Organic fertilizer specially used for planting peanuts on saline-alkali soil

Abstract

The invention relates to the technical field of organic fertilizers and especially relates to an organic fertilizer specially used for planting peanuts on saline-alkali soil. A preparation method includes: A) producing a microbial agent and B) producing the organic fertilizer, wherein the composite microbial powder prepared in A) is inoculated on composting vinegar residue compost with uniform stirring; then the material is fermented in a windrow stacking manner, thus preparing the organic fertilizer specially used for planting peanuts on saline-alkali soil. In the technical scheme, the microbial strain is subjected to amplified inoculation on a culture medium then is cultured in a culture box to mature; then the strain is inoculated on a culture solution for shake cultivation and then issubjected to secondary fermentation in a fermentation tank; finally, single bacteria, prepared through the fermentation, is absorbed by a carrier to obtain a single microbial agent. Through the method, bacillus subtilis, bacillus mucilaginosus and streptomyces microflavus are mixed according to ratio and are pulverized to prepare a compounded microbial powder; then the compounded microbial powderis inoculated on the composting vinegar residue compost with uniform stirring; and finally the material is fermented in a windrow stacking manner, thus preparing the organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a special organic fertilizer for peanut cultivation in saline-alkali land. Background technique [0002] Soil salinization is increasingly threatening the limited land resources on which human beings depend. Under the severe pressure of increasing population, dwindling cultivated land and insufficient fresh water resources, how to use large areas of saline-alkali land, desertified land and other resources to develop agriculture has become a major issue. [0003] Peanut is an important food crop and is moderately sensitive to salt stress. Under saline conditions, its yield decreases, and salt-sensitive varieties are more affected by salt stress than salt-tolerant varieties; meanwhile, peanuts are crops that require a large amount of fertilizer. The annual fertilizer requirement is about 8 million tons, accounting for 17-20% of my country's chemical fertilizer consumpti...

AI Technical Summary

Problems solved by technology

[0003] Peanut is an important food crop and is moderately sensitive to salt stress. Under saline conditions, its yield decreases, and salt-sensitive varieties are more affected by salt stress than salt-tolerant varieties; meanwhile, peanuts are crops that require a large amount of fertilizer. The annual fertilizer requirement is about 8 million tons, accounting for 17-20% of my country's chemical fertilizer consumption. However, long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity will drop significantly.

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
