Problems solved by technology

Some have only one of them, and the function is single; the compound bacteria are only 2-3 strains, and the function is not complete
Its effective active bacteria content is less than 20 million / g, and some of them are not strong enough to resist high temperature, dryness, acid and alkali, and salt. They die in large numbers during fertilizer production or storage, and the survival rate is low. It is difficult to achieve expected effect

Embodiment 1

[0096] The preparation method of multifunctional biological protein controlled-release fertilizer comprises the following process steps:

[0097] A. Organic fertilizer granulation

[0098] According to the proportion of rapeseed cake: feather meal: bone meal: auxiliary material = 25:25:18:18 according to the ratio of mass and number, the above raw materials are mixed and crushed to make granular organic fertilizer, and the auxiliary material is selected from cottonseed cake or straw one or a mixture thereof;

[0099] B. Bacteria preparation

[0100] After rejuvenating and expanding the strains, they are respectively inserted into the fermentation medium for fermentation, and the fermented bacterial liquid is flash-dried to make a bacterial agent. The strains are Bacillus licheniformis CCTCCNO: M2013021, Bacillus subtilis CCTCCNO : M2013019 and Bacillus amyloliquefaciens CCTCC NO: M2013020;

[0101] C. Bacterial film coating

[0102] Mix the bacteria agent prepared in step ...

Embodiment 2

[0129] The difference between this embodiment and embodiment 1 is:

[0130] In step A, according to the proportion of rapeseed cake: feather meal: bone meal: auxiliary material = 35:35:22:22, the above raw materials are mixed and crushed to make granular organic fertilizer, and the auxiliary material is selected from cottonseed cake or One or a mixture of straws;

[0131] The culture temperature in steps B3 and B4 is 29.5°C.

[0132] C. Bacterial film coating

[0133] Mix the bacteria agent made in step B to make a mixed dry bacteria powder, and make a film coating agent according to the ratio of mixed dry bacteria powder: carboxymethyl cellulose: water = 5:0.05:3 according to the ratio of mass and number The ratio of mass and number is the ratio of coating agent: granular organic fertilizer = 8.05: 1000, coating the coating agent on the surface of the granular organic fertilizer prepared in step A, and drying it at 50°C to make bio-organic fertilizer ;

[0134] D. Nitrifi...

Embodiment 3

[0141] The difference between this embodiment and embodiment 1 is:

[0142] In step A, according to the proportion of rapeseed cake: feather meal: bone meal: auxiliary material = 30:30:20:20, the above raw materials are mixed and crushed to make granular organic fertilizer, and the auxiliary material is selected from cottonseed cake or One or a mixture of straws;

[0143] The culture temperature of steps B3 and B4 is 35°C.

[0144] C. Bacterial film coating

[0145] Mix the bacteria agent made in step B to make mixed dry bacteria powder, and make a film coating agent according to the ratio of mixed dry bacteria powder: carboxymethyl cellulose: water = 3:0.04:2 according to the ratio of mass and number The ratio of mass and number is the ratio of film coating agent: granular organic fertilizer = 6:745, coating the film coating agent on the surface of the granular organic fertilizer prepared in step A, and drying it at 45°C to make bio-organic fertilizer ;

Abstract

The invention belongs to preparation of a fertilizer and particularly relates to a preparation method of a multifunctional bioprotein controlled release fertilizer. The preparation method comprises the following process steps of: granulating an organic fertilizer, preparing a fungicide, coating mycoderm, coating a nitrification inhibitor, preparing the bioprotein controlled release fertilizer and the like. The preparation method disclosed by the invention solves the prominent problems that when a biological fertilizer in the prior art and a chemical fertilizer are applied at the same time, strains are easily killed by hyperosmosis generated by the chemical fertilizer, soil are hardened, the fertility is reduced, crop diseases and pest are serious, agricultural output and quality are reduced and the like. The preparation method disclosed by the invention has an advanced production technology and selects high-grade raw materials; the nutrition is comprehensive and the content is high; and the fertilizer has many functions and has the obvious effects of reducing soil activity, fertilizing soil fertility, resisting diseases, increasing the production and improving the quality.

Description

technical field [0001] The invention belongs to the preparation of fertilizers, in particular to a preparation method of a multifunctional biological protein controlled-release fertilizer. Background technique [0002] The robust growth of crops requires fertile soil as a foundation. Fertile soil should not only have abundant nitrogen, phosphorus, potassium and other large, medium and trace inorganic nutrients and organic nutrients, but also have a certain amount of beneficial microbial flora. If it is insufficient or lacking, it needs to be applied in sufficient amount to realize the target yield. [0003] Traditional compound (blended) fertilizers only contain nitrogen, phosphorus, and potassium. Over the years, in the cultivation of crops, the amount of chemical fertilizers has been increasing, while the amount of organic fertilizers has been decreasing. The phenomenon of not cultivating the land is prominent. Excessive application of inorganic chemical fertilizers not o...
