Organic fertilizer biologically fermented through soyabean protein

Abstract

The invention discloses organic fertilizer biologically fermented through soyabean protein. A biological fermentation bacterial agent and rice chaff are mixed uniformly as per the weight ratio of 1:10 to form fermenting materials, the fermenting materials are added into raw materials, then auxiliary materials are added, the mixture is mixed uniformly to form fermentation materials, the fermentation materials are stacked and fermented for 6-8 days at the high temperature in a range of 60-65 DEG C, the weight ratio of the fermenting materials to the raw materials is 1:1000, the auxiliary materials comprise one or more of livestock excrement, straw, manioc waste and distillers' grains, the weight ratio of the auxiliary materials to the raw materials is 1:(5-6), and the raw materials are bean cakes. By the aid of the process, the composting time can be shortened, the organic fertilizer is non-toxic, harmless and free from peculiar smell and environmental pollution, meanwhile, nutrients can be preserved, and the organic content of the fertilizer is improved so as to improve the quality of the fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a soybean protein biofermentation organic fertilizer. Background technique [0002] Organic fertilizer refers to the use of various animal wastes (including animal manure, animal processing waste) and plant residues (cake fertilizer, crop straw, fallen leaves, dead branches, peat, etc.), using physical, chemical, biological or a combination of the three. Some treatment technologies, through certain processing techniques (including but not limited to composting, high temperature, anaerobic, etc.), eliminate harmful substances (pathogens, pest eggs, weed seeds, etc.) to achieve harmless standards A type of fertilizer formed. [0003] Bean cake is a by-product of oil extraction from soybeans (mainly soybeans and black beans), and has the highest nutritional value among various plants. Generally speaking, the digestibility of dry matter per kilogram of bean cake is more than 3000 kcal, a...

Problems solved by technology

However, if the existing bean cake is used as fertilizer, if it is directly applied, the amount of application needs to be controlled, otherwise it will cause burnt seedlings; and after fermentation, the fermentation time for the existing compost to reach the harmless index is generally 45-60 days , the cycle is long, the cost is high, and during the composting process, the surrounding area of ​​the compost is foul smelling, the sewage flows, mosquitoes and flies breed, and the environment is seriously polluted
