Problems solved by technology

[0002] Due to the long-term excessive use of chemical fertilizers and pesticides on the land, it has seriously damaged its natural ecosystem, damaged the soil structure, lacked active trace elements, and unbalanced the microbial environment, which eventually led to a decline in the quality of agricultural products, poor taste and incomplete nutrition for consumers. ; Large economic and labor inputs for organic fertilizers, limited application areas, low crop yields, and negative effects brought about by fake organic fertilizers lead to market chaos, all of which have brought a strong impact on the fertilizer industry
Coupled with the large-scale compound pollution of the soil and the food safety problems caused by it, it has greatly limited the sustainable development of the current fertilizer industry.
What needs to be pointed out is that the long-term use of fertilizers makes the soil easy to harden, which is not conducive to the growth of crops.

Abstract

The invention discloses a green soil repairing method, comprising: 1) calcining palygorskite PAL, carbon, silver oxide, zinc oxide, praseodymium oxide, cerium oxide and dysprosium oxide in the presence of shielding gas to obtain modified PAL powder; 2) fermenting livestock manure, straw, vegetable leaves, rapeseed cake, sugar cane skin, the modified PAL powder, lactobacillus acidophilus, streptococcus thermophilus and lactic acid bacteria under an aerobic condition, and then heating a system to 75 DEG C or higher for heat treatment, and then concentrating, drying, and freezing to obtain organic fertilizer; 3) applying the organic fertilizer to a farm land. The method not only can make soil have excellent fertility but also can relieve soil hardening.

Description

technical field [0001] The invention relates to the soil field, in particular to a green soil restoration method. Background technique [0002] Due to the long-term excessive use of chemical fertilizers and pesticides on the land, it has seriously damaged its natural ecosystem, damaged the soil structure, lacked active trace elements, and unbalanced the microbial environment, which eventually led to a decline in the quality of agricultural products, poor taste and incomplete nutrition for consumers. ; Large economic and labor inputs for organic fertilizers, limited application areas, low crop yields, and market chaos caused by the negative effects of fake organic fertilizers have all brought a strong impact on the fertilizer industry. Coupled with the large-scale complex pollution of the soil and the food safety problems caused by it, it has greatly limited the sustainable development of the current fertilizer industry. What needs to be pointed out in particular is that t...
