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

Utilize poultry feather to produce method of microorganism organic fertilizer and products thereof
One, technical field
The present invention relates to method of utilizing poultry feather to produce microorganism organic fertilizer and products thereof, belong to intensive agriculture production technical field.
Two, background technology
Along with the fast development of China's poultry intensive culture, discarded poultry feather is also more and more, at present also not by comprehensive processing and utilization, throws aside everywhere, the situation of contaminate environment happens occasionally.Because poultry feather gross protein value is on average up to 75%-90%, the poultry feather not utilizing is a kind of waste of protein resource.The annual production of China's poultry feather has exceeded 700,000 tons according to the preliminary statistics, and because the tooling cost of feather meal is high, feather tankage are easy to cause environmental pollution, must be to its processing treatment.At present the processing and utilization of waste feathers is mainly concentrated on to four aspects below both at home and abroad: 1. animal-feed; 2. keratin membrane material; 3. with the copolymerization of other macromolecular material or compound; 4. amino acid fertilizer.In amino acid fertilizer application aspect, measure and show, feather keratin contains the necessary amino acid of 10 many animals such as abundant Methionin, methionine(Met), Threonine, tryptophane, Histidine, glycine, skin propylhomoserin, also contain major element, trace element, VITAMIN and some UGFs, and amino acid is also one of nutrient substance of plant-growth, therefore, waste feathers is rationally applied to biological organic fertilizer industry imperative.
Biological organic fertilizer is a kind of emerging bio-feritlizer, start from most the nineties in 20th century and use, refer to microorganisms with specific functions and mainly take plant and animal residues (as feces of livestock and poultry, agricultural crop straw etc.), have the fertilizer of microbial fertilizer and fertilizer effect concurrently for a class of originating and be composited through harmless treatment, the organic materials that becomes thoroughly decomposed.Phenomena shows, biological organic fertilizer plays very large active effect in agricultural, comprises nutrient is provided, and increases fertilizer efficiency, improves the absorption of crop to nutrient, regulates the active effects such as soil acidity or alkalinity.Biological organic fertilizer kind is more on the market now, but expensive, therefore, finds other substitute and carrys out Substitute For Partial aminoacid component, reduces costs, and just becomes the current problem that needs solution.This research is intended utilizing after the pig manure mixing of cheap waste feathers and different ratios, accesses different antagonistic strains and carries out secondary solid fermentation generation novel biological fertilizer.Discarded feather protein matter is hydrolyzed into amino acid, then prepares biological organic fertilizer together with the pig manure that becomes thoroughly decomposed, to making full use of the protein resource of waste feathers, alleviate the pollution of waste feathers to environment, and can greatly reduce production cost.
Three, summary of the invention

Feeding block seedlings raising and field-transplanting are all used special mixing microorganisms fertilizer, and the consumption of mixing microorganisms fertilizer is as follows: during feeding block seedlings raising, amount of application is 1.5%, and the amount of application while transplanting land for growing field crops is every 1.5kg (folding 225kg/ mu).Each processing repeated 3 times, and application quantity of nitrogen phosphorus potassium is consistent, conventional water and fertilizer management.
Table 2 is used the impact (Hainan Le Dong Hong Hu experimental plot) of microbial organic fertilizer on control banana soil biography blight
Result shows, in the field of (this season sickness rate is more than 15%) of seriously falling ill, banana Panama wilt disease can be controlled at below 5.5% (table 2), and control rate reaches more than 70%, promoted the growth of banana, its fruit increases production more than 28%.
3 cucumber
For verifying the prevention effect of microbial organic fertilizer of the present invention, gather cucumber continuous cropping morbidity soil and carried out pot experiment.Cucumber variety is Tianjin spring No. 4.
Test is processed as follows:
1) contrast 1 (CK1), without the healthy soil of continuous cropping soil biography damping-off;
2) contrast 2 (CK2), have continuous cropping soil to pass the morbidity soil of damping-off, use 2% common fertilizer D while growing seedlings;
3) CK2+NJN43 liquid bacterial agent;
4) microbial organic fertilizer (BIO2) of CK2+NJN43 and D secondary solid fermentative production;
5) microbial organic fertilizer (T7) of CK2+NJN43 and A secondary solid fermentative production;
