Abstract
The invention discloses a special slow-release fertilizer with low cost for rice. The special slow-release fertilizer comprises the following raw materials in parts by weight: 60 to 80 parts of ammonium hydrogen carbonate, 20 to 35 parts of a defluorinated phosphorus fertilizer, 10 to 30 parts of a magnesium-potassium sulfate fertilizer, 1 to 2 parts of microcrystalline cellulose, 1 to 2 parts ofsepiolite powder, 2 to 4 parts of fruit shell carbon powder, 1 to 2 parts of calcium chloride, 1 to 2 parts of mica powder, 1 to 2 parts of sodium-based bentonite, 15 to 45 parts of wormcast, 4 to 18parts of alfalfa powder, 15 to 35 parts of biogas residue, 2 to 4 parts of Gorgon fruit powder, 1 to 2 parts of sodium silicate, 0.2 to 1 part of EDTA chelated zinc, 0.2 to 1 part of EDTA chelated manganese, 1 to 2 parts of diethyl aminoethyl hexanoate, 1 to 3 parts of corn oil and 2 to 4 parts of lignin fiber. The special slow-release fertilizer provided by the invention enables nutrient absorption of the rice to be more comprehensive and balanced, enhances the quality and yield of the rice, improves physical and chemical properties of soil at the same time, fosters soil fertility, can meet the nutrient demands of the rice in the whole growth period, and has the advantages of conservation of labor and time, high fertilizer utilization rate, etc.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer specially used for rice with low cost. Background technique [0002] The content of nitrogen, phosphorus and potassium is the most important indicator of fertilizer efficiency. According to the current fertilization technology, about 60% of the fertilizer applied to the ground is lost or fixed by the soil, polluting groundwater or becoming invalid fertilizer. Unreasonable fertilization methods cause varying degrees of damage to soil, environment, and crops. In recent years, for rice cultivation, some slow and controlled release fertilizers have appeared, which can slow down the release of active ingredients in the fertilizer and reduce the loss of active ingredients, but the coating material is not easy to degrade and the cost is high. Contents of the invention [0003] Based on the technical problems in the background technology, the present inve...
