Problems solved by technology

However, organic fertilizers also have the characteristics of low nutrient content, slow fertilizer efficiency, and low utilization rate in the current season, and the effect of increasing production is not as good as that of ordinary compound fertilizers.
At the same time, under continuous cropping obstacles, the structure of soil microorganisms is unbalanced, the content of beneficial microorganisms decreases, and the content of harmful microorganisms increases, which seriously affects the absorption and utilization of nutrients by peanuts, inhibits the growth of peanuts, and reduces peanut production.

Abstract

The invention relates to a peanut planting method for alleviating the peanut continuous cropping obstacle. The peanut planting method of the present invention comprises: before sowing peanuts, ditching and applying peanut base fertilizer, peanut sowing, spraying special foliar fertilizer and chitosan oligosaccharide, and normal field management. The peanut base fertilizer of the present invention is special compound fertilizer for peanuts, superphosphate, organic fertilizer and bacteria agent. The present invention finds for the first time that the Aspergillus niger agent and chitosan oligosaccharide act together, combined with the application of organic fertilizers, can significantly increase the total amount of microorganisms in the soil, and promote the increase in the number and types of bacteria, fungi and actinomycetes. Can significantly improve peanut continuous cropping obstacles.

Description

technical field [0001] The invention relates to a peanut planting method for relieving continuous peanut cropping obstacles, and belongs to the technical field of agricultural fertilization. Background technique [0002] Continuous cropping obstacle is one of the important factors limiting the yield and quality of peanut. Under continuous cropping obstacles, due to the accumulation of harmful substances in the soil and the imbalance of microbial flora, the nutrient utilization rate of common chemical fertilizers is low, and it is easy to cause defertilization and premature aging in the late growth period and reduce yield. The nutrient release rate of organic fertilizer is slow and lasts for a long time, and it can improve soil fertility and soil physical and chemical properties. However, organic fertilizers also have the characteristics of low nutrient content, slow fertilizer efficiency, and low utilization rate in the current season. The effect of increasing production is...
