Abstract
The invention provides an improvement method of saline alkali soil in North China areas. The method lies in that a soil improvement agent with an application rate of 300 to 400 kg/ hm<2> is applied in saline alkali soil, and the applied soil improvement agent comprises the following components in parts by weight: 45 to 50 parts of a mixture of humic acid and phospho gypsum, 8 to 10 parts of natural zeolite, 10 to 15 parts of straw powder, 15 to 20 parts of wormcast, 15 to 25 parts of a mixture of spartina alterniflora and sheep manure and 5 to 8 parts of diatomaceous earth. According to the improvement method of the saline alkali soil in North China areas, the PH value of the saline alkali soil treated through adopting the method is reduced by 0.85 above, the organic content of the soil is increased by 60% to 70%, and the crop yield is increased by 8.5% to 17.2%.
Description
Technical field
The present invention relates to a kind of North China salt affected soil modification method.
Background technology
Due to geology and climatic reason, northern China, especially North China, there is large-area saltings, not only there is very large harm in these saltingss to agriculture production, the today of building at Urban Large scale, have equally negative effect clearly for urban afforestation.
At present the modification method in saltings is had following several:
1, plough deeply: soil deep ploughing turns over salinity in topsoil to be turned upside down to topsoil following, and soil less lower floor's saliferous is translated into surface.The arable layer of loosening of turning over, cuts off soil capillary, weakens soil water evaporation, effectively controls the soil accumulation of salt in the surface soil;
2, applying organic manure, rational use of chemical fertilizer: the greenings such as square and road are are usually allocated and transported soil moved in to improve the original again for adapting to road or building height needs, and the soil moved in to improve the original that allocation and transportation come is the deep layer groove soil of building excavation mostly, and our immature soil of often saying, it is extremely low that this soil shows as organic content, the soft degree of soil is poor etc., need to be through the maturing process of soil.After applying organic manure, organic in decomposition course, produce a large amount of organic acids, aspect can sweetening of the soil alkalescence, can accelerate on the other hand decompose of nutrient, promotes effect Nutrient Transformation late, improves the validity of phosphorus; Chemical fertilizer can be given in soil increases nitrogen phosphorus potassium, promotes plant growth, has improved the Salt-endurance of crop.But the consumption of chemical fertilizer at every turn can not be too much, to avoid adding the Secondary Saline of heavy soil, executing should be in conjunction with pouring water, to reduce soil solution concentration after chemical fertilizer;
3, be combined with soil improvement agent finished product, uses advanced technology promotes soil property optimization;
4, adopt the method for the desalinization of soil by flooding or leaching: drainage trenching in the time of the soil of improvement square, poured water in a large number in ground, soil salt is dissolved, in the time that water is oozed out by waterways, buck is extracted out, in order to alleviate surface soil alkalinity;
5, level land, rake the soil level in good time when square replacing lawn: level land and can make moisture ooze under evenly, improve the effect that rainfall is drenched salt and irrigated the desalinization of soil by flooding or leaching, prevent the salinification of soil spot shape, raking the soil level to loosen shows soil, block soil capillary water and carry salinity to earth's surface, play the effect that prevents the accumulation of salt in the surface soil;
6, serious area, soil alkaline ground, while being used underground water to irrigate.
In aforesaid method, people are more prone to adopt soil improvement agent to carry out soil improvement at present, this method instant effect, and novel soil conditioner constantly occurred in recent years, in application, pay attention to the impact on environment.Along with the enhancing of people's economic consciousness and environmental consciousness, the environmental type soil improvement agent of researching and developing efficient low consumption becomes the emphasis of research.
The soil improvement agent using when at present salt affected soil improvement is environmental protection not conventionally, therefore, is necessary to develop a kind of salt affected soil modification method of environmental protection.
Summary of the invention
Goal of the invention: the object of the invention is in order to solve the deficiencies in the prior art, a kind of North China salt affected soil modification method is provided.
Technical scheme: in order to realize above object, the present invention adopts following technical scheme:
A kind of North China salt affected soil modification method, uses soil improvement agent to alkaline land soil, and amount of application is 300-400kg/hm
