Abstract

The invention relates to a saline-alkali soil improving agent and its preparation method. The preparation method comprises the following steps: mixing Rhodopseudomonas palustris, Pichia membranefaciens Hansen bacterium, lactobacillus casei, Staestomyces microflavus and seaweed slurry, organically combining a plurality of beneficial microorganisms and seaweed through multi-time fermentation, culturing in a compound mode to obtain a novel microorganism agent-seaweed bio-fungus. adding a proper amount of humic acid, organic matter, active zeolite powder and molasses, fermenting and drying the fermented product. The saline-alkali soil improving agent uses a plurality of microorganisms and employs strong effects of a unique ionic adsorbent, an organic neutralization balancing agent, an ion-exchange agent and a beneficial bacteria conversion starter to achieve the purposes of improving the soil environment, regulating acid-base balance, reducing the salt content, effectively raising the soil fertility and permeability, loosening the soil, eliminating the soil hardening, degrading the harmful substance and promoting the accumulation and conversion of the organic substance.

Description

technical field [0001] The invention belongs to a microbial fertilizer, in particular to a soil conditioner for improving soil salinity and a preparation method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Soil salinization is a worldwide problem. The area of ​​saline soil in the world is about 1 billion hectares. my country has 99.13 million hectares, or about 1.47 billion mu. More than 100 cities in the country are located in saline-alkali distribution areas. Nearly 500 million mu of land has been lost or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuo...
