Abstract

The invention discloses an improver in allusion to soda saline-alkaline dry land soil and a preparation method thereof. The improver for the soda saline-alkaline dry land soil comprises the followingraw materials: a blocker, an acid regulator, an organic fertilizer, and a microbial agent. The beneficial effect is as follows: the improver in allusion to the soda saline-alkaline dry land soil is capable of selecting a microorganism and a quasi-nano material as raw materials of the improver, efficiently developing an ecological improvement mechanism of a microorganism halophilic alkali-resistingfungal flora to the soil, and through the integration effect of a halophilic alkali-resisting aspergillus flora, a nano-grade and quasi-nano-grade inert physical material and soil organic residues ofstraw and the like, breakthrough-solving a problem that most of beneficial filamentous fungi are difficult to survive in saline-alkali land soil and the saline-alkali land soil is seriously lack of fungi, thereby improving soil texture, increasing soil organic nutrients, activating soil vitality, and repairing soil ecology, and finally achieving a purpose of accelerating ripening of a plowing layer, inhibiting saline-alkali repetition, and fundamentally treating a 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...
