High-efficiency organic fertilizer for vegetables in greenhouses and preparation method of high-efficiency organic fertilizer

Abstract

The invention relates to a high-efficiency organic fertilizer for vegetables in greenhouses and a preparation method of the high-efficiency organic fertilizer, and belongs to the technical field of the fertilizer. The high-efficiency organic fertilizer for the vegetables in the greenhouses is prepared from raw materials in parts by weight as follows: 22-30 parts of hare manure, 25-40 parts of pigeon's excrement, 12-20 parts of sheep manure, 5-10 parts of wormcast, 11-25 parts of grass carbon, 3-7 parts of snail shells, 8-12 parts of egg shells, 3-5 parts of cicada slough, 10-15 parts of rapeseed meal, 10-15 parts of soya bean meal, 25-40 parts of medical stone, 12-20 parts of pumice and 12-20 parts of zeolite. The high-efficiency organic fertilizer for the vegetables in the greenhouses is prepared from natural materials with certain method, does not contain toxic constituents, contains plenty of nutrient elements and minerals required by vegetable growth, can increase and update soil organic matters, promote microorganism reproduction and improve the physical and chemical properties and the biological activity of soil, thereby improving the soil.

Description

technical field [0001] The invention relates to a high-efficiency organic fertilizer for greenhouse vegetables and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Organic fertilizers are carbon-containing materials mainly derived from plants and (or) animals, and applied to the soil to provide plant nutrition as its main function. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green foo...
