A high-efficiency crop rotation fertilization method for alleviating continuous cropping obstacles and increasing peanut fruit filling rate

Abstract

The invention relates to an efficient crop-rotation fertilizing method for relieving continuous cropping obstacles and increasing the full-fruit rate of peanuts. The method comprises the following steps: winter wheat is fertilized and seeding is carried out; after the wheat is harvested in the next year, ridging is carried out at places 10-15 away from two sides of wheat roots; a peanut base fertilizer is applied, wherein the peanut base fertilizer comprises a special compound fertilizer for peanuts, calcium superphosphate and humic acid raw powder; after the peanut base fertilizer is applied,peanuts are sowed by adopting a sowing mode of two grains in one hole; a special leaf fertilizer special for peanuts and chitosan oligosaccharide are applied by a foliage spraying method in a poddingand full fruiting period of the peanuts, so that the formation of peanut pods is promoted; and when the color of peanut leaves turns yellow and stems and leaves at the middle-lower part are withered,the peanut pods can be harvested. According to the invention, through the change of the fertilizers and the fertilizing modes on the basis of crop rotation of the wheat and the peanuts, the physicaland chemical properties of soil can be improved, the soil fertility can be improved, the influence of diseases and insect pests on peanuts can be reduced, the continuous cropping obstacles of the peanuts can be relieved, the vigorous growth of the peanuts is promoted, the full-fruit rate of the peanuts is increased, the peanut yield is increased, and the sustainable development of peanut industryis facilitated.

Description

technical field [0001] The invention relates to a high-efficiency crop rotation fertilization method for alleviating continuous cropping obstacles and increasing the peanut fruit filling rate, and belongs to the technical field of agricultural fertilization. Background technique [0002] Peanut (Arachis hypogaea L.) is an important economic crop and oil crop in my country. The total output of peanut in China accounts for about 50% of the total output of oil crops. Among domestic oil crops, peanut per unit yield, total output and export volume rank first , and with the in-depth adjustment of the planting industry structure nationwide, the production scale of staple grain crops shows a continuous decreasing trend, and the production scale of peanuts continues to increase. Compared with other oil crops, peanut has the characteristics of large production scale, high planting efficiency, high oil yield, good oil quality, and strong competitiveness in the international market. Ther...

Problems solved by technology

[0004] At present, the continuous cropping obstacles of peanuts are mainly prevented and solved by changing crops, selecting varieties resistant to continuous cropping, using biological agents, and using special fertilizers for continuous cropping. Conventional fertilizers and farming methods cannot alleviate continuous cropping obstacles. Therefore, there is an urgent need to A planting system that combines efficient and reasonable tillage and fertilization, in order to obtain higher returns while saving costs, and can alleviate continuous cropping obstacles, improve soil conditions, and reduce pests and diseases

[0005] In addition, when the peanut kernels are formed, various trace elements cannot meet the growth needs of peanuts, so the peanut filling rate is low, and the peanut production volume decreases. How to improve the peanut filling rate and increase the peanut production volume is the main topic of peanut planting research. , one of the problems
