Problems solved by technology

There is a record of using neem seeds to extract neem in foreign countries. Due to the low content of neem, the extraction process is more complicated, the production cost is higher, and the residue after extracting neem can not be fully utilized.
After retrieval, there is no report on the use of neem to directly produce nitrification inhibitors in my country, and there is no relevant report on the use of neem seeds to produce bio-fertilizers.

Embodiment Construction

[0013] The present invention adopts Aspergillus awamori (Aspergillus awamori) strain AS3.2576 and AS3.2783, Glomus mossae (Glomus mossae) strain SY0115 which have the effect of dissolving phosphate, and adopts the Bacillus subtilis (Bacillus subtilis) strain which has the function of promoting plant growth. 92012 and Geotrichum candidum (Geotrichum candidum) bacterial strain AY93041 are used as bacterial classifications, wherein coccidioides Morinii is provided by Beijing Academy of Agriculture and Forestry Sciences, and other bacterial classifications are all purchased from CGMCC; The above-mentioned bacterial classifications are cultivated and expanded by solid culture method, so that each gram of microbial agent Bacterial content ≥ 200 million: The cultured and expanded strains are mixed according to the ratio of 3:1:3:2 to make a mixed bacterial agent.

[0014] Then according to the weight ratio, after mixing 8% of the mixed bacterial agent with 52% of the organic compound ...

Abstract

The biological composite fertilizer containing margosine is prepared through culturing with Bacillus subtilis, geotrichum candidum and other mold varieties to form mixed bacterial preparation; and mixing the mixed bacterial preparation with organic compound, urea, phosphate ore powder and chinaberry seed powder in certain proportion. The biological composite fertilizer containing margosine can inhibit nitrification, raise the utilization of nitrogen fertilizer, produce certain mouse repelling effect, active soil nutrients, improve quality of crop, and promote crop growth.

Description

technical field [0001] The invention belongs to biological fertilizers, in particular to a biological compound fertilizer containing neemin and a preparation method of the fertilizer. Background technique [0002] Urea is the largest amount of nitrogen fertilizer in Asia and even the world, accounting for more than 85% of nitrogen fertilizer production. However, after nitrogen fertilizer is applied, it is easily decomposed into ammonia under the action of urease. A part of ammonia volatilizes in a gaseous state, especially in soils with high pH, ​​and its loss rate is as high as 50% or more; a part of ammonia is oxidized by nitrifying bacteria into nitrate nitrogen, which will be lost by leaching and denitrification. The utilization rate of nitrogen fertilizer is usually only 40% to 45%, or even lower. For this reason, N carriers and nitrification inhibitors for crop nitrogen fertilizers are being developed all over the world to improve the efficiency of nitrogen fertilize...
