Description
Technical field
The present invention relates to betterment of land technical fields, and in particular to a kind of Novel planting method for improveing salt-soda soil.
Background technique
Saline alkali land area is wide in world wide, according to UNESCO and food and agricultural organization's incomplete statistics, entirely
The area in world salt-soda soil is 9.5 hundred million hectares, and wherein China is 0.99 ten thousand hectares, close to 100,000,000 hectares, that is, 1,500,000,000 mu.Its
In, 2.8 hundred million mu of salt-soda soils are to be badly in need of transformation, in this 2.8 hundred million mu of salinization lands, have 1.4 hundred million mu it is red in 1,800,000,000 mu of arable lands
It is 1.4 hundred million mu remaining within line, it is the Unutilized Energy that Ministry of Land and Resources defines.
With the increase of urban size, cultivated area is constantly reduced, while the size of population is continuously increased, and the mankind are also facing
The severe challenge of grain.
Since natural conditions are severe, salinity content is high in salt-soda soil, and it is less to can adapt to the crop grown in salt-soda soil.Rice
It is the staple food crop in China, there is nearly 2/3 population in the whole nation using rice as staple food.Rice cropping area accounts for foodstuff planting area
1/3, but yield accounts for about the 40% of total output of grain.
Therefore Rice Production is extremely important in guarantee China's grain security supply respect.Existing research card
Bright, salt alkaline tolerance rice has certain salt tolerant alkali ability, can be effectively reduced soil salinity and alkalinity, reaches the effect in improvement salt-soda soil
Fruit.Salt-soda soil kind rice simultaneously, and sufficient grain yield can be provided, ensure the grain-production safety in China.
The basic reason that saline-alkali soil is formed is that water regime is bad, so emphasis should be placed on improvement soil at improvement initial stage
Above the water regime of earth.It is generally carried out in several steps, first salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content；Saline-alkali tolerant is planted again
Plant, fertilizing soil；Last long-term cropping.Specific ameliorative measure is: the desalinization of soil by flooding or leaching is irrigated in draining, warps improvement, rice cultivation,
Fertilizing improvement, levels land and chemical modifying.
Saline-alkali soil is the general name of solonchak and alkaline earth.Solonchak refers mainly to chloride or the higher salinization soil of sulfate,
Soil is in alkalinity, but pH value is not necessarily very high.Alkaline earth refers to carbonate containing or the phosphatic soil of weight, and pH value is higher, and soil is in
The content of organic matter of alkalinity, saline-alkali soil is few, and soil fertility is low, and physicochemical character is poor, more to the harmful anions and canons of crop, crop
It is not easy to promote seedling.The fertilization principle of saline-alkali soil is to control the use of low concentration chemical fertilizer based on organic fertilizer material and efficient compound fertilizer.
Organic fertilizer contains a large amount of organic matter, works as a buffer to harmful anions and canons in soil, is conducive to root of hair, promotees seedling.It is highly concentrated
It is few to spend compound fertilizer's invalid components, residual is few, but the dosage of chemical fertilizer every time can not be excessive, to avoid the Secondary salinization for aggravating soil
Change, applying should be in conjunction with pouring water, to reduce soil liquid concentration after chemical fertilizer.
In the prior art, the modification method in salt-soda soil is as follows:
1, the desalinization of soil by flooding or leaching.The desalinization of soil by flooding or leaching be exactly water is poured into salt-soda soil, dissolve soil salt, by it is lower seep in topsoil can
Dissolubility is saline and alkaline to be discharged in deep soil or elutes away, and side is penetrated into gutter and excluded.

Soil plaque-like salination.Deep ploughing is ploughed deeply.The distribution situation of salinity in the soil is that surface layer is more, and lower layer is few, can be by ploughing
Salinity is turned upside down to that topsoil is following in topsoil, and the less soil of lower layer's saliferous is translated into surface.The loose arable layer of energy is turned over, is cut
Disconnected soil capillary, weakens soil water evaporation, efficiently controls the soil accumulation of salt in the surface soil.The time that salt-soda soil is turned over be preferably spring and
Autumn.Spring, autumn are the accumulation of salt in the surface soil heavier seasons.Autumn, which ploughs, to be particularly advantageous to kill disease pest ovum, removes weeds, buried root stubble adds
Strong organic matter decomposition and the late release of effect nutrient, so being worth advocating.
3, it rakes the soil level in due course.Rake the soil level can loose surface soil, truncation soil capillary water to earth's surface convey salinity, playing prevents the accumulation of salt in the surface soil
Effect.Raking the soil level will shallowly plough in the spring in due course, rob volt and plough, early autumn ploughing, plough it is dry do not plough it is wet.
4, applying organic manure, rational use of chemical fertilizer.Salt-soda soil generally has the characteristics that low temperature, soil is thin, structure is poor.Organic fertilizer warp
Microorganism decomposition, conversion form humus, can improve the buffer capacity of soil, and can act on forming sodium humate with sodium carbonate,
Reduce surface soil alkalinity.Sodium humate can also stimulate plant growth, enhance saline-alkaline tolerance.Humus can promote crumb structure shape
At so that cell size be made to increase, water penetration enhancing is conducive to salt leaching, inhibits the accumulation of salt in the surface soil.Organic matter generates greatly in decomposable process
Organic acid is measured, surface soil alkalinity on the one hand can be neutralized, on the other hand nutrient can be accelerated to decompose, promotes effect Nutrient Transformation late, improves
P availability.Therefore, applying organic manure material is improvement salt-soda soil, the important measures increase soil fertility.In addition, chemical fertilizer is to changing
Good saline and alkaline effect is also paid attention to by people, and chemical fertilizer promotes plant growth, improve the resistance to of crop to N P and K is increased in soil
Salt power.Application chemical fertilizer can change soil salt composition, inhibit adverse effect of the salt to plant.Inorganic fertilizer can increase and make produce
Amount has more stalk, expands organic fertilizer resource, organic with inorganic rush.Certainly, it to avoid applying alkaline fertilizer when salt-soda soil application chemical fertilizer
Material, such as ammonium hydroxide, ammonium hydrogen carbonate, lime nitrogen, calcium magnesium phosphate, and should be preferably neutral and acidic fertilizier.Compound potassium sulfate fertilizer is
Subacidity fertilizer is suitble to apply on salt-soda soil, and has the good action in improvement salt-soda soil.
5, non-chemical means prevention and treatment, can effectively improve soil with salt-soda soil special-purpose soil conditioner " solodization ",
The first, metal ion exchanged in soil can be promoted to release, reduce salt content；The second, a kind of plant source extraction acid is included
Property substance, can effectively neutralize soil neutral and alkali ingredient, and do not generate any injury to plant and soil itself, meet following green
Color agricultural development direction；Third, this plant source acidic materials itself have the viroses of plant prevents and treats effect well,
The generation of plant seedling stage disease can be effectively prevented.
And clover is as a kind of green manure crop, and its own does not like water, can be with effectively save water resource, and there is saline-alkali tolerant energy
Power, at the same clover because containing rhizobium can effective fixed nitrogen, certain nitrogenous fertilizer is provided for soil, it is fertile to improve saline and alkaline middle soil
Power lays fertility basis for Rice Cropping.The clover of production can be used as green manure, turn in soil, improve soil disease knot
