Growth-promoting bacteria for facilitating growth of rape and microbial organic fertilizer

Abstract

The invention relates to growth-promoting bacteria for facilitating growth of rape and microbial organic fertilizer, and belongs to the intensive agriculture production technique. The microbial organic fertilizer is prepared in the following steps of separating antagonistic bacteria NJZJSB 3, inoculating into a microbial decomposition mixture of thoroughly decomposed pig manure compost and rapeseed meal to carry out solid fermentation to obtain the microbial organic fertilizer, wherein the microbial organic fertilizer comprises more than 1*10<8>cfu / g growth-promoting bacteria, the content of full nitrogen is 4-5% (the content of organic nitrogen is more than 90%), the total nitrogen phosphorus and potassium nutrient is 6-10%, and the content of organic matters is not lower than 45%. Based on an experiment result, the fresh weights of ground parts, underground parts and the whole strain of rape are respectively up to 154.6%, 114.7% and 148.4% so that the growth of the rape can be effectively facilitated if the microbial organic fertilizer is applied in successive years.

Description

1. Technical Field [0001] The invention relates to a growth-promoting strain used to promote the growth of rapeseed and its microbial organic fertilizer, belonging to the technical field of agricultural intensive production. 2. Background technology [0002] Rape is an important oil crop in our country, and it plays an important role in the construction of the national economy. Promoting the growth of rapeseed and increasing the yield of rape are always important topics in the agricultural economy. In the process of rapeseed planting, due to the long-term investment of a large amount of chemical fertilizers, the soil environment where the rape grows is destroyed, the soil biological activity is severely reduced, and the number and number of beneficial microorganisms in the soil are reduced, resulting in the continuous decline of rape production. Therefore, the development of new fertilizers that promote the growth of rape is very important for the production of oil crops. [0003...

AI Technical Summary

Problems solved by technology

[0003] The incineration of crop straws in our country and the disposal of livestock and poultry manure after large-scale breeding not only seriously pollute the environment, but also greatly waste raw materials that can be used as organic fertilizers and bio-organic fertilizer products; a large number of nutrient resources are lost in soil-plants outside the system, it has obviously weakened the ability of my country's agricultural sustainable development
