Problems solved by technology

[0004] 1. Water pressure spraying from deep underground wells not only causes a lot of waste of cost and endangers the safety of groundwater, but also is very easy to repeat, which can only treat the symptoms but not the root cause
[0005] 2. Relying on organic matter improvement, the effect is poor
Large investment, poor effect
In compacted and salinized land, the soil texture is dense, the combination is firm, and t

Embodiment 1

[0030] A culture of microorganisms that improve soil salinization, including Lactobacillus acidophilus, Candida utilis, Rhodopseudomonas palustris, Lactobacillus acidophilus, Candida utilis, Rhodopseudomonas palustris Scale The prepared fermented yeast liquid is inoculated in the fermentation substrate prepared in proportion by corn, soybean meal, bran and molasses to carry out the microbial culture obtained by anaerobic fermentation. Lactobacillus acidophilus, Candida utilis, and Rhodopseudomonas palustris can produce a variety of decomposing enzymes, which can consume the C-chain and N-chain in fertilizer compound salts to reduce them from large molecules to small molecules or ions, and can synthesize A variety of nutrients are supplied to the root system of crops, which can produce antibacterial substances to inhibit and destroy pathogenic bacteria in the soil. The bacteria can grow rapidly in a compact and anoxic environment without producing toxic and harmful substances, p...

Abstract

The invention discloses a microbial culture capable of improving soil salinization. The microbial culture is obtained by inoculating a fermentation substrate prepared from corn, soybean meal, wheat bran and molasses in proportion with fermentation mother liquor prepared from lactobacillus acidophilus, candida utilis and rhodopseudomonas palustris for anaerobic fermentation. The invention further discloses a preparation method of the microbial culture capable of improving soil salinization. The microbial culture has high flora activity, is suitable for breeding and releasing large quantities of organic acids and bacteriocin in saline soil and has the characteristics of good improvement effect and long effect duration. The strain conforms to national relevant regulations, is safe and environment-friendly and is a novel soil salinization improvement scheme which is free of poison, residues and resistance, easy to operate and low in investment.

Description

technical field [0001] The invention belongs to the technical field of biological treatment of salinized soil, in particular to a microbial culture for improving soil salinization and a preparation method thereof. Background technique [0002] With the continuous application of chemical fertilizers for more than 30 years in agricultural land in my country, coupled with the lack of crop rotation conditioning, excessive chemical fertilizers are deposited in the soil, forming strong compounds or polymers that cannot be absorbed by crop roots, and gradually form chemical salt crystals , resulting in soil compaction and increased salinization. [0003] In order to one-sidedly pursue production, growers blindly increase the application of chemical fertilizers, which makes the area of ​​salinized soil accumulate larger and larger, and has basically covered all the territory of China's cultivated land, especially in fruit trees, vegetables, rice, cotton and other planting areas. The...
