Abstract

The invention provides a soil conditioner capable of preventing and treating soil hardening and absorbing heavy metal. The soil conditioner capable of preventing and treating soil hardening and absorbing heavy metal comprises bentonite, zeolite powder, lentinan, Enteromorpha prolifera, diatomite, animal manure, potassium humate, composite amino acid, sodium alginate, brown algae powder, jerusalemartichoke extract product, black fungus polysaccharide, a composite microbial solution, attapulgite, and amino acid chelated calcium. The effective bacterium content of the soil conditioner ranges from 28 to 35*10<9>/g, the pH value ranges from 6.2 to 6.8. The soil conditioner possesses obvious heavy metal absorption effect, is capable of reducing heavy metal content of crops, and increasing cropyield.

Description

technical field [0001] The invention relates to the technical field of soil conditioning, in particular to a soil conditioner for preventing soil compaction and adsorbing heavy metals and a preparation method thereof. Background technique [0002] Soil compaction refers to the lack of organic matter and poor structure of the soil surface. Under the action of external factors such as irrigation or rainfall, the structure is destroyed and the soil material is dispersed. After drying, the soil surface is hardened by the cohesive force. Usually, the pollution to the environment should be reduced. [0003] Soil compaction is a key factor that cannot be ignored. Take small tomatoes grown in sheds as an example. For the same seeds, some villages grow small fruits and the plants do not grow vigorously; on the contrary, some villages grow large, brightly colored, and excellent-tasting fruits. Analyzing many reasons, soil compaction is the chief culprit affecting the product. If you...
