Embodiment Construction

[0024] The action mechanism of the patent of the present invention is that the puffed feathers provide sufficient amino acid components and effective nitrogen sources in the fertilizer products. On the one hand, they are directly used by plants, and at the same time, they also provide good conditions for the cultivation of functional bacteria and microorganisms in the products. It quickly establishes the ecology and food chain of exogenous beneficial functional bacteria and microorganisms; in addition, functional bacteria produce a large amount of biomass-promoting substances, promote the growth of crops, and at the same time exert microbial functions.

[0025] The present invention has the advantages of adding a small amount of puffed feathers in the formula, which can replace the composting of rapeseed meal or microbial decomposition of rapeseed meal in the existing (patent) technology, greatly saving the cost by 25-55% (Table 6 ), saving farmers a lot of money.

Abstract

The invention relates to a method for producing a microbial organic fertilizer by utilizing poultry feathers and a product thereof, and belongs to an agricultural intensive production technology. According to the method disclosed by the invention, the puffed feathers are taken as amino acid source carriers, mature pig manure compost and microbes of rapeseed meal are mixed for decomposing a mixture, and solid fermentation is performed for preparing the microbial organic fertilizer. The fertilizer contains more than 1 multiplied by 10<8> / g of functional bacterial, 2-4% of total nitrogen (organic nitrogen accounts for more than 90%), 3-5% of total nitrogen, phosphorus and potassium and 25-35% of organic matters. Test results show that the waste feathers are puffed and then mixed with the pig manure compost, secondary fermentation is performed for producing the biological organic fertilizer, and the total effects are better.

Description

1. Technical field [0001] The invention relates to a method for producing microbial organic fertilizer by using poultry feathers and a product thereof, belonging to the technical field of agricultural intensive production. 2. Background technology [0002] With the rapid development of intensive poultry farming in our country, more and more poultry feathers are discarded, which have not been comprehensively processed and utilized at present, and the situation of discarding anywhere and polluting the environment occurs from time to time. Since the average crude protein content of poultry feathers is as high as 75%-90%, unused poultry feathers are a waste of protein resources. According to preliminary statistics, the annual output of poultry feathers in my country has exceeded 700,000 tons. Due to the high processing cost of feather meal, feather waste is easy to cause environmental pollution and must be processed. At present, the processing and utilization of waste feathers ...
