Crop rotation, intercropping and relay intercropping cultivation method for relieving continuous cropping obstacles of konjac

Abstract

The invention discloses a crop rotation, intercropping and relay intercropping cultivation method for relieving continuous cropping obstacles of konjac. According to the method, a crop rotation, intercropping and relay intercropping cultivation technology is integrated into a konjac planting system, and the konjac and green manure are subjected to crop rotation, so that the land utilization efficiency can be improved, the physical and chemical properties of soil can be improved, the soil fertility can be adjusted, and the continuous cropping diseases of the konjac can be effectively blocked; the konjac and high-stalk crops are intercropped, so that land, water, light and heat resources are fully utilized, and the high-stalk crops provide shading protection for the konjac; the konjac is subjected to relay intercropping to cover plants, and vegetation with proper density and height is rapidly formed on ridges, so that the growth of field weeds is inhibited, the earth surface temperaturein a high-temperature period is reduced, the soil moisture is kept, the diversity of soil organisms is increased, beneficial soil biological communities are promoted, and the growth and proliferationof harmful pathogenic bacteria of soft rot and southern blight are inhibited; and meanwhile, the crop rotation, intercropping and relay intercropping cultivation system interferes with the identification, positioning and damage of pests to the konjac, so that the survival of natural enemies is facilitated, the field pests are inhibited and killed, wounds caused by the pests on stems and leaves ofkonjac plants are reduced, the probability that the konjac is infected by the pathogenic bacteria is reduced, chemical herbicides, bactericides and insecticides do not need to be applied in the growthperiod of the konjac, the green, efficient and sustainable development of the konjac planting industry and the quality safety of konjac products are guaranteed, the konjac industry is greatly promoted, and the comprehensive and rapid development of economy and society in Shaanxi-Sichuan and Yunnan-Guizhou mountainous areas is promoted.

Description

technical field [0001] The invention belongs to the technical field of ecological regulation and control of economic crop diseases, and relates to an intercropping cultivation method for alleviating konjac continuous cropping obstacles. Background technique [0002] Konjac is also known as konjac. Its tubers are food materials and medicinal materials. They have the functions of reducing blood pressure, losing weight, diuresis, detoxifying, beautifying, appetizing, and preventing cancer. It has been identified as one of the top ten health foods by the United Nations Health Organization. Starch, protein, amino acid, glucomannan, trace elements, etc. are widely used in food, medical, chemical, paper, textile, petroleum and other industries, and are called "Oriental magic powder". Konjac is mainly distributed in tropical and subtropical countries and regions in Asia and Africa. my country is the country of origin and the first country of production. The annual planting area exce...

AI Technical Summary

Problems solved by technology

In order to avoid drought and flood, konjac is generally planted in ridges, but the weeds on the ridges are not good for the growth of konjac. The use of chemical herbicides is inevitable, which brings significant side effects to the ecological environment.
