Microbial composite soil conditioning fertilizer

Abstract

The invention discloses a microbial composite soil conditioning fertilizer which is prepared from the following raw materials in parts by weight: 10 to 25 parts of monoammonium phosphate, 15 to 30 parts of urea, 25 to 35 parts of potassium chloride, 0.5 to 3 parts of manganese chloride, 0.5 to 2 parts of calcium hydrophosphate, 15 to 25 parts of gluconacetobacter xylinus, 20 to 30 parts of bacillus amyloliquefaciens and 25 to 35 parts of sphingobacterium thalpophilum. According to the microbial composite soil conditioning fertilizer disclosed by the invention, the stalk decomposing speed is quickened by adding microbial agents of the gluconacetobacter xylinus, the bacillus amyloliquefaciens and the sphingobacterium thalpophilum; thus, crop nutrient absorption and utilization are improved.By means of adding metal manganese ions and calcium ions, permeability of microbial cells is improved, and nutrient absorption is facilitated; thus, decomposition of the microbial agents of the gluconacetobacter xylinus, the bacillus amyloliquefaciens and the sphingobacterium thalpophilum to the stalks is improved. In addition, an experiment process shows that when the three microbial agents of the gluconacetobacter xylinus, the bacillus amyloliquefaciens and the sphingobacterium thalpophilum are simultaneously added, the decomposing speed of the microbial agents to the stalks can be optimal.

Description

Technical field [0001] The invention belongs to the field of soil conditioning fertilizer, and in particular relates to a microbial composite soil conditioning fertilizer. Background technique [0002] In the long-term agricultural production, in order to meet the society's increasing demand for food products, people use a large amount of arable land unreasonably and use chemical fertilizers and pesticides uncontrollably, which ultimately leads to soil compaction, reduced soil fertility, and low fertilizer utilization. Affect the normal growth and yield increase of food crops. [0003] Returning straw to the field is a measure to increase fertility that is generally valued in the world today. It eliminates air pollution caused by straw burning and also has the effect of increasing fertilizer and production. Returning straw to the field can increase soil organic matter, improve soil structure, make soil loose, increase porosity, reduce capacity, and promote microbial activity and t...

Problems solved by technology

However, there are still many problems in the promotion of the technology of straw returning to the field as a fertilizer. Among them, the promotion of the technology of returning straw to the field has great resistance, and the main reason is closely related to the difficult-to-degrade texture of the straw itself.

After the straw is directly returned to the field, it takes a long time for it to be decomposed and transformed by soil microorganisms in the soil, so it cannot be used as a fertilizer source for current crops
