Compound fertilizer capable of improving soil aeration and preparation method thereof

Abstract

The invention discloses a compound fertilizer capable of improving soil aeration and a preparation method thereof. The compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 2 to 3 parts of stalactite powder, 1.2 to 1.5 parts of sodium carboxymethyl starch, 2.4 to 2.6 parts of glycerin monostearate, 1.2 to 1.4 parts of mannitol, 6 to 7 parts of potassium sulfate, 16 to 18 parts of seaweed meal, 5 to 6 parts of potassium phosphate, 2.8 to 3.2 parts of borax, 1.4 to 1.6 parts of pyrolusite powder, 1.7 to 1.9 parts of zinc sulfate, 4 to 5 parts of humic acid iron, and 2.3 to 2.4 parts of ferric sodium edelate. The compound fertilizer is rich in nutrients, can be absorbed and utilized rapidly, and can improve the crop activity, facilitate metabolism, increase the content of beneficial functional substances, and facilitate growth.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a compound fertilizer capable of improving soil aeration and a preparation method thereof. Background technique [0002] my country is a typical large agricultural country with a large population and little arable land, and chemical fertilizers play a very important role in the production of crops. According to the research, the nitrogen, phosphorus, potassium and other nutrients applied to the soil will undergo various physical and chemical changes, among which nitrogen will be lost through volatilization, leaching, denitrification, etc., and phosphorus is easily absorbed by Al3+ and Fe3+ in the soil. And various ions such as Ca 2+ and Mg2+ are fixed to form stable precipitates or form closed storage phosphorus with iron and aluminum oxides, and gradually lose their effectiveness. These factors will reduce the utilization rate of fertilizer application. The use of chemical f...

Problems solved by technology

According to the research, the nitrogen, phosphorus, potassium and other nutrients applied to the soil will undergo various physical and chemical changes, among which nitrogen will be lost through volatilization, leaching, denitrification, etc., and phosphorus is easily absorbed by Al3+ and Fe3+ in the soil. And various ions such as Ca 2+ and Mg2+ are fixed to form stable precipitates or form closed storage phosphorus with iron and aluminum oxides, and gradually lose their effectiveness

These factors will lead to a reduction in the utilization rate of chemical fertilizers

The use of chemical fertilizers will also cause environmental pollution, such as the greenhouse effect, eutrophication of water bodies, etc.
