Deep-ploughing-free compound microbial fertilizer

Abstract

The invention discloses a deep-ploughing-free compound microbial fertilizer, and each ton of the fertilizer contains 10-25 kg of polyacrylamide, 10-30 kg of bacillus subtilis, 5-25 kg of streptomyces microflavus, 5-20 kg of bacillus laterosporus, 1-4 kg of diethylaminoethyl hexanoate, 20-50 kg of a polyaspartic acid, 5-25 kg of EDTA (Ethylene Diamine Tetraacetic Acid), 10-30 kg of urea, 5-20 kg of potassium humate, and the balance of organic filler. The fertilizer disclosed by the invention is high in microbial activity and strong in biological stability, can be used for effectively improving the soil aggregate structure, eliminating the soil hardening, enhancing the infiltration capacity of soil, and improving the cushioning properties of soil, and can be used for alleviating the damages on crops caused by soil secondary salinization due to excess fertilization; and the fertilizer disclosed by the invention also can be used for promoting the growth and development of beneficial microorganisms in the soil, thereby improving the utilization rate of the fertilizer and promoting the root growth of crops, so that roots are developed, the disease resistance of crops is enhanced, and the yield-increasing effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of compound microbial fertilizer, and in particular relates to a compound microbial fertilizer without deep tillage. Background technique [0002] Due to the excessive use of chemical fertilizers and the continuous planting of crops, the soil began to compact on a large scale, and the beneficial bacteria in the soil became less and less. Few phenomena, especially underdeveloped fibrous roots, only transporting roots, in the shape of light rods, dark in color, or even rotted and dead, with very few white elongated roots and capillary roots; Poor, various physiological diseases and infectious diseases occur frequently. According to this situation, there is an urgent need for a high-tech microbial fertilizer to improve the aggregate structure of the soil, eliminate soil compaction, enhance soil infiltration capacity, make the root system developed, crops have strong disease resistance, and finally achieve the ...
