Abstract

The invention discloses multifunctional compound coated fertilizer with slow release and yield increase effects. The fertilizer is characterized by being prepared from raw materials in parts by weight as follows: 60-65 parts of cottonseed hulls, 12-14 parts of calcium carbonate, 17-19 parts of potassium dihydrogen phosphate, 20-26 parts of urea, 15-18 parts of calcium magnesium phosphate fertilizer, 15-19 parts of potassium chloride, 1-2 parts of borax, 60-66 parts of tobacco powder, 45-48 parts of mushroom bran, 36-39 parts of starch residues, 2-3 parts of ferrous sulfate, 1-2 parts of ammonium molybdate, 16-19 parts of polyethylene, 6-8 parts of an EM microbial agent, 7-9 parts of a soil conditioner and a proper amount of water. Organic matter components such as the calcium magnesium phosphate fertilizer and the tobacco powder or inorganic element fertilizer is added and the plant growth requirement is met; the soil conditioner is added, and the synergistic effect and the effect of promoting plants to absorb nutrients are realized; a coating process is adopted, the slow release effect is good, the fertilizer is applied to farmland once, the activity of soil nitrifying bacteria is inhibited, soil fungi are killed, soil acidification can be avoided, and the crop yield can be increased.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a slow-release and yield-increasing multifunctional composite coated fertilizer and a preparation method thereof. Background technique [0002] At present, my country's agriculture is developing rapidly. my country is not only a big agricultural country, but also a big country in the use of fertilizers. The application and development of fertilizers are getting more and more attention. In order to meet the needs of the development of agricultural modernization, the production of fertilizers is developing in a diversified direction such as high-efficiency compound fertilizers and multi-functional fertilizers. Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, polyethylene and elemental sul...
