Description

High salt soil conditioner

Technical field

The present invention relates to soil redeposition field, especially a kind of high salt soil conditioner of activity being exclusively used in high saline land soil improvement.

Background technology

Saltings is a kind of salt aggregation, refer to that salinity contained inside soil has influence on the normal growth of crop, according to UNESCO and food and agricultural organization's incomplete statistics, the area in saltings, the whole world is 9.5438 hundred million hectares, and wherein China is 9,913 ten thousand hectares.The formation of China's alkaline earth and alkali-affected soil, major part is accumulative relevant with Carbonates In Soil, and thus basicity is general higher, and serious salt affected soil regional plant almost can not be survived.

Various saline-alkali soil is all formed under certain natural condition, and its essence formed mainly various processable salt does redistributing of horizontal direction and vertical direction on ground, thus the upper soll layer that salinity is collecting salt area is built up.The basic reason that saline-alkali soil is formed is that water regime is bad, so at the improvement initial stage, emphasis should be placed on and improve above water regime of soil.A general point a few step is carried out, first salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content; Plant the plant of Salt And Alkali Tolerance again, fertilizing soil; Last long-term cropping.Concrete ameliorative measure is: draining, and irrigate the desalinization of soil by flooding or leaching, warp improvement, rice cultivation, improvement of fostering and apply fertilizer, levels land and chemical modifying.

The modification method in saltings mainly contains following several:

One, the desalinization of soil by flooding or leaching

The desalinization of soil by flooding or leaching is poured into water in saltings exactly, and soil salt is dissolved, by under being oozed and be discharged in deep soil or drip washing is gone out saline and alkaline for the solubility in topsoil, infiltration waterways, side is got rid of.

Two, level land

Level land under can making uniform moisture and ooze, improve the effect that rainfall is drenched salt and irrigated the desalinization of soil by flooding or leaching, prevent the salinification of soil plaque-like.Deep ploughing is ploughed deeply.The distribution situation of salinity in soil is that surface layer is many, and lower floor is few, through ploughing, salinity in topsoil can be turned upside down to topsoil following, soil less for lower floor's saliferous is translated into surface.To turn over arable layer of loosening, cut off soil capillary, weaken soil water evaporation, effectively control the soil accumulation of salt in the surface soil.Preferably spring and autumn time turned in saltings.Spring, autumn are the accumulation of salt in the surface soil heavier seasons.Plough autumn and be particularly advantageous in killing disease worm's ovum, weed a garden, buried stubble, strengthen the release of organic matter decomposition and slow effect nutrient, so be worth advocating.

Three, rake the soil level in good time

Raking the soil level to loosen shows soil, blocks soil capillary water and carries salinity to earth's surface, play the effect preventing the accumulation of salt in the surface soil.Rake the soil level and want in good time, shallow spring ploughing, rob volt cultivated, early autumn ploughing, plough dry not ploughing and wet.

Four, applying organic manure, rational use of chemical fertilizer

Generally there are low temperature, soil is thin, structure is poor feature in saltings.Fertilizer forms soil ulmin through microbial decomposition, conversion, can improve the surge capability of soil, and can form sodium humate with sodium carbonate effect, reduces surface soil alkalinity.Sodium humate can also stimulate plant growth, strengthens saline-alkaline tolerance.Soil ulmin can promote that crumb structure is formed, thus cell size is increased, and water-permeable strengthens, and is conducive to salt leaching, suppresses the accumulation of salt in the surface soil.Organic in decomposition course, produce a large amount of organic acid, on the one hand can sweetening of the soil alkalescence, can decompose of nutrient be accelerated on the other hand, promote to imitate Nutrient Transformation late, improve P availability.Therefore, applying organic manure material is improvement saltings, the important measures of increasing soil fertility.In addition, chemical fertilizer is also subject to people to the saline and alkaline effect of improvement and payes attention to, and chemical fertilizer increases N P and K in soil, promotes plant growth, improves the Salt-endurance of crop.Use chemical fertilizer and can change soil salt composition, suppress salt to the detrimentally affect of plant.Inorganic fertilizer can increase crop yield, has more stalk, expands organic fertilizer resource, with inorganic short organic.Certainly, to avoid using alkaline fertilizer when chemical fertilizer is used in saltings, as ammoniacal liquor, bicarbonate of ammonia, lime nitrogen, fused(calcium magnesium)phosphate etc., and should with neutral and acidic fertilizier as well.Compound potassium sulfate fertilizer is subacidity fertilizer, is adapted at saltings is used, and has the good action in improvement saltings.

Although the improvement in saltings has had the method for comparison system now, but cost is higher mostly, cycle is longer, consider that some seeds can resistance to barrenr saltings, such as arrow-leaved oleaster, can stand vitriol is main solonchak, also has the effect reducing soil salt, through good tending management, still can grow into forest on the ground at high solonchak, but the arrow-leaved oleaster of Seedling Stage not easily survives.

Summary of the invention

The present invention in order to solve the problem that the salt tolerant such as the arrow-leaved oleaster of Seedling Stage tree kind not easily survives in high salt soil, provides a kind of salt tolerant seeds easily to survive just, be easy to the high salt soil conditioner that grows into forest.
