Abstract
The invention relates to the technical field of soil modification and specifically relates to a co-treatment method for soil salinization. The co-treatment method for soil salinization is characterized by comprising the steps of mixing crushed straws or tree leaves or hay with halophilic bacteria in powder, blending with a synergist, thoroughly mixing the straws or the tree leaves or the hay, the halophilic bacteria in powder and the synergist in a certain mixing ratio according to an application amount, evenly spreading the mixture onto the surface of the plowed field, and plowing the soil again after spreading so that the straws or the tree leaves or the hay, the halophilic bacteria in powder and the synergist can be thoroughly mixed with the soil. Compared with the prior art, co-treatment is realized by use of a biological method and a physical method, and the halophilic bacteria are applied to the salinized soil to oxidize and decompose salt in the soil by use of the biological characteristics of the halophilic bacteria, and consequently, the soil salinization degree can be reduced.
Description
Technical field
The present invention relates to soil improvement technical field, specifically a kind of mixed processing method of the soil salinization.
Background technology
The salinity that the soil salinization refers to soil bottom or underground water with Investigation of Upward Movement of Soil Water to earth's surface, after moisture evaporation, make the process of salt accumulation in topsoil, refer to that ease of solubility salinity is in phenomenon or the process of upper soll layer accumulation, also claim salinization of soil, having a very wide distribution of China's salinized soil or title saline-alkali soil, area is large, type is many, approximately 100,000,000 hectares of the gross areas, mainly occur in arid, semiarid and subhumid regions, the soluble-salt of saline-alkali soil mainly comprises sodium, potassium, calcium, the sulfate of magnesium etc., chloride, carbonate and heavy carbonate, sulfate and chloride are generally neutral salt, carbonate and heavy carbonate are basic salt.
Large due to the having a very wide distribution of China's saline-alkali soil, area, cause cultivated area increasingly to reduce, therefore, saline-alkali soil is developed to the soil that can be used for plantation and becomes more and more important.
Summary of the invention
The present invention, for overcoming the deficiencies in the prior art, by physics and biological mixed method, improves the soil salinization, increases soil fertility, thereby for plant growth provides good soil environment, reaches the object of improving agricultural production and ecological environment.
For achieving the above object, design a kind of mixed processing method of the soil salinization, it is characterized in that: the stalk after pulverizing or leaf or hay are mixed with Halophiles bacterium powder, and admix synergist, by certain amount of application mixing ratio mode, stalk or leaf or hay, Halophiles bacterium powder and synergist are fully mixed, be sprinkling upon uniformly the ground surface of turning over, and after having spread, again soil is turned over, stalk or leaf or hay, Halophiles bacterium powder and synergist are fully mixed with soil.
The amount of application of described stalk or leaf or hay is 6 ~ 7.5 tons of per hectares.
Described synergist is by machine matter, ardealite, urea and Clay composition, and the percentage by weight of machine matter, ardealite, urea and clay is that machine matter is 40% ~ 45%, and ardealite is 10% ~ 15%, and urea is 30% ~ 35%, and clay is 5% ~ 20%.
Described stalk is by drying, and the control water yield is at 5% ~ 10% stalk.
Described leaf is by drying, and the control water yield is at 5% ~ 10% leaf.
The sun-proof film of one deck is laid on the upper strata of the saliferous soil after mixed processing.
The present invention compared with the existing technology, carries out mixed processing by the method for biology and physics, utilizes the biological characteristics of Halophiles, uses Halophiles in salinization soil, and the salinity in oxidation Decomposition soil can reduce the degree of the soil salinization.
Meanwhile, the collocation in conjunction with stalk or leaf or hay and synergist, has effectively utilized agricultural wastes, and it is turned waste into wealth; And increase synergist, can accelerate to reduce salinity, the pH value of salinization soil, improves soil texture, improves soil aeration, water permeable ability, for follow-up a large amount of Planting Crops are carried out sufficient preparation.
