Embodiment 1

[0035] A special compound microbial fertilizer for wheat, its formula is, by weight percentage: 10% of ammonium sulfate, 15% of urea, 8% of diammonium phosphate, 18% of potassium chloride, 39% of peat, 8% of compound microbial bacterial liquid, sulfuric acid Zinc 0.5%, borax 0.5%, ferrous sulfate 0.5%, manganese sulfate 0.5%.

[0036]The said composite microorganism liquid is obtained by fermentation of Bacillus laterosporus, whose preservation number is CGMCC No.5090, and Bacillus subtilis, whose preservation number is CGMCC No.5091. , and then mixed according to the weight ratio of 1:1.

[0037] The preparation technology of Bacillus lateralis bacterium liquid is as follows:

[0038] First activate the strain of Bacillus lateralis, then rinse the slope with 5ml of sterile water to form a bacterial suspension, and put the bacterial suspension into a 500ml triangular flask containing 100ml of new 1 liquid medium, and cultivate it on a shaker for 18 Hours, the culture conditi...

Abstract

The invention provides a compound microbial fertilizer special for wheat and a preparation method thereof. The compound microbial fertilizer comprises a microbial bacteria liquid and an organic inorganic composite fertilizer, and comprises, by weight, 5-15% of ammonium sulfate, 10-20% of urea, 5-13% of diammonium phosphate, 15-23% of potassium chloride, 35-40% of turf, 5-10% of composite microbial bacteria liquid, 0.2-0.7% of white copperas zinc sulfate, 0.2-0.7% of borax, 0.2-0.7% of ferrous sulphate and 0.2-0.7% of manganese sulfate. The composite microbial bacteria liquid is mixed from new brevibacillus laterosporus and bacillus subtilis bacteria liquid. The special fertilizer can solve problems of excessive chemical fertilizer application, weak pertinency and unbalanced nutrient of an existing fertilizer for wheat, and a problem of unstable application effect of an existing microbial fertilizer, and can increase yield obviously after application.

Description

technical field [0001] The invention relates to a special fertilizer for wheat and a preparation method thereof, in particular to a compound microbial fertilizer special for wheat and a preparation method thereof. Background technique [0002] Wheat is one of the important crops. Its fertilization is mostly chemical fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate, and a few concentrated general-purpose compound fertilizers. Soil compaction destroys the soil aggregate structure. Although the general-purpose compound fertilizer is applicable to a wide range of areas and crops and types, for a certain crop, one or two nutrients may be excessive, while other nutrients may be insufficient, resulting in some The waste of nutrients has brought serious problems of excessive fertilization and unbalanced nutrient supply to wheat production. Because these fertilizers do not consider the local soil nutrient supply status and the amount of nutrients absorbed by...
