Water retention and slow-release fertilizer for corns and preparation method of water retention and slow-release fertilizer

Abstract

The invention discloses a water retention and slow-release fertilizer for corns and a preparation method of the water retention and slow-release fertilizer. The water retention and slow-release fertilizer comprises the following components in parts by weight: 35-40 parts of kitchen wastes, 2-4 parts of melamine, 1.5-2.0 parts of epoxy chloropropane, 3-5 parts of magnesium chloride, 10-12 parts of calcium chloride, 3-5 parts of carboxymethyl starch, 2-3 parts of titanium dioxide, 6-8 parts of silicon dioxide, 17-20 parts of soil nutrient, 30-40 parts of soybean flour, 1-3 parts of aluminum nitride powder, 2-4 parts of ammonium molybdate, 1-2 parts of zinc sulfate, 1-2 parts of manganese sulfate, 4-6 parts of beet pulp, 6-8 parts of orange residues, 8-10 parts of grape roots, 3-5 parts of lotus leaves and 8-10 parts of cucumber stems. Due to the addition of the soil nutrient, the slow-release fertilizer disclosed by the invention not only can be used for effectively improving and fertilizing the soil, increasing the content of organic matters in the soil, reducing the volume weight of the soil and improving the water and fertilizer retention capacity of the soil, but also is relatively high in utilization ratio of nutrients, capable of relatively comprehensively and equally supplying nutrients to corns, remarkably increasing the yield of corns and improving the quality of corns, and remarkable in economic benefit.

Description

technical field [0001] The invention relates to a corn water-retaining slow-release fertilizer and a preparation method thereof, belonging to the technical field of fertilizer manufacturing. Background technique [0002] Ordinary fertilizers have a short period of effectiveness, unreasonable nutrient distribution ratio, unscientific and unbalanced nutrient supply, especially the contradiction of nitrogen fertilizer is more prominent; for the production and cultivation of spring corn, ordinary fertilizers have a short period of effectiveness, and nutrients in fertilizers, especially nitrogen Nutrient release is inconsistent with the demand for nutrients in different growth stages of corn. Due to the concentrated release of nutrients or the uncoordinated release ratio of nutrients, the utilization rate of fertilizers is low, which creates nutrient stress on the growth environment of corn. It is released when corn does not require a large amount of nutrients. A large amount o...

[0002] Ordinary fertilizers have a short period of effectiveness, unreasonable nutrient distribution ratio, unscientific and unbalanced nutrient supply, especially the contradiction of nitrogen fertilizer is more prominent; for the production and cultivation of spring corn, ordinary fertilizers have a short period of effectiveness, and nutrients in fertilizers, especially nitrogen Nutrient release is inconsistent with the demand for nutrients in different growth stages of corn. Due to the concentrated release of nutrients or the uncoordinated release ratio of nutrients, the utilization rate of fertilizers is low, which creates nutrient stress on the growth environment of corn. It is released when corn does not require a large amount of nutrients. A large amount of nutrients enter the soil, but there is not enough nutrient supply when the corn needs a lot of nutrients, so it will cause nutrient stress to the growth of corn, which will seriously affect the quality of corn kernels and pollute the agricultural ecological environment
