Straw fertilizer for improving fertilizer efficiency of soil

Abstract

The invention discloses straw fertilizer for improving the fertilizer efficiency of soil. The straw fertilizer is prepared from the following raw materials in parts by weight: 20 to 40 parts of sodium nitrate, 15 to 35 parts of ammonia water, 25 to 35 parts of potassium magnesium sulfate fertilizer, 2 to 6 parts of dolomite powder, 2 to 6 parts of ammonium ferrous sulfate, 1 to 3 parts of sodium silicate, 1 to 2 parts of manganese chloride, 15 to 35 parts of chicken manure, 15 to 35 parts of crop straw, 10 to 30 parts of cassava residue, 15 to 25 parts of cottonseed cake, 40 to 80 parts of mushroom residue, 10 to 20 parts of kelp residue, 15 to 35 parts of oil residue, 6 to 14 parts of a gelatin carbonized wood flour compound, 2 to 6 parts of activated carbon, 2 to 7 parts of glutinous rice flour, 1 to 4 parts of sepiolite powder, 0.5 to 2.5 parts of bentonite, 0.5 to 2.5 parts of soybean lecithin, 0.1 to 0.5 part of compound bacteria and 2 to 4 parts of a film coating agent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a straw fertilizer for improving soil fertilizer efficiency. Background technique [0002] Crops are highly dependent on chemical fertilizers and pesticides, and the agricultural ecological environment is deteriorating. After chemical fertilizers are applied to farmland, the actual utilization rate is only 30% on average. Most of them flow into rivers and lakes with farmland drainage or remain in soil, plants and crops, which not only brings Environmental pollution, as well as endangering the safety and health of human beings and lives, have become obstacles to the sustainable development of agriculture. At present, the utilization rate of various plant straws, especially crop straws, is not high, and the waste is serious. Straws are simply crushed and then directly returned to the field. Because of their slow natural degradation rate, they cannot better make the soil obtain ...

[0002] Crops are highly dependent on chemical fertilizers and pesticides, and the agricultural ecological environment is deteriorating. After chemical fertilizers are applied to farmland, the actual utilization rate is only 30% on average. Most of them flow into rivers and lakes with farmland drainage or remain in soil, plants and crops, which not only brings Environmental pollution, and endangering the safety and health of human beings and life, these have become obstacles to the sustainable development of agriculture

At present, the utilization rate of various plant straws, especially crop straws, is not high, and the waste is serious. Straws are simply crushed and then directly returned to the field. Because of their slow natural degradation rate, they cannot better make the soil obtain higher fertilizer efficiency. and fertility, can not better improve the soil structure
