Description

A kind of alkaline land improving medicament and alkaline land improving afforestation and soil preparation method

Technical field

The invention belongs to saline and alkali land improvement method technical field, specially a kind of alkaline land improving medicament and alkaline land improving Afforestation and soil preparation method.

Background technology

Salt-soda soil is the general name of various solonchak and alkaline earth and different degrees of salinization and alkali-affected soil.According to joint state religion section Text tissue and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.54 hundred million hectares, and China is about 99,000,000 hectares, Wherein modern about 37,000,000 hectares of saline-alkali soil, about 45,000,000 hectares of remaining saline-alkali soil, potential 17,000,000 hectares of saline-alkali soil.It is saline and alkaline Ground is a part for China's important land resources.

Salt affected soil is a kind of low productive soil based on alkaline cause harm, and it is impregnated by solubility salt with salinized soil .Alkali-affected soil is typically free of or containing only a small amount of soluble organic fraction, and containing more exchangeable sodium, alkaline reaction compared with By force, very heavy is poisoned to crop, also there is solid column illuvium sometimes, make soil physical property severe exacerbation.Due to soil The accumulation of interior a large amount of salinities, causes a series of deterioration of soil physical properties:Structure is viscous, and aeration is poor, and unit weight is high, in soil temperature Rise slow, aerobic microorganism activity is poor in soil, water release is slow, and infiltration coefficient is low, capillarity is strong, more causes topsoil The saliferous aggravation of earth.The saline and alkaline harm to plant shows 4 aspects:1)Cause the physiological drought of plant:Contain in solonchak Excessive solubility salt, can improve the osmotic pressure of the soil liquid, so as to cause the physiological drought of plant, make root system of plant and kind Can not be from the enough moisture of soil absorption during son germination, or even moisture is also resulted in from root cells extravasation, make plant wilt even dead Die.2)Injure plant tissue:Soil salt content is too high, especially in arid season, and salt, which gathers table soil, to be damaged to plumular axis, It injures ability with sodium carbonate, potassium carbonate, for maximum.Under high pH values, direct wound of the hydroxide ion to plant is also resulted in Evil.Gather excessive salt in some plants, and make plasm aggrieved, the synthesis of protein is seriously hampered, so as to cause The accumulation of nitrogenous intermediate metabolites, causes evil in cell.3)Plant normal nutrition is influenceed to absorb:Due to the competition of sodium ion, Reduce absorption of the plant to potassium, phosphorus and other nutrients, the transfer of phosphorus can be also suppressed, so as to influence the nutrition of plant Situation.4)The stomata of plant is influenceed to close:Under high concentration salts effect, the Starch formation in Stomacal guard cell is hindered Hinder, cause cell to close, therefore easily arid is withered for plant.People are long-standing for the research of alkaline land improving, I The saline alkali land area of state is wide, if salt-soda soil is used, and can significantly increase economic efficiency, phase is brought to country When considerable income, so we will greatly develop modified utilization for the characteristic in salt-soda soil.Put into practice in long-term production and living In, gradually form many effective technical measures.Salt-soda soil is improved, is on the one hand to exclude to have accumulated Salinity in soil, is on the other hand to prevent salinity from further running up in soil(That is the accumulation of salt in the surface soil).But the generation in salt-soda soil It is an extremely complex process with development, both by natural conditions, in terms of such as landforms, landform, soil, weather and hydrogeology The influence of factor, and by mankind's activity, such as Land-Use, agricultural cultivating mode, the influence of water engineering facility factor. Because the type of alkaline land soil is numerous and diverse, occurrence degree differs, and soil regime is different, wherein most active factor is soil reclaimed water Point, the motion of salinity, to improvement salt-soda soil add certain difficulty.

At present, alkaline land improving technical measures are mainly washed including site preparation method, Deep turning method of deep ploughing, method of hoing the fields, sand replacement method, draining Salt method, organic fertilizer method, chemical amendments and biological modification method etc..China is salinization of soil problem than more serious state Family, salinization of soil problem is always to influence a key factor of agricultural production.Reasonably to improve and utilize salinization of soil soil Earth, must just study its rule and feature, can just suit the remedy to the case, and take practicable ameliorative measure, and this part is considerable Reserved resources, be changed into preciousness land resource, be China agricultural sustainable development more contribute.
