Abstract

The invention discloses a improver for soda saline-alkali dry field soil and a preparation method thereof. The improver for soda saline-alkali dry field soil includes the following raw materials: blocking agent, acid regulator, organic fertilizer and microbial bacterial agent. The beneficial effects of the present invention are: the improvement agent of the present invention for soda saline-alkali dry field soil uses microorganisms and quasi-nanometer materials as the raw materials of the improvement agent, and effectively exerts the ecological improvement mechanism of the microbial halophilic and alkali-resistant fungal flora to the soil, through The integrated effect of halophilic and alkali-tolerant Aspergillus, nano-nano-nano-scale inert physical materials, and soil organic residues such as straw has made a breakthrough in solving the problem that most beneficial filamentous fungi are difficult to survive in saline-alkali soil, and the saline-alkali soil is seriously lacking fungi. Thereby improving soil texture, increasing soil organic nutrients, activating soil vitality, restoring soil ecology, and finally achieving the purpose of accelerating the ripening of the plow layer, inhibiting the recurrence of saline-alkali soil, and achieving the goal of radically eradicating saline-alkali land.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an improver for dry field soil in soda saline-alkali land and a preparation method thereof. Background technique [0002] There are more than 99 million hectares of saline-alkali land in my country. Most of the formation of alkaline soil and alkalized soil in China is related to the accumulation of carbonate in the soil. Therefore, the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. Soda saline-alkali soil is a typical agricultural barrier soil. The soil salinity is mainly sodium carbonate and sodium bicarbonate. The pH value is as high as 8.5, and the severe area exceeds 10.5. Due to the large amount of water-soluble sodium ions in the soil, the soil particles are dispersed in the soil solution. In the process, the physical properties of the soil deteriorate, especially the alkalized deposit layer is impermeabl...
