Description
Technical field
The present invention relates to saline land processing technology field, particularly relate to the method that the two methylolurea+EDTA+ biological bacteria of a kind of ardealite+1'3-improves saline land.
Background technology
Saline land is the general name of solonchak and alkaline earth and various salinization, alkali-affected soil.Solonchak refers to that in soil, soluble organic fraction content acquires a certain degree, and can produce the great soil group of obviously harm to the g and D of plant.Alkaline earth refers to that quantity reaches the degree that can endanger plant growth and growth containing a large amount of exchangeability ion in soil, and the soil that soil property is changed.In actual state, solonchak and alkaline earth often exist in a mixed way jointly, are referred to as saline land.
Saline land is important land resources, and it is a kind of soil types of extensively distribution on the earth.About nearly 1,000,000,000 hectares of whole world saline soil area, China's Resource of Saline Soil is distributed widely in 17 provinces and regions based on the north, the main integrated distribution region of northwest, northeast, North China and coastal Deng Shi China saline soil, the gross area reaches more than 500,000,000 mus, and account for that the whole nation can utilize land area nearly 5%.The wherein gross area in Coastal beach saline land about 2,350,000 hm
2, and now annual still with 2-3 ten thousand hm
2speed become silted up rise.Saline land control and exploitation are the problems that irrigated area agricultural development can not be ignored, and for promotion agricultural sustainable development, Ensuring Food Safety has important function.
The Method and Technology in domestic process saline land is summed up roughly as follows: (1) is physically improved; Level land, deep plough sun the earth which has been ploughed up, loosen the soil in time, raise landform, microcell is improved the soil.(2) water conservancy improvement.Fill with deploying cover, storage fresh water on saline-alkali land for leaching, washing salinity by irrigation, underground salt discharge.(3) chemical modifying; The chemical agents such as ardealite, superphosphate, fulvic acid are used to improve.(4) biological modification; Rice cultivation, plantation salt-tolerant plant Tian Qing etc., use microbial-bacterial fertilizer etc.At present, the soil conditioner of soil salinization chemical harnessing is more, as gypsum, calcium sulphate, superphosphate, trade waste ardealite, industrial waste acid, fertilizer, detritus acid, flyash, peat, fermentation acid-sludge etc., these all achieve certain effect to improvement saline land, relatively more conventional is fertilizer, gypsum, and wherein gypsum is with Ca
2+displacement Na
+and improved saline land by sour neutralization bases; But the restriction be subject to as complex manufacturing, poor processing effect and some other condition can not obtain large-area popularization.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the method that the two methylolurea+EDTA+ biological bacteria of a kind of ardealite+1'3-improves saline land.
The present invention is achieved by the following technical programs.
Two methylolurea+EDTA+ the biological bacteria of a kind of ardealite+1'3-provided by the invention improves the method in saline land, comprises the following steps:

Beneficial effect of the present invention is:
1), in this method, ardealite is aobvious acid, and it can neutralize with the saline land of aobvious alkalescence, effectively can reduce the pH value in saline land;
2) contained in ardealite calcium ion can with carbonate in saline land and bicarbonate radical generation chemical reaction, generate calcium carbonate and calcium bicarbonate, wherein calcium carbonate is water insoluble, calcium bicarbonate is slightly soluble in water, the character of calcium carbonate and calcium bicarbonate can impel Zinc fractions granular structure, and its granular structure can wrapping portion sodium ion, promotes desalinization of soil by flooding or leaching speed, reduce the bulk density of soil simultaneously, increase soil water permeability;
3) the two methylolurea of 1'3-is line-like structures, it has binding agent effect, the granular structure formed is reacted in ardealite and saline land, after the two methylolurea of interpolation 1'3-, the two methylolurea of 1'3-can promote the formation of granular structure, and the two methylolurea of 1'3-can fill up the vacancy position in the granular structure of calcium carbonate and calcium bicarbonate formation simultaneously, makes granular structure inside and outside portion relative insulation, reduce the sodium ion of mobility in soil, promote desalinization of soil by flooding or leaching speed;
4) the two methylolurea of 1'3-can slowly decompose at temperature and microbial action, and during decomposition, can form organic salt with the cation such as the sodium in soil, calcium, the solvability of its organic salt is low, the cation such as sodium, calcium of reduction soil free state;
5) the two methylolurea of 1'3-itself is slow-release fertilizer, and the product after its decomposition can provide nitrogen element for plant, can not cause the secondary pollution of soil;
6) when using the two methylolurea of 1'3-, add curing agent raw material, can impel the two methylolurea rapid curing of 1'3-, curing agent is used in combination with 1'3-pair of methylolurea, and granular structure can be impelled to be formed fast;
7) EDTA can react with the sodium in soil, calcium, iron ion complex compounds such as forming EDTA-Na, EDTA-Ca, EDTA-Fe, the solvability of EDTA-Na is lower than other sodium salts, and the complex compound that after EDTA-Ca, EDTA-Fe and iron, element is formed is slightly soluble in water, adds EDTA and can reduce salt content in soil;
8) stalk can increase the water penetration of soil, gas permeability and moisture retention, increases the content of organic matter of soil, and increase bacterial content in soil, bacterial population increase can reduce the part saliferous in saline land;
9) biological bacteria comprises bacillus subtilis, Azotica, salt tolerant rhizobium, salt tolerant Azospirillum brasilense, salt tolerant fixed nitrogen Klebsiella, Salt And Alkali Tolerance phosphate solubilizing bacteria, S. cervisiae, trichoderma reesei, nitrifying bacteria, alkaliphile, cellulose decomposition bacteria; Itself and stalk are used in combination, can grow fast, and absorb the part salinity in saline land in soil, reduce the salt content in saline land;
10) adopt biological bacteria and stalk to be pre-mixed fermentation, make biological bacteria amount reproduction, reduce the time in the saline land of biological bacteria process;
11) in the present invention, ardealite is first adopted to process saline land, reduce pH value, simultaneously by generating calcium carbonate, the granular structure such as calcium bicarbonate, and then add the materials such as the two methylolureas of 1'3-, the granular structure being is formed more fast, and fill up the position, space of granular structure, the inner relative insulation of the granular structure being, reduce the sodium ions content of the mobility in soil, the salt content in soil is reduced with this, add EDTA again, can with the sodium of granular structure outside, calcium, iron plasma reaction forms complex compound, reduce the salt content in the soil of granular structure outside, the last material adding stalk and biological bacteria mixed processing again, avoid relative strong basicity suddenly to the suppression of biological bacteria, biological bacteria is attached to stalk surface, fast processing is carried out to soil, absorb salinity, the object lowering soil salt is reached with this.
Adopt above-mentioned saline and alkali land improvement method, can quick improvement saline-alkali soil, suitable for crop grows, and this modifying agent operation strategies is wider, be applicable to different regions, salinization of soil soil melioration that different reason causes, rationally be manured into soil, can soil structure be improved, reduce soil alkalinity, improve soil salt discharge rate, increase soil fertility, promote the growth of crops, improve agricultural economy.
