residual fallen leaves and weeds on the soil, deeply ploughing the soil by 30-40 cm for airing 20-25 days before sowing, and disinfecting the soil by 3-4 kg of potassium permanganate per mu; seed selection and treatment; mechanical plowing and rice seedling transplanting; and green prevention and control of the diseases and insect pests. By means of the green prevention and control method, according to the situation of the diseases and insect pests in the rice growth period, pesticides are scientifically applied, residues are few, the residual time is short, the use amount of the pesticides in the rice production process is reduced,and the occurrence of large-area diseases and insect pests of rice is effectively controlled and prevented.

Description

technical field [0001] The invention is a green prevention and control method for rice planting diseases and insect pests, which belongs to the technical field of diseases and insect pests prevention and control. Background technique [0002] Rice is a cereal crop belonging to the Oryza genus. Rice is native to China and India. The ancestors in the Yangtze River Basin in China planted rice seven thousand years ago.

Problems solved by technology

[0003] At present, the vast majority of farmers in China value rice production and take the current economic benefits as the first goal. Therefore, they have adopted a variety of unhealthy planting methods and field management models, such as the extensive use of chemical fertilizers that lead to deterioration of soil quality, and unclear control over irrigation. , not only wasting a lot of water resources, but also not getting the desired effect, etc. If you want to realize the green and sustainable development of rice planting, you need more sophisticated and scientific planting management technology
