Abstract

The invention discloses a microbial agent for saline-alkali soil improvement. The microbial agent is composed of the components in parts by mass: 10%-35% of microbial bacteria, 20%-60% of an adsorbentand 20%-40% of phosphogypsum; the microbial bacteria comprise the components in percentage by mass: 15%-25% of pseudomonas, 20%-30% of bacillus subtilis, 10%-25% of bacillus megatherium, 15%-25% of providencia rettgeri, and 5%-15% of saccharomycetes; the microbial bacteria and ardealite are combined for use, dissolution and release of insoluble phosphate and solidified potassium can be accelerated, the content of available phosphorus, potassium and nitrogen in soil is increased for plants to absorb, and meanwhile the salinity and alkalinity of the soil are reduced.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a microbial agent for saline-alkali land improvement and a preparation method thereof. Background technique [0002] Saline-alkali soil is an important problem of soil degradation, which is harmful to the ecological environment and the sustainable development of agriculture. Improving and reusing saline-alkali soil is one of the major issues in the world. With the rapid growth of the world population, the relationship between soil degradation and food demand The contradiction between the two is becoming more and more prominent. Microbial remediation integrates economic, environmental and ecological benefits, and its application in saline-alkali land improvement has been continuously strengthened in recent years. A large number of studies have shown that microbial agents can activate and promote the absorption of nutrients by plants, produce a variety of physiolo...
