Abstract

The invention relates to the field of composite fertilizers, and concretely relates to a livestock-plasma-containing production-increased sustained-release composite fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000 mesh diatomite, 23-25 parts of urea, 4-6 parts of quick lime, 5-6 parts of slaked lime, 4-7 parts of magnesia, 1-3 parts of ammonium molybdate, 6-8 parts of polyaspartic acid, 12-15 parts of sodium alginate, 3-5 parts of livestock plasma, 6-8 parts of enteromorpha prolifera dry powder, 15-18 parts of decomposed cattle manure, 12-13 parts of potato residue, 1-3 parts of silicon dioxide, 0.1-0.2 parts of zinc oxide, 0.001-0.002 part of cerium oxide, 5-8 parts of sodium oleate and 4-5 parts of an auxiliary agent. The composite fertilizer is wide in raw material resource, organic materials subjected to fermentation are relatively high in fertilizer efficiency, nutrients are relatively easy to absorb by crops, also the fertilizer is capable of protecting soil environment, a diatomite sustained-release coating agent is utilized in the production technology for forming dual cladding on nutrients, and the composite fertilizer has excellent durable sustained-release control ability. Polyaspartic acid in the composite fertilizer is capable of assisting to improve soil fertility and promote growth of crops during gradual degradation, and the production-increasing output-increasing effects of planted crops are obvious.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a production-increasing slow-release compound fertilizer containing poultry plasma. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilize...
