Green soil remediation method

Abstract

The invention provides a green soil remediation method includes the steps: 1) calcining palygorskite PAL, carbon, silver oxide, zinc oxide, praseodymium oxide, cerium oxide and dysprosium oxide to obtain modified PAL powder in the presence of protective gas; 2) fermenting livestock and poultry manure, straw, vegetable leaves, rapeseed cakes, sugarcane peel, the modified PAL powder, lactobacillus acidophilus, streptococcus thermophilus and lactic acid bacteria in the aerobic condition, then heating the system to 75 DEG C or more, carrying out heat treatment, then concentrating, drying and freezing to produce an organic fertilizer; and 3) spraying the organic fertilizer onto the field. The method can make the soil have excellent fertility.

Description

technical field [0001] The invention relates to the field of soil, 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 caused serious damage to its natural ecosystem, damaged soil structure, lack of active trace elements, and imbalanced microbial environment, which ultimately leads to the decline of the quality of agricultural products, poor taste for consumers, and incomplete nutrition. ; The large economic and artificial input of organic fertilizers, the limited application area, the low crop yield and the negative effects of fake organic fertilizers lead to market confusion, all of which have brought a strong impact on the fertilizer industry. Coupled with large-scale complex soil pollution and food safety issues, the sustainable development of the current fertilizer industry has been greatly restricted. It should be pointed out that the long-term u...

[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.
