Process for utilizing three abandoned proteins and thoroughly-decomposed cow dung to produce growth-promoting bio-organic fertilizer and product thereof

Abstract

The invention provides a process for utilizing three abandoned proteins and thoroughly-decomposed cow dung to produce a growth-promoting bio-organic fertilizer and a product thereof and belongs to agricultural intensive production technologies. A used formula comprises, by dry weight, 75% of thoroughly-decomposed cow dung ordinary manure, 5% of alga ooze, 10% of abandoned feather puffing powder and 10% of rapeseed meal. A used strain is a growth-promoting bacillus amyloliquefaciens SQR-9. The process comprises mixing the raw materials according to the optimum formula, adding 5% of growth-promoting bio-control bacteria by volume mass, performing strip stack type fermentation, performing overturning once each day, and fermenting for 6-7d. The number of beneficial viable bacteria in the produced fertilizer is lager than 2*10<8>CFU / g by dry weight (similarly hereinafter), the content of total nitrogen is 2-3%, the content of total NPK nutrient is 6-8%, the content of organic matter is larger than 45%, and the content of microcystin LR and the content of microcystin RR are both lower than 4ug / kg. The growth-promoting bio-organic fertilizer is rich in beneficial amino acid, low in production cost and high in growth-promoting effect and can be applied to food crops and vegetables and the like.

Description

1. Technical field [0001] The invention provides a process and product for producing growth-promoting bio-organic fertilizer by using three kinds of waste protein and decomposed cow dung, which belongs to the agricultural intensive production technology. Significantly promotes crop growth. 2. Background technology [0002] In recent years, cyanobacteria blooms have occurred in major lakes at home and abroad, and the eutrophication of lakes has attracted increasing attention. The method of salvaging blue-green algae is currently very effective and not controversial in the academic circles. Because the water content of Laogao is relatively large, reaching 88%, and it occupies a large area, as a biomass resource, it is more meaningful to explore its resource utilization. Cyanobacteria blooms contain rich nutrients such as plant protein and polysaccharides. Transforming these resources will make it possible to realize the utilization of waste resources of cyanobacteria in Taih...
