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 salt-soda soil, not only there is the biggest harm in these salt-soda soils to agricultural production, in today of city Large scale construction, urban afforestation are had equally to negative effect clearly.
At present the modification method in salt-soda soil is had following several:
1, plough deeply: soil deep ploughing is turned over and i.e. salinity in topsoil is turned upside down to topsoil below, and less for lower floor's saliferous soil is translated into surface.Turn over arable layer of loosening, cut off soil capillary, weaken soil water evaporation, efficiently control the soil accumulation of salt in the surface soil；
2, applying organic manure, rational use of chemical fertilizer: the greening such as square and road usually from adapts to road or building height and soil moved in improve the original allocated and transported again by needs, and allocate and transport the deep layer groove soil that the soil moved in improve the original come is building excavation mostly, and our raw-soil of often saying, it is extremely low that this soil shows as the content of organic matter, soil soft degree differences etc., need the maturing process through soil.After applying organic manure, organic matter produces a large amount of organic acid in catabolic process, and on the other hand aspect can be accelerated nutrient decompose with sweetening of the soil alkalescence, promotes to imitate late Nutrient Transformation, raising P availability；Chemical fertilizer can be given in soil increases N P and K, promotes plant growth, improves the Salt-endurance of crop.But the consumption of chemical fertilizer every time can not be too much, to avoid adding the Secondary Saline of heavy soil, should be in conjunction with pouring water after executing chemical fertilizer, to reduce soil liquid concentration；
3, it is used in combination soil conditioner finished product, uses advanced technology to promote soil property optimization；
4, the method using the desalinization of soil by flooding or leaching: the drainage trenching when improveing square soil, pours water in a large number to ground, makes soil salt dissolve, and when water is oozed out by gutter, is extracted out by aqueous alkali, in order to alleviate surface soil alkalinity；
5, level land while square replacing lawn, rake the soil level in good time: level land and can make to ooze under uniform moisture, improve rainfall drench salt and irrigate the effect of the desalinization of soil by flooding or leaching, prevent soil plaque-like salination, the table soil that can loosen of raking the soil level, block soil capillary water and carry salinity to earth's surface, play the effect preventing the accumulation of salt in the surface soil；
6, the area that soil alkaline ground is serious, when using subsoil water to irrigate.
In said method, current people are more likely to use soil conditioner to carry out soil improvement, this method instant effect, and novel soil conditioner constantly occurred in recent years, while application, will pay attention to the impact on environment.Along with people's economic consciousness and the enhancing of environmental consciousness, the environmental type soil conditioner researching and developing efficient low consumption becomes the emphasis of research.
The soil conditioner used when improveing salt affected soil at present environmental protection generally not, therefore, it is necessary to develop the salt affected soil modification method of a kind of environmental protection.
Summary of the invention
Goal of the invention: the invention aims to solve the deficiencies in the prior art, it is provided that a kind of North China salt affected soil modification method.
Technical scheme: in order to realize object above, the present invention adopts the following technical scheme that
A kind of North China salt affected soil modification method, uses soil conditioner to alkaline land soil, and amount of application is 300-400kg/hm2, the soil conditioner used includes each component of following weight portion:
Humic acid and the mixture of ardealite: 45-50 part；
Natural zeolite: 8-10 part；
Powder of straw: 10-15 part；
Wormcast: 15-20 part；
Spartina alterniflora and the mixture of sheep stool: 15-25 part
Kieselguhr: 5-8 part.
Preferably, described humic acid and the mixture wherein humic acid of ardealite are 1:1 with the mass ratio of ardealite.
Preferably, the mass ratio of the mixture of described Spartina alterniflora and sheep stool wherein Spartina alterniflora and sheep stool is 2:1.
Preferably, one or both during described powder of straw is Semen Maydis and wheat stalk powder.
It is further preferred that described powder of straw is the powder becoming particle diameter to be 0.8-1.0mm crushed stalk, then sterilizing 30min at 120-122 DEG C, under the conditions of 60 DEG C, then dry 24 h prepare.
Preferably, the mixture of described Spartina alterniflora and sheep stool obtains especially by following method: Spartina alterniflora removes root and the higher leaf portion of salinity, makes particle diameter at 1-2cm remainder chopping
Between, using sheep stool as nitrogen source additive, adding Spartina alterniflora and sheep stool by dry biomass than 2: 1, regulation is to C: N ratio 30: 1, and the regulation moisture content that adds water is to 50-55%.
Beneficial effect: North China's salt affected soil modification method that the present invention provides compared with prior art, has the advantage that
1, the soil conditioner used in the soil improvement method of the present invention, uses natural mineral matter and natural straw and natural vegeto-animal wormcast, sheep stool, environmental protection, is easy to get, with low cost, is the soil improvement method of a kind of environment protecting and power-saving；
2, use ardealite and can improve soda type saline-alkali soil humus content, polyphenol oxidase activity, cellulase activity, catalase activity, soil salt content can be significantly reduced, improve crop dry-matter accumulation amount and yield, but Gypsum Fibrosum effect on reduction soil pH value is the most notable, therefore, during gypsuming improvement saline-alkali soil there is time alkalization in soil to be prevented, and humic acid and Gypsum Fibrosum join execute process after soil salt content and pH value reduce at most, be also prevented from soil simultaneously and occur time to alkalize；
3, the mixture of Spartina alterniflora and sheep stool can make Soil structure be improved, and soil nutrient improves, and soil microbial activities strengthens；
4, the process applying wormcast can increase Cation Exchange Capacity in Soils, and increases along with the increase of wormcast content；The basicity of soil can be significantly reduced, and reduce along with the increase of content；Carbon in soil acid group and the content of heavy carbonic root can be significantly reduced, reduce soil total alkalinity, and reduce facing to the increase of wormcast content；
5, the saline-alkali soil after using the inventive method to process, its pH value can reduce by more than 0.85, and soil organic matter content improves 60-70%, and crops can increase income 8.5-17.2%.
