Abstract
The invention relates to the field of compound fertilizers and particularly relates to a slow-release compound fertilizer for enhancing soil fertility. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000-mesh diatomite, 2-3 parts of asarum powder, 6-7 parts of peat soil, 8-10 parts of leaf mould, 3-4 parts of polyglutamic acid, 10-12 parts of bran, 0.001-0.002 part of prohexadione calcium, 6-8 parts of broad bean peel, 12-13 parts of soybean oil manufacturing leftovers, 5-8 parts of triple superphosphate, 22-25 parts of ammonium hydrogen carbonate, 15-18 parts of sulfate of potash-magnesia, 3-5 parts of zinc sulfate heptahydrate, 15-18 parts of composed manure, 2-5 parts of ferrous sulfate, 20-25 parts of diammonium hydrogen phosphate, 1-2 parts of inositol hexaphosphate, 4-5 parts of agarose, 2-3 parts of sodium dodecyl benzene sulfonate (ABS), 15-18 parts of water-based polyurethane emulsion, 1-3 parts of nano-silicon and 4-5 parts of assistant. The compound fertilizer provided by the invention is wide in source of raw materials and rich and polybasic in nutrients, and various green organic matters can adjust the soil structure so as to enhance the fertility. Diatomite and a modified polyurethane slow-release coating agent form a double coating to the nutrients, so that the fertilizer efficiency is more lasting, thus the output and quality of crops are effectively improved.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to a slow-release compound fertilizer for improving soil fertility. 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 fertilizers. However, the e...
