Abstract

The invention discloses a sustained release biological medicinal fertilizer, and belongs to the field of fertilizers. The sustained release biological medicinal fertilizer is prepared by taking 5-10 parts of borax, 6-13 parts of triadimenol and 7-15 parts of organosilicone polyoxyethylene ether compound, mixing, pulverizing, screening by a 100-mesh sieve, collecting a sieved particle, extruding, and pelletizing to obtain a medicine particle; taking 25-40 parts of urea, 10-20 parts of potassium chloride, 15-20 parts of zinc chloride, 30-45 parts of polyaspartic acid, mixing, pulverizing, screening by the 100-mesh sieve, collecting a sieved particle, extruding, and pelletizing to obtain a fertilizer particle; taking 5-12 parts of hyaluronic acid, 6-10 parts of polyacrylamide, and 5-12 partsof ethylene-vinyl acetate copolymer, stirring and mixing evenly for 20-30 minutes, adding 12-18 parts of sodium secondary alkyl sulfonate, 6-12 parts of sodium dodecylbenzene sulfonate and 20-30 partsof water, stirring for 15-20 minutes to obtain a compound coating emulsion; taking 5-10 parts of white gourd extract, 5-10 parts of medicine particle and 30-40 parts of fertilizer particle, mixing evenly, spraying the compound coating emulsion, drying to obtain the sustained release biological medicinal fertilizer. The sustained release biological medicinal fertilizer solves the problems that theexpiration date of the medicinal fertilizer is short at present and the too long expiration date causes reduced medicinal effect or failure.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a slow-release biomedical fertilizer. Background technique [0002] Biomedical fertilizer is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a certain proportion through biotechnology, and stabilizing fertilizers and pesticides in a specific compound system through certain technology. Generally, fertilizers are used as pesticides. carrier. For the sustainable development of contemporary agriculture, medicinal fertilizer is a new attempt for modern agriculture supported and driven by powerful technology. Medicinal fertilizer can combine two operation steps in the field into one, which not only saves labor, but also reduces time and energy consumption. In the past hundred years, agricultural production has relied too much on chemical fertilizers and pesticides. The abuse of chemical fertilizers has caused a large amount of waste of non-renewa...
