Abstract

The invention provides a green planting method for controlling diseases and insect pests in a rice field. While planting rice, upland rice is interplanted, and different types of rice are intercropped by utilizing the characteristics of large genetic background differences of rice varieties, which has a very obvious control effect on rice blast , the control effect is as high as 68.53%, which is a major innovation in the continuous control of rice blast using biodiversity at home and abroad. Compared with the net planting, the yield of the intercropping model of hybrid rice and bar rice increased by 19.71%. The present invention further adopts the planting mode of planting nectar source plants such as Thioflower and Zinnia on the ridge of rice fields (especially the mixed planting of Thioflower and Zinnia in proportion), increases biodiversity, and adjusts the insect population in the farmland ecology structure, increase the number of natural enemies of pests (such as beneficial insects such as parasitic wasps), and reduce crop pests.

Description

technical field

[0001] The invention relates to the technical field of plant cultivation, in particular to a green planting method for controlling diseases and insect pests in paddy fields. Background technique

[0002] Rice is one of the most important food crops in my country. The increase of rice production and the control of diseases and insect pests have always been the focus of research by scientists. In the past, a large amount of pesticides and fertilizers were used in the process of rice planting. However, the extensive use of pesticides and fertilizers not only reduces soil The low nutrient content makes the soil stamina insufficient, and causes a series of problems such as the decline of rice field biodiversity (especially beneficial natural enemies), the improvement of resistance to diseases and insect pests, and the quality and safety of rice. Therefore, new environmental conditions are adopted in production practice. Friendly controls are imperative.
