Abstract
The invention relates to a soil improver, in particular to a soil regulator for promoting the growth of crops and application thereof. The soil regulator comprises the following components: 4-8 parts of chitosan, 50-60 parts of organic substance, 0.02-0.05 part of compost corruption promoter, 10-13 parts of soil biological bactericide, 2-4 parts of 8-12 percent urea solution, 8-10 parts of urea and 19-36 parts of porous inorganic substance. The regulator is used as a fertilizer in the planting process of crops and is applied at one time as a base fertilizer during sowing in spring, and 30-50 kilograms of the regulator is applied in each mu of soil. The soil regulator can obviously improve the physicochemical property of the soil, promote the formation of soil aggregates, and increase the pH value of the soil and the cationic substitution amount of the soil so as to increase the fertility of the soil and the utilization rate of the fertilizer and promote the growth of the crops, and has good ecological and economic benefits.
Description
Technical field
The present invention relates to soil improvement agent, the soil redeposition of specifically a kind of short plant growth and application thereof.
Background technology
Development along with China's economic, the agricultural of China has also obtained significant progress, supported the population that accounts for the world 21% with the arable land that accounts for the world 7%, but, when Chinese agriculture is obtained marked improvement, the usage quantity of China's chemical fertilizer and chemical pesticide is also increasing year by year, the agroecological environment of China progressively worsens, soil erosion, desertification of land and impoverishment, calamitous climate is frequent, soil quality descends to the increasing threat of Chinese agricultural components, in order to improve soil quality, the reinforced soil function, be necessary structure and the fertility attribute of soil are nursed one's health, to reach the promotion plant growth, improve crop yield, to tackle the Food Security of China.
Halobiontic development and utilization is one of the major fields of 21 century resources effective utilization, and wherein the application of chitosan is one of efficient major fields of utilizing of Living marine resources, and there is a large amount of chitosan resources in China.It is found that in recent years chitosan can increase substantially the output of farm crop, improves soil characteristic and structure.Because chitosan is the polymer glycosaminoglycan that extracts from shrimp and crab shells; the application of its related products on agricultural both can improve crop yield; also can improve crop quality; improve soil function, simultaneously all right Promoting plant growth, growth, breeding, diseases prevention and disease-resistant, thereby the amount of application of minimizing chemical pesticide; environment is not caused any pollution yet; the people is free from side effects, when realizing protection of the environment, reaches the purpose that improves land output.
Summary of the invention
Degenerate for present China farmland quality, Soil Fertility Quality descends, the fact of soil function decline, enter biochemical reaction behind the soil according to biological substances such as chitosans, the invention provides a kind of soil improvement agent, be intended to improve Soil Fertility, improve the soil organisms function, reach the promotion plant growth, improve the purpose of crop yield.
For achieving the above object, the technical solution used in the present invention:
A kind of soil redeposition of short plant growth, count by weight, its composition comprises: chitosan 4-8 part, organic 50-60 part, 0.02-0.05 the short rotten agent of part compost, soil organisms microbial inoculum 10-13 part, 2-4 part mass concentration is the 8-12% urea soln, 8-10 part urea and 19-36 part porous, inorganic thing; Soil redeposition is mixed under normal temperature (15 ℃-30 ℃) condition by mentioned component.
The short rotten agent of described compost is one or more in the agent of Fu Erde organic fertilizer fermentation, monarch's moral microbial starter culture, garden, the garden biological organic fertilizer starter; The porous, inorganic thing is one or more in perlite, sepiolite, medical stone, the zeolite; Contain photosynthetic bacterium 4-5 part in the soil organisms microbial inoculum, phosphate solubilizing bacteria 3-4 part, potassium solubilizing bacteria 3-4 part.Described organic matter is that humic acids and organic materials form in normal temperature (15 ℃-30 ℃) lower two weeks of heap fermentation, pulverizing after mixing by weight the ratio for 0.2-0.3; Described humic acid is the peat composed of rotten mosses and/or brown coal; Organic materials be in wooden chaff, peanut cake, the soya-bean cake one or more.
Described conditioning agent is as the fertilizer in the planting process of farm crop, does when sowing the seed in spring that base manure is disposable to be applied, and mu is executed 30-50kg.
Humic acids contains abundant organic carbon, is natural organic matter, and long-term a large amount of uses can obviously improve soil organic matter content, improve Soil structure, improve Water and fertilizer retention ability of soil.Chitosan can activate vegetable cell, strengthens the resistance of plant, promotes the plant absorbing nutrient, improves the quality and yield of farm crop, can improve soil physico-chemical property simultaneously, improves intensity of soil respiration, increases soil microbial biomass.The porous, inorganic thing can increase the absorption property of soil, improves the fertilizer-preserving ability of soil, is conducive to simultaneously the improvement of Soil structure.The interpolation of photosynthetic bacterium can improve the crop photosynthesis, and then improves the output of crop, and the interpolation of P and K decomposing bacterium can promote soil to discharge more phosphorus, potassium, satisfies crop to the demand of phosphorus potassium, has active effect to improving Soil Fertility Quality.The purpose that adds inorganic nitrogenous fertilizer is to reduce the C/N of conditioning agent, accelerates organic decomposition, satisfies the demand of agriculture production.Because chitosan is a kind of polymer glycosaminoglycan, itself contain carbon nitrogen, can provide energy and nitrogen for soil microorganisms, can improve microbial biomass C nitrogen, accelerate the soil microorganisms respiration, the reinforced soil microbial decomposition makes soil discharge more nutrient and absorbs for crop.
In a word, the present invention can obviously improve soil physico-chemical property, promotes soil agreegate to form, improve the acid-basicity of soil, improve the soil cation exchange capacity, and then increase soil fertility and utilization rate of fertilizer, promote plant growth, the ecological benefits that tool is good and careful benefit.
