Technical Field

The invention belongs to the field of soil remediation, and particularly relates to a soil conditioner and a soil conditioning method.

Background

Soil remediation is a technical measure to restore normal function to contaminated soil. In the soil remediation industry, the existing soil remediation technologies can be more than one hundred, the common technologies can be more than ten, and the existing soil remediation technologies can be roughly divided into three methods, namely physical methods, chemical methods and biological methods. Many countries in the world, especially developed countries, develop and develop contaminated soil remediation and remediation plans, and therefore an emerging soil remediation industry is formed. Heavy metals are a typical class of remediation objects in the soil remediation industry. Due to the long-term use of chemical fertilizers and pesticides, soil is hardened, the soil has low void degree and poor air and water permeability, the effective microbial biomass in the soil is reduced, the soil activity is poor, the nutrient conversion of plant roots is slow, and the nutrient absorption function is weak. Therefore, the development of high-efficiency soil conditioners, the improvement of soil structures, the increase of microbial biomass in soil and the change of soil activity become problems to be solved urgently in agricultural development.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a soil conditioner and a soil conditioning method, which solve the problems of hardening of the soil, less soil void degree, poorer air and water permeability, reduction of effective microorganism amount in the soil, poorer soil activity, slow nutrient conversion of plant roots and stems and weaker nutrient absorption function in the prior art.

In order to achieve the purpose, the invention provides a soil conditioner which comprises the following substances in percentage by mass: 5-10% of lime powder, 8-15% of manganese fertilizer, 20-30% of red mud, 15-20% of calcium magnesium phosphate fertilizer, 22-28% of peat, 3-8% of sepiolite powder and 5% of humic acid.

Further, adding humic acid into the lime powder and the sepiolite powder in a stirrer, and uniformly stirring; and when the interval is 4 hours, the manganese fertilizer, the red mud, the calcium magnesium phosphate fertilizer and the peat are gradually added and stirred.

Further, the vermiculite is in a powder form, and the mass percent of the vermiculite is not less than 5%.

Accordingly, a method of soil improvement comprising the steps of:

s1, removing stones and other solid wastes in soil,

screening soil by hand or agricultural machine, removing stones, pesticide bottles, batteries, plastic products and waste mulching films,

s2, introducing foreign soil,

removing the seriously polluted soil, replacing the seriously polluted soil with new soil,

s3, deep loosening of the soil,

the soil is deeply loosened by more than 25cm by adopting a rotary cultivator, the hardened soil is broken, more water is preserved in the soil,

s4, applying an organic fertilizer to the mixture,

organic fertilizer is used for improving the content of organic matters in soil, enhancing the adsorption capacity of soil colloid to heavy metals and overcoming inorganic pollution; meanwhile, the microbes in the organic fertilizer are utilized to promote the degradation of harmful substances in the soil and improve the fertility of the soil,

s5, applying a soil conditioner,

the soil conditioner comprises 5-10% of lime powder, 8-15% of manganese fertilizer, 20-30% of red mud, 15-20% of calcium magnesium phosphate fertilizer, 22-28% of peat, 3-8% of sepiolite powder and 5% of humic acid,

s6, irrigating at regular intervals,
