Problems solved by technology

At present, the prevention and control of sorghum diseases and insect pests generally follows the principle of prevention first, and prevents diseases and insect pests early, but there are few reports that can effectively prevent and control diseases in terms of cultivation methods, only using reasonable cultivation methods to achieve sorghum. increase in production, and once the sorghum is seriously attacked by diseases and insect pests, it will cause a large area of ​​reduction

Abstract

The invention belongs to the technical field of planting and particularly relates to a sorghum cultivation method capable of reducing diseases and achieving high yield. According to the method, aftersoil preparation and ridging on a garden, sorghums are planted, intercropping of vetches and astragalus sinicus is carried out, and different kinds of fertilizer are cooperatively applied. Under-forest illumination of sorghums is utilized to the maximum degree, the energy conversion efficiency of land is increased, and the productivity effect of the land is maximized. Moreover, through scientificmatching of fertilizer during cultivation, the fertilizer efficiency of soil is comprehensive, the absorption rate is high, the fertilizer is safe, reliable and easy to absorb, and the method is conducive to large-scale planting.

Description

technical field [0001] The invention belongs to the technical field of planting, in particular to a sorghum cultivation method for reducing diseases and realizing high yield. Background technique [0002] As we all know, my country is a country with large agricultural production and a large population. Sorghum has been cultivated as an agricultural food crop for many years in my country and even in the world. my country's sorghum planting area is very extensive. The sorghum planting area in seven southern provinces and cities alone has reached more than 70 million mu. The perennial planting area accounts for 1 / 4 of the country's grain crop area, and the total output accounts for about 1 / 3 of the country's total grain output. Sorghum is a longevity food, rich in protein, fat, vitamins, trace elements, etc., and has high nutritional value. Although the current annual production of sorghum in my country has developed rapidly, there is still a large gap with the market demand o...
