Embodiment 1

[0025] A polymeric peptide coated BB fertilizer is made from the following raw materials in percentage by weight:

[0026]

[0027] Its preparation method steps are as follows:

[0028] First, weigh 240kg of urea, 200kg of potassium fertilizer, 250kg of monoammonium phosphate, 300kg of biochemical organic fertilizer, and 10kg of polymerized peptide; put the accurately measured urea, potassium fertilizer, monoammonium phosphate, and biochemical organic fertilizer into the mixer for mixing; The finished fertilizer is put into the coating machine, and then the weighed polymer peptide is sprayed to coat the fertilizer; then the coated fertilizer is put into the dryer for drying, and the drying temperature is 45 ℃ and large air volume for drying; then put the dried fertilizer into the cooler for cooling, and sieve the cooled fertilizer twice to improve the uniformity; finally, measure and pack the treated coated fertilizer and put into warehouse.

Abstract

The invention discloses a polypeptide coated BB fertilizer and a preparation method thereof, relating to the technical field of fertilizer. The polypeptide coated BB fertilizer comprises urea, potash fertilizer, monoammonium phosphate, biochemical organic fertilizer and polypeptide. The preparation method comprises the following steps: preparing materials, mixing, spraying, coating, drying, cooling, sizing, packing and warehousing. According to the invention, the fertilizer provided by the invention can slowly and gradually release active ingredients, the amount of fertilizer is reduced, and the utilization rate is raised, has the advantages of convenient construction, labor saving property and safety, and can improve soil environment and raise the soil loose level.

Description

Technical field: [0001] The invention relates to the technical field of chemical fertilizers, in particular to a polymer peptide-coated BB fertilizer and a preparation method thereof. Background technique: [0002] Chemical fertilizers are widely used in agricultural production. Chemical fertilizers are easily soluble in water and will work immediately after fertilization and be absorbed by crops in a short period of time. Therefore, in each stage of crop growth, it is necessary to apply various fertilizers, such as nitrogen fertilizer, potassium fertilizer, phosphorus fertilizer, ammonium fertilizer, etc. These fertilizers with different functions cannot be applied at one time in advance. In addition, the amount of fertilization should be appropriate, not too much, otherwise it will be detrimental to the growth of crops. In this way, for crops, it will cause uneven fertilizer application, that is, enough fertilizer in the early stage of fertilization, which is more than th...
