Abstract

The invention discloses an improved saline-alkali soil type bio-organic compound fertilizer and a preparation method thereof, and belongs to the technical field of fertilizers. The bio-organic compound fertilizer is prepared from beer wastewater treatment station sludge, weathered coal, agricultural production wastes, trace elements, zinc ion-porphyrin nanocomplex, vermiculite powder, livestock manure biogas slurry, a compound microbial agent, humic acid, edible fungus residue and polycaprolactone according to a certain weight ratio. The bio-organic compound fertilizer is suitable for medium-light saline-alkali soil, can significantly reduce the content of alkali and salt in soil, significantly improve physical and chemical properties of soil, improve soil granular structure, alleviate soil hardening problem and improve soil permeability and water and fertilizer retention, improves utilization rate, and significantly increases the yield and income of crops.

Description

technical field [0001] The invention relates to a bio-organic compound fertilizer, in particular to an improved saline-alkali land-type bio-organic compound fertilizer and a preparation method thereof. Background technique [0002] Saline-alkali land means that the land is affected by natural or human factors, causing salt substances to gradually penetrate into the soil, so that the soil contains more salt and alkali, and makes this type of land unusable. The saline-alkali land in my country is roughly distributed in the Northwest, Northeast, North China and coastal areas. The main reason for the formation of saline-alkali land is that the land in relatively arid areas is evaporated into water vapor and discharged into the air, but the salt in the water cannot Excluded and left in the soil, after a long period of accumulation, the salt in the soil gradually increases, thus forming a saline-alkali land. Because the saline-alkali soil itself contains too much salt, according t...
