Abstract

The invention discloses a microbial fertilizer suitable for rapid salt reduction and alkali modification of saline-alkali soil for corns. The microbial fertilizer comprises the following components: acidithiobacillus, aerobic denitrifying bacteria and a bio-organic fertilizer. The main component of the microbial fertilizer is acclimatized sludge; acidithiobacillus and aerobic denitrifying bacteriaare added into sludge to carry out enrichment culture to obtain acclimatized sludge; after the acclimatized sludge, humic acid, rice bran, animal waste and other raw materials are fermented together,the content of organic nutrients in the fertilizer is remarkably increased, the acclimatized sludge is used for saline-alkali soil, various salt in the saline-alkali soil can be promoted to be dissolved in water under the action of water flow, and therefore the salt in the soil is remarkably reduced. Meanwhile, acclimatized sludge is added into the saline-alkali soil as an inoculum to produce acidic substances, so that the alkalinity of the saline-alkali soil is effectively reduced. The saline-alkali soil treated by the microbial fertilizer is high in corn yield, and the effects of rapidly reducing salt and improving alkali of saline-alkali soil can be achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer suitable for rapidly reducing salt and changing alkali in saline-alkali land of corn. Background technique [0002] The fundamental reason for the formation of saline-alkali soil is poor moisture status, so in the early stage of improvement, the focus should be on improving the soil moisture status. Generally, it is carried out in several steps. First, drain and wash salt to reduce the salinity content of the soil; then plant salt-resistant plants to fertilize the soil; finally plant crops. The specific improvement measures are: drainage, irrigation and salt washing, silt improvement, rice planting, fertilizer improvement, land leveling and chemical improvement. [0003] Microbial fertilizers, also known as biological fertilizers, inoculants, or bacterial manures, refer to a type of fertilizer product that uses the life activities of microorganisms as ...
