Composite microorganism multi-element soil conditioning agent

Abstract

The invention discloses a composite microorganism multi-element soil conditioning agent, and provides a composite microorganism soil conditioning agent which is high in activity and rich in bacteria kind, and silicon, calcium and magnesium powder is adopted as a carrier, so that relatively stable function overlapping combination of the bacteria and the carrier can be achieved. The composite microorganism multi-element soil conditioning agent comprises the following main components: silicate bacteria, bacillus subtilis and EM (effective microorganisms) bacteria prepared by using a double-fermentation technique, and silicon, calcium and magnesium powder as the carrier, wherein the silicon, calcium and magnesium powder comprises calcium magnesium silicate (effective silicon), calcium oxide, magnesium oxide, manganese dioxide and the like which are essential for plants to grow; and furthermore lignite, zeolite powder and rice hull powder ash are added. By adopting the composite microorganism multi-element soil conditioning agent disclosed by the invention, the acidity and alkalinity of soil can be regulated, soil hardening can be avoided, aggregated soil structures can be broken, pesticide residues of the soil can be reduced, residues of heavy metals in crops can be reduced, natural minerals of the soil can be supplemented, consumption of chemical fertilizers and pesticides can be reduced, photosynthesis of plants can be increased, root development of the plants can be promoted, the plants can grow healthy and strong, a high fertilizer absorption property can be achieved, and the yield increase and good harvest can be ensured.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to the field of using compound microorganisms to regulate soil multi-element components. Background technique [0002] In today's agricultural production and life, the simple application of traditional nitrogen, phosphorus, and potassium fertilizers is no longer enough to meet the needs of high-yield and high-quality crops. In order to pursue high-yield and high-quality crops, the input of chemical fertilizers is also increasing. Reasonable fertilization will cause soil compaction to become more and more serious, the soil ecological environment will become worse and worse, and the soil elements will become unbalanced, resulting in the loss of natural fertility of the soil. As early as the 1990s, scientists proposed that it is necessary to comprehensively supplement elements in the soil, improve the soil environment, and restore the natural fertility of the soil. Soil conditioners cu...

AI Technical Summary

Problems solved by technology

The current market soil conditioner has three major disadvantages: 1. Simple microbial soil conditioner does not have the function of supplementing trace elements in the soil, which leads to the imbalance of elements in the soil

2. Simple trace element soil conditioner, trace elements are not active, are not easy to be absorbed by crops, and cannot achieve the fundamental purpose of restoring the natural fertility of the soil

3. After microorganisms enter the soil, affected by the natural environment of the soil, they often cannot survive in the soil for a long time
