Organic rice planting method in hilly areas of Sichuan Basin

Abstract

The invention belongs to the agricultural technology field and particularly relates to an organic rice planting method in hilly areas of the Sichuan Basin. The technologies of selecting high-quality disease-resistant varieties, dry seedbed seedlings, box cultivation, surface coating, triangular sparse cultivation, seedling transplanting and frequency-oscillation insecticidal lamp pest control areorganically integrated, through mulching films, the soil temperature in the early stage is improved, evaporation of the soil surface is reduced, release of nutrients from organic fertilizers is accelerated, the number and density of weed species are reduced, and diseases such as banded sclerotial blight and false smut are reduced; frequency-oscillation insecticidal lamps are utilized to control rice pests; triangular sparse cultivation can not only save seeds and seedlings, but also help to reduce competition between crops, improve the photosynthetic rate and coordinate rice individual and group conflicts; through box cultivation, the water-free layer on a box surface of box furrow irrigation has functions of water conservation and water use efficiency improvement. The method is advantagedin that main problems of organic rice production in the hilly areas of the Sichuan Basin are solved, and green yield increase is achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for planting organic rice in the hilly area of ​​the Sichuan Basin. Background technique [0002] With the development of my country's chemical industry, the excessive application of chemical fertilizers and chemical pesticides in agricultural production is very common, resulting in more and more serious problems of agricultural non-point source pollution and agricultural product quality and safety. my country's agricultural development must follow the strategic deployment of "changing the mode and adjusting the structure" to realize the safety of the ecological environment and the quality and safety of agricultural products while ensuring national food security. It is very important to develop organic cultivation and realize green production increase. The hilly area of ​​the Sichuan Basin is the main rice producing area in my country, with 2 million hec...

AI Technical Summary

Problems solved by technology

However, there are several main problems in the traditional way of growing organic rice: first, the slow release of nutrients in the early stage of organic fertilizers leads to less tillering of rice; second, there are many weeds in the field; third, rice diseases and insect pests are serious
