Crop slow-release fertilizer prepared by using edible fungus residue

Abstract

The invention discloses a crop slow-release fertilizer prepared by using edible fungus residue, and relates to the field of crop fertilizers. The crop slow-release fertilizer comprises a slow-releasefertilizer matrix, a slow-release fertilizer coating film and a binder, wherein the slow-release fertilizer matrix comprises the following raw materials in parts by weight: 200-300 parts of bauxite-modified edible fungus residue, 120-180 parts of urea, 70-100 parts of potassium dihydrogen phosphate, 35-55 parts of ammonium chloride, 15-35 parts of ammonium sulfate, 8-16 parts of magnesium aluminosilicate, 40-80 parts of an amino acid compounding agent, 20-45 parts of potassium sulfate, 5-9 parts of ferric chloride, 30-50 parts of soybean meal and 3-7 parts of fulvic acid; and the slow-releasefertilizer coating film comprises the following raw materials in parts by weight: 50-80 parts of polylactic acid, 30-40 parts of starch, 30-50 parts of bamboo fiber compounded polyhydroxybutyrate, 25-30 parts of polypropylene and 6-8 parts of propylene glycol monomethyl ether acetate. The prepared slow-release fertilizer has abundant nutrition and slow release rate, and the slow-release fertilizercoating film can be easily degraded and do not pollute the lands.

Description

Technical field: [0001] The invention relates to the field of crop fertilizers, in particular to a slow-release fertilizer for crops prepared from edible fungus residues. Background technique: [0002] The development of planting in agricultural production is inseparable from fertilizers. my country's agriculture has a long history of 10,000 years. In ancient times, manure was called manure, and fertilization became manure field. Fertilization of farmland in my country began around the Yin and Shang dynasties, mainly based on the unearthed cultural relics that had wooden tools made of river mud at that time, and the oracle bone inscriptions of the Yin and Shang Dynasties that had recorded the characters for feces and choke, and there were inscriptions that fertilization can increase production. By the Warring States period, it had paid attention to and emphasized the fertilization of farmland. In ancient my country, animal manure was used as fertilizer at most. In the Warr...

Problems solved by technology

[0003] "Slow-release" means that the release rate of chemical substances and nutrients is much lower than the release rate of instant fertilizers converted into plant-available nutrients after being applied to the soil. The current slow-release fertilizers are usually filled with fertilizers in a coating film that controls the release rate. However, the release rate is still fast, and the coating film remains in the land to form pollution, which is not easy to degrade, affects the normal use of the land, and reduces the quality of the land
