Abstract
The invention discloses chitosan-coated controlled-release fertilizer for wheat and a preparation method of the chitosan-coated controlled-release fertilizer. The chitosan-coated controlled-release fertilizer is prepared from the following raw materials in parts by weight: 30-40 parts of potassium sulfate, 20-30 parts of monopotassium phosphate, 15-25 parts of monoammonium phosphate, 1-6 parts of a conditioner, 20-30 parts of 3% chitosan-coated urea, 10-20 parts of 4% chitosan-coated urea, 10-20 parts of 5% chitosan-coated urea and 25-35 parts of starch-based degradable plastics. The raw materials of the fertilizer integrate the conditioner and the fertilizer, and accordingly, the effect of soil regulation can be realized during release of the controlled-release fertilizer. The chitosan-coated controlled-release fertilizer for the wheat can provide nutrients required for growth of wheat to the greatest extent and can also release soil nutrients in accordance with respective content, the release cycle of the nutrients coordinates with the growth of the wheat, average release of nitrogen, phosphorus and potassium can be effectively guaranteed, and release of the fertilizer can meet the requirements of absorption rate of the wheat, therefore, the quality of the wheat is improved, and the yield of the wheat is increased.
