Abstract
Provided is a greening method of severe saline-alkali soil, pertaining to the greening field of saline-alkali soil.The method is characterized by comprising following steps of 1, ploughing a saline soil area for planting seedlings under to great depth at about 50 to 80 cm; 2, selecting plant varieties of high tolerance to salt and alkali; 3, utilizing an excavator and manual labor to dig seedling plantation holes in advance, digging plantation holes for trees to the depth of 0.3 to 0.5 meters square and digging plantation holes for flowering shrubs at 0.1 to 0.3 meters square; 4, plantation after dug holes are differentiated under rainy season and winter; 5, making the plantation area of the slope to be terraced during plantation and performing seedling plantation after soil leveling of other plantation areas; 6, adding 30% to 35% of turfy soil in plantation soil and 20% to 30% of expanded chicken manure (or cow dung) during plantation; 7, adopting the plantation method of three-burying, two-treading and one-lifting to plant seedlings; 8, earthing up around holes at the shape of circular sills and covering sill surfaces with layers of thin films having holes in order to save water and increase moisture, and earthing up and compacting the films. The greening method of severe saline-alkali soil has following beneficial effects: survival rate of landscaping and plantation is effectively increased; survival rate of salt-tolerant plants on saline soil of 0.5 to 1.2 % in saltness is up to more than 70%; and the method is easy in operation, low in cost and easy in promotion.
Description
Technical field
The invention belongs to saline land greening field, particularly a kind of method of afforesting heavy salinizedly.
Background technology
Saline land refers to that those salt contents are high, and pH is greater than 9, is difficult to the soil of growing plant especially crops.According to contained salinity and alkali part number, also can be further divided into slight (0.1% ~ 0.25%), moderate (0.25% ~ 0.5%) and heavy salinized (0.5% ~ 0.6%).Formation many-sided coefficient result often in saline land.If soil itself, containing more mineral matter, just easily becomes the source of saline and alkaline gathering after these mineral matter weathering.Groundwater effect is also very large, always with salinity in underground water.When groundwater level is higher, this area is comparatively arid, underground water can evaporate because of the effect of capillarity, and salinity just remains among soil, supplements if can not get enough moisture, and the soil of this area just can become saline land.If soil is loamy texture composition, it is faster, highly higher that underground water rises.Sandy soil and clay are then slower.In the area that summer rainfall is more, salinity can be poured deep soil or flow into rainwash by a large amount of precipitation.At this moment there will be seasonal desalination.If soil is positioned at the relatively high low laying areas of subterranean water level, the salt ground water of surrounding also can be caused to assemble and salinization of soil to this place.Manpower impact can cause the salinization of soil equally, and such as in the agrarian area adopting flood irrigation, the rising of subterranean water level can cause salinization of soil.This process is called secondary salinization.The minimizing of surface vegetation can make water evaporation rate rise, and also easily produces saline Land, and therefore overcut, overgraze are also the inducements causing secondary salinization.Salinity in salt affected soil is very serious to the injury of the root system of plant, and the root system of plant is subject to after salt poisons, the bad and early ageing of root system development.In alkaline land soil, salinity is many, soil table normal adularescent salt alkali precipitation, ventilation, permeable bad, root system of plant often has poisoning, rotten, the phenomena of mortality.
Saline-alkali soil area due to salt content higher, be mostly barren land, in the urgent need to improving greening environment looks.Utilize saline land to plant trees, not only can expand forest coverage, improve regional ecotope, can also saline-alkali soil be improved, bring more land under cultivation, eliminate salt damage, promote agricultural production.But in varieties in saline-alkali areas because salt accumulation in soil is too much, tree root absorbs moisture, nutrient is very difficult, destroy normal water metabolism in trees body, cause physiological phenomenon arid, present wilting phenomenon or growth stopping, even dead, bring sizable difficulty to saline land Garden Greening Work.At present, planting greening is being carried out mainly through physics, river construction, chemistry and the measure such as biological improvement saline land in saline land, and the time cycle is long, and cost is high.How solving greening on saline land is when the difficult problem of forward swing in face of numerous Gardener author, is also ecology of alkali saline land gardens " bottlenecks ".
Summary of the invention
The object of the invention is the deficiency for existing heavy salinized ground greening technique, a kind of method of afforesting is provided heavy salinizedly.
Object of the present invention realizes by following technical scheme: a kind of method of afforesting, comprises the following steps heavy salinizedly: 1, need the saline and alkaline region original position of planting nursery stock to plough deeply 50-80 centimetre; 2, the plant variety of high Salt And Alkali Tolerance is selected; 3, according to salt tolerant nursery stock size, usage mining machine and the method manually combined excavate seedling growth cave in advance, and it is square that general arbor digs kind of plant hole 0.3 ~ 0.5 meter, and flowering shrub kind plant hole 0.1 ~ 0.3 meter is square; 4, the cave after excavating will be planted through the differentiation in rainy season and winter again; 5, planting area during plantation on hillside will make terrace type, carries out seedling growth again after other planting area leveling earth; 6,30% ~ 35% turfy soil to be added in planting soil, 20 ~ 30% expanded chicken manures (or cow dung) during plantation; 7, " three bury two step on one carry " method of planting is adopted to plant seedlings; 8, in the ridging of cave surrounding, form circular earth steps, be covered with one deck film with holes to retain and conserve soil moisture at earth steps table, compacting that film is earthed up.Adopt this invention to effectively raise the survival rate of saline land afforestation plantation, on salt content 0.5% ~ 1.2% solonchak, salt-tolerant plant survival rate is to more than 70%.The present invention is simple to operate, with low cost, is easy to promote.
Beneficial effect of the present invention:
1, the present invention is saline land original position planting greening method, simple to operate, with low cost, is easy to promote.
2, the present invention ploughs deeply 50-80 centimetre by saline and alkaline region original position, usage mining machine and the method manually combined excavate seedling growth cave in advance, cave after excavation will be planted through the differentiation in rainy season and winter again, plays chesson, strengthens water penetration, improves the effect of drenching salt salt discharge.
3, the present invention is by applying turfy soil, expanded chicken manure (or cow dung), can soil physical property be improved, increase soil aggregate, salt affected soil is loosened, reduce salt affected soil to harden, be conducive to water conservation, fertilizer conservation, ventilation and promotion plant root system development.
4, the present invention is by the ridging of cave surrounding, forms circular earth steps, is covered with one deck film with holes to retain and conserve soil moisture at earth steps table, film to be earthed up compacting, play draining timely, improve salt discharge efficiency, suppress plant root evaporation from topsoil simultaneously, form the ecotope of suitable for plant survival.
