Problems solved by technology

However, physical improvement, water conservancy improvement and biological improvement can only temporarily improve alkaline soil, and have little impact on the growth and yield of crops. However, most of the current chemical improvements will cause heavy metals and harmful traces in the improved soil. Excessive elements will also affect the growth of crops

Abstract

The invention provides a microbial improver for alkaline soil and a preparation method thereof. The microbial improver comprises, by weight parts, 30-40 parts of superphosphate, 20-30 parts of ammonium sulfate, 17-23 parts of potassium sulfate, 6-10 parts of compound microbial agents, 4-6 parts of lignin iron, 2-3 parts of magnesium citrate, 2-3 parts of manganese sulfate, 1-2 parts of wood vinegar and 0.4-0.6 part of zinc sulfate. The microbial improver for the alkaline soil can effectively overcome the imbalance of nutrients in the soil, improve soil properties, loosen the soil, improve thesoil fertility, and gradually improve the soil alkalization phenomenon.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a microbial modifier for alkaline soil and a preparation method thereof. Background technique [0002] Soil acidity and alkalinity are the basic characteristics of soil and one of the important factors affecting soil fertility. The use of fertilizers has an inseparable relationship with the properties of the soil. There are various substances in the soil water solution, referred to as soil solution for short. In the soil solution, there are minerals such as calcium, magnesium, potassium, sodium, ammonium and other nitrates, carbonates, chlorides, sulfates and phosphates, as well as gases such as oxygen, nitrogen and carbon dioxide, and a small amount of soluble protein and sugar. Organic substances such as amino acids, amino acids, etc., because so many substances are dissolved in the soil solution, different soils are acidic and alkaline due to the types and quan...
