Comprehensive method for soil conditioning and restoration

Abstract

The invention provides a comprehensive method for soil conditioning and restoration. The method comprises the following steps: before crops are planted or after fruit trees are harvested, oyster shellpowder, silicon-calcium-potassium-magnesium fertilizer, biological organic fertilizer, a biological control agent and ternary compound fertilizer are applied to soil; before the fruit trees are sprouted and bloomed, a macroelement water-soluble fertilizer and humic acid water-soluble fertilizer are applied to the soil; during a swelling period of young fruits of the fruit trees, silicon-calcium-potassium-magnesium fertilizer and a composite microbial bacterial liquid are applied to the soil; and during a fruit strengthening period of the fruit trees, high-potassium fertilizer and seaweed fertilizer are applied to the soil. The method is used for conditioning and restoring the soil, so that the pH of the soil tends to be neutral, and the acidification degree is obviously reduced; the organic matter content of the soil is obviously increased, the soil becomes loose and breathable, and the soil layer is deep and thick; and the heavy metal content in the soil is reduced, so that securityof the planted crops is improved, and the yield is improved. The method provided by the invention does not interrupt growth of the crops in the soil, enables the crops to grow healthily while conditioning and restoring the soil, and improves quality of the crops, so that economic benefits of growers are guaranteed.

Description

technical field [0001] The invention relates to a comprehensive method for soil conditioning and restoration, in particular to a comprehensive method for soil conditioning and restoration without affecting the planting of soil crops and improving crop quality, and belongs to the technical field of soil restoration. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals, animals and plants from weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. Soil is the core medium of the environment, an indispensable renewable resource, and an important medium condition for the survival of human beings and many organisms. The quality of the...

Problems solved by technology

For example, aggravating soil compaction makes it difficult for the root system to stretch, weak rooting force, difficulty in slowing down seedlings, easy to form old young trees, old stiff seedlings, poor root development and reduced absorption function, weak growth, and reduced yield; aggravating the waste of pesticides, weakening plant growth, Reduced disease resistance, easy to be infected by diseases, had to increase the amount of spraying; reduce the absorption and utilization rate of some medium and trace elements, resulting in increased investment and greatly reduced benefits; make crops malnourished and serious deficiencies, such as apples Bitter pit disease, pear iron head disease, mango black heart disease, etc. occur frequently; lead to changes in the beneficial microbial populations in the soil, the individual growth of bacteria becomes smaller, and the growth and reproduction speed decreases, such as the main microbial groups that decompose organic matter and its proteins. Bacillus, actinomycetes , Methanogenus and related fungi decrease, affecting the virtuous cycle of nutrient elements, resulting in reduced agricultural production; resulting in increased heavy metal content and activity in the soil, so that the crops grown on the soil have great food safety

Therefore, in the pursuit of green, healthy, and environmentally friendly, it is necessary to develop an efficient soil conditioning and restoration method that can meet the needs of continued crop growth and avoid the disadvantages of certain physical, chemical, biological, and electrolytic methods, such as chemical methods. It is easy to cause secondary pollution, the electrolytic method takes a long time, affects the soil ecology, the biological method has a slow rate, a long cycle and strict requirements on the soil environment, etc.
