According to the remediation agent, the soil can be conditioned, the activity of microorganisms in the soil can be activated, soil caking can be overcome, the air permeability of the soil can be increased, the soil fertility can be enhanced, food crops, economic crops, vegetables, melons and fruits can be greatly increased, the environment pollution can be reduced, and the soil remediation agent is safe and non-toxic to human, livestock and environment, and is environment-friendly.
Description
Technical field
The present invention relates to environmental protection technical field, particularly relate to a kind of soil physics function of can stablizing, improve and balance, can effectively overcome renovation agent of soil compaction and rehabilitating soil and preparation method thereof.
Background technology
Agricultural, because of a large amount of use chemical fertilizer, cause soil compaction, and this phenomenon is more and more serious.In China, mainly 4 kinds of methods are adopted to the prevention of soil compaction and reparation at present:
One is applying organic manure.Applying organic manure, as pig cow dung, not only can improve Soil structure, strengthens the performance of soil fertilizer, ventilative, temperature adjustment, and can improve soil organic matter content, strengthen soil and store fertile performance and the surge capability to soda acid, keep soil from packing together.
Two is straw-returnings.Agricultural crop straw is original organic fertilizer resource, and straw chopping and returning can improve soil organic matter content, increases soil porosity, coordinate the liquid manure gas heat in soil, for soil microbial activity is created a favorable environment, be conducive to organic matter decomposition, soften, improve soil physical and chemical property.
Three is appropriateness deep ploughings.When the subsoiling degree of depth is greater than 30 centimetres, can plough sole be broken, thicken soil thickness, improve topsoil structure, thus keep soil from packing together.
Four is survey soil to implement soil improvement agent.According to soil test result Formulation Implementation soil improvement agent, be combined with inorganic phase by organic, accomplish that nutritional deficiency mends element, carry out soil remediation.
Summary of the invention
Object of the present invention is just for the deficiencies in the prior art, provides another kind can stablize, improve and balance soil physics function, can effectively overcome renovation agent of soil compaction and rehabilitating soil and preparation method thereof.Renovation agent of the present invention can nurse one's health soil, activation Soil Microorganism enlivens rate, overcomes soil compaction, increase soil air permeability, increase soil fertility, food crop, cash crop, greengrocery, melon and fruit class are significantly increased production, it can reduce environmental pollution, to people, animal, environmental safety, nontoxic, it is a kind of soil-repairing agent of environment-friendly type.
