Technical field

The invention belongs to soil fertilizer fields, are related to a kind of method of production of high buffer capacity organic fertilizer.

Background technique

South China is the low region of the maximum soil organic matter content in China, and content accounts for China lower than the soil of national average value The 70% of South domain.Use out of range chemical fertilizer influences soil fertility and causes serious environmental pollution for a long time.Therefore, pass through benefit With filter mud fermentations such as crop stem, filter mud of sugar refinery, animal wastes and rice brans at a kind of high buffer capacity organic fertilizer, and it is raw in agricultural Resource utilization is carried out in production, not only can solve the pollution problem of crop stem, filter mud of sugar refinery, animal wastes to environment, but also It can solve the soil fertility decline problem in agricultural production, turn waste into wealth, protect environment, promote the sustainable development of sugar industry industry.

Summary of the invention

In order to solve the above technical problems, the present invention provides a kind of high buffer capacity organic fertilizer and preparation method thereof and answers With to carry out resource utilization to the organic waste of agricultural generation and improve soil.

Technical solution of the present invention: a kind of high buffer capacity organic fertilizer is made, the organic materials of organic materials fermentation It by weight percentage include: that crop stem 35-40%, filter mud of sugar refinery 35-40%, animal wastes 15-20% and rice bran account for 3-5%.Make Object stalk, filter mud of sugar refinery, animal wastes and rice bran mass percent summation be 100%.The crop stem includes corn, water It is discarded to be also possible to branch, leaf, careless gardens for the farmings stalk such as rice straw.

The buffer capacity of solution is applied in organic fertilizer by the application for the first time.Inventor constantly gropes to innovate over 10 years, most It determines that with the buffer capacity of organic fertilizer be guidance eventually, is obtained by engineering means such as proportion, the fermentation conditions of adjusting raw material The organic fertilizer of high buffer capacity, compared with common organic fertilizer, acidic buffer capacity and alkali buffer capacity significantly improve the organic fertilizer, While providing nutritional ingredient to crop, the pH value of also adjustable soil solves the soil fertility decline in agricultural production Problem.

Wherein, the buffer capacity of organic fertilizer calculates the buffer capacity that can refer to solution, uses β as measurement, refers to unit bodies When the pH of product buffer solution changes 1 unit, the amount of the required substance that strong acid or highly basic is added.

Correspondingly, the present invention also provides a kind of preparation method of high buffer capacity organic fertilizer, including the following steps:

Step A: getting organic materials ready and crop stem is cut into 20-30 centimetres of section, by the crop stem cut and filter mud of sugar refinery, Animal wastes and rice bran mixing；

Step B: the bacterium song for being used for organic fertilizer production and organic materials are mixed, pile item in the fermentation workshop for having sun-rain-shading Band, allows its spontaneous fermentation；It is primary every turning in 7-9 days, the organic of high buffer capacity is arrived after spontaneous fermentation in 22-30 days Fertilizer.

Preferably, in the step B,

The bacterium song includes following parts by weight ingredient: 8-10 parts of Bacillus subtillis, 1-2 parts and aspergillus oryzae 1-3 parts of saccharomycete.

Preferably, in the step B, material per ton matches 3-5 kilograms of bacterium song, per kilogram bacterium Qu Zhonghan hundred million withered grass buds of 2-5 Spore bacillus.

Preferably, 3-4 meters of the bottom width of band is 1.5-2.0 meters of top width, 1.8-2.0 meters high.

The present invention also provides a kind of equipment for producing high buffer capacity organic fertilizer, in the heap body bottom of ribbon compost Interior to be equipped with ventilation duct, the ventilation duct is connected by tracheae with air compressor, is arranged at intervals with venthole on the ventilation duct. It is supplied gas by air compressor high pressure, forced exhaust.

Preferably, two ventilation ducts are set inside each strip compost, and the venthole is set at the top of tracheae.

Preferably, 100 millimeters of ventilation duct caliber, every rice grain pattern air hose have 30 10 millimeters of venthole.

The present invention also provides the application of high buffer capacity organic fertilizer, which is 120-160 kgs/acre, often Year application is primary.

Beneficial effects of the present invention: applicant is by studying the method for production of high buffer capacity organic fertilizer a kind of, Jing Shinian 56 sample surveys show that organic materials is fermented and are converted into a kind of high buffer capacity organic fertilizer, are matched with organic materials, crop Stalk accounts for 35-40%, filter mud of sugar refinery accounts for 35-40%, animal wastes account for 15-20% and rice bran accounts for the organic fertilizer buffer capacity of 5% acquisition Highest, organic fertilizer Acid and base buffering capacity are respectively 330.1mmol/kg and 109.2mmol/kg.
