Description
Technical field
The present invention relates to saltings processing technology field, particularly relate to a kind of alkaline land modifying agent and the using method that contain phosphogypsum and sustained-release adhesive.
Background technology
Saltings 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 saltings.
Saltings is important land resources, and it is a kind of soil type 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 total area reaches more than 500,000,000 mus, and account for that the whole nation can utilize land area nearly 5%.The wherein total area in Coastal beach saltings about 2,350,000 hm
2, and now annual still with 2-3 ten thousand hm
2speed become silted up rise.Saltings 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 vital role.
The Method and Technology in domestic process saltings 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; Phosphogypsum, calcium superphosphate, humic acid etc. is used to improve.(4) biological modification; Rice cultivation, plantation salt-tolerant plant Tian Qing etc., use microbial-bacterial fertilizer etc.At present, the soil improvement agent of soil salinization chemical harnessing is more, as gypsum, calcium sulfate, calcium superphosphate, trade waste phosphogypsum, industrial waste acid, fertilizer, detritus acid, flyash, peat, fermentation acid-sludge etc., these all achieve certain effect to improvement saltings, relatively more conventional is fertilizer, gypsum, and wherein gypsum is with Ca
2+displacement Na
+and improved saltings 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 a kind of alkaline land modifying agent and the using method that contain phosphogypsum and sustained-release adhesive.
The present invention is achieved by the following technical programs.
A kind of alkaline land modifying agent containing phosphogypsum and sustained-release adhesive provided by the invention, this alkaline land modifying agent comprises the raw material of weight part: phosphogypsum 100 ~ 600 parts, humic acid 5 ~ 30 parts, sustained-release adhesive 5 ~ 25 parts, 0.1 ~ 5 part, zinc sulfate, polyoxyethylene glycol 0.1 ~ 5 part;
The structural formula of above-mentioned sustained-release adhesive is: H-[OCH2NHCONHCH2] n-OH, wherein 2≤n≤10;
Above-mentioned all raw materials are deposited all separately.
Further, described alkaline land modifying agent is made up of the raw material of following weight part: phosphogypsum 350 parts, humic acid 15 parts, sustained-release adhesive 15 parts, 1 part, zinc sulfate, polyoxyethylene glycol 1 part.
Present invention also offers a kind of using method containing the alkaline land modifying agent of phosphogypsum and sustained-release adhesive, according to the amount of application of the salt content determination modifying agent in saltings simultaneously; Concrete steps are:
(1) first by after phosphogypsum and humic acid mixing, saline and alkaline the earth's surface is evenly sprinkling upon, and the 20cm that deep ploughs, phosphogypsum and humic acid are mixed with soil layer, keeps 5 ~ 20 days;
(2) then sustained-release adhesive, zinc sulfate, polyoxyethylene glycol are evenly sprinkling upon surface, saltings respectively, and the 20cm that deep ploughs, sustained-release adhesive, zinc sulfate, polyoxyethylene glycol are mixed with soil layer, keeps 20 ~ 30 days.
Further, the amount of application of the described salt content determination modifying agent according to saltings is specially: the alkaline land modifying agent using 200 ~ 600kg/ mu at slight alkaline land, uses the alkaline land modifying agent of 600 ~ 1000kg/ mu in moderate saline-alkali soil; At heavy salinized the alkaline land modifying agent using 1000 ~ 1500kg/ mu.
Further, described step (2), after sustained-release adhesive, zinc sulfate, polyoxyethylene glycol mix with soil layer, to soil layer spray water, makes the soil layer that saltings 20cm is dark moistening.
Beneficial effect of the present invention is:
1) phosphogypsum is aobvious acid, and it can neutralize with the saltings of aobvious alkalescence, coordinates the use of humic acid, effectively can reduce the pH value in saltings;
2) contained in phosphogypsum calcium ion can with carbonate in saltings and bicarbonate radical generation chemical reaction, generate calcium carbonate and Calcium hydrogen carbonate, wherein calcium carbonate is water insoluble, Calcium hydrogen carbonate is slightly soluble in water, the character of calcium carbonate and Calcium hydrogen carbonate can impel Zinc fractions spherulitic texture, and its spherulitic texture can wrapping portion sodium ion, promotes desalinization of soil by flooding or leaching speed, reduce the soil weight simultaneously, increase soil water permeability;
3) sustained-release adhesive is line-like structures, it has binding agent effect, the spherulitic texture formed is reacted in phosphogypsum and saltings, after interpolation sustained-release adhesive, sustained-release adhesive can promote the formation of spherulitic texture, and sustained-release adhesive can fill up the vacancy position in the spherulitic texture of calcium carbonate and Calcium hydrogen carbonate formation simultaneously, makes spherulitic texture inside and outside portion relative insulation, reduce the sodium ion of mobility in soil, promote desalinization of soil by flooding or leaching speed;
4) sustained-release adhesive can slowly decompose at temperature and microbial process, and during decomposition, can form organic salt with the positively charged ion such as the sodium in soil, calcium, the solubleness of its organic salt is low, reduces the positively charged ion such as sodium, calcium of soil free state;
5) sustained-release adhesive 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 sustained-release adhesive, adding zinc sulfate, polyoxyethylene glycol raw material, sustained-release adhesive fast setting can be impelled, spherulitic texture can be impelled to be formed fast.
The present invention adopts the alkaline land modifying agent of above-mentioned formula, coordinates its using method, and it can quick improvement saline-alkali soil, suitable for crop grows, and the salting of soil soil improvement that this modifying agent operation strategies is comparatively wide, is applicable to different areas, different reason causes, is rationally manured into soil, Soil structure can be improved, reduce soil alkalinity, improve soil salt discharge rate, increase soil fertility, promote the growth of farm crop, improve rural economy.
