Description
Technical field:
The present invention relates to a kind of desertification and administer ground and improvement method thereof, belong to reconstruction and the recovery field of the ground ecosystem that desertifies.
Background technology
Desertifying, large stretch of soil aggravates the degeneration of ecotope, the fast reducing of species diversity in just at full speed engulfing, and produces and brings great threat simultaneously to farming and animal husbandry.To the administration way on the ground that desertifies mainly contain fence fencing, braiding sand-protecting barrier, the husky raw seeds and broadcast sowing grass seeds planted.These methods are not single carrying out, and often integrate and carry out.First with fence, improvement region is sealed, then weave therein sand-protecting barrier, the seeds and broadcast sowing grass seeds planted.Utilize vegetation progressively to improve desertification Di habitat, thereby reach the effect of improvement.
But the extreme climatic environment that desertifies can not only depend on the improvement to the habitat, ground of desertifying of self vegetation, how fast, practicablely to desertifying, administer, also need further to understand the formation on the ground that desertifies.The formation on ground of desertifying has been divided two classes from the source of sand, and a class is to play on the spot sand, with the form of blowout, exists.Another kind is to rely on carrying of wind-force, and final settlement is on other meadows or forest land and form sand ground, and overburden depth can reach 7m～10m.No matter be to play on the spot sand or the sand ground of sand sedimentation formation, its basic characteristics are all that vegetation cover degree is low, soil is extremely barren and water retention capacity is low.Wind erosion sand pit is after having experienced the wind erosion of annual winter-spring season, and vegetation root system is exposed to the sun in a large number in air, adds the irradiation of red-hot sunlight, withered very soon.Be brought to other local sands because of self gravitation effect, the grains of sand are sedimentation earthward, and glutinous grain wherein floats to farther place.
Basic characteristics based on sand ground, the more current method of administering the ground that desertifies of combination, what the discovery desertification ground of being not difficult lacked most is exactly the ability of soil water-retaining and fertilizer conservation.Between these two characteristics, be also related, that is exactly that water retention property lowly means that fertilizer-preserving ability is low simultaneously.Water retention property is poor, and nutriment easily runs off, and makes originally with regard to very barren desertification ground, to lack all the more nutrient.The shortage of liquid manure is disadvantageous to the growth of vegetation.Research is found, vegetation as easy as rolling off a log susceptible insect pest under the condition that lacks moisture or nutrient is even directly withered.
In view of desertifying, ground water retention property is poor, nutrient is easy to the feature running off, and some scholars are at sand ground lower floor layer overlay film, for water conservation and fertilizer conservation.Although can keep portion of water and nutrient here in certain hour and spatial dimension, this does not fundamentally change the characteristic of Sandy Soil.
The improvement on ground of desertifying is extremely urgent, only relies on fence fencing, weaves sand-protecting barrier, the seeds of planting, to broadcast sowing grass seeds and spreading etc. be far away inadequate.From current desertification the present situation of being growing on and on can find out, the improvement on the ground that desertifies is very urgent.
Summary of the invention
A kind of desertification that the object of the invention is to develop for the deficiencies in the prior art administered ground and the improvement method on the ground that desertifies, be characterized on the basis of merits and demerits of summing up existing improvement technology, poor according to Sandy Soil water conservation and fertilizer-preserving ability, the soil that nutrient is rich in utilization is filled in desertification ground, for creating a good liquid manure environment in the habitat of desertifying severe, promote the growth of vegetation, make the dry branches and fallen leaves that vegetation produces retain, for the coming year vegetation growth better habitat is provided.
Regulation effect of the present invention is realized by following technical measures:
Desertify and administer ground by a plurality of patches, a plurality of gallery and utilize gallery that these patches are coupled together, and then form larger scope-matrix.
Each patch of described a plurality of patches is 400m
2～10000m
2, patch orientation and the ground propagation direction that desertifies, cardinal wind are vertical, reach the effect of checking winds and fixing drifting sand.
On each patch of described a plurality of patches, offer several ditches, ditch depth is 30cm～40cm, and furrow width is 20cm～40cm, the long 2m～10m of ditch, and the spacing of ditch and ditch is 4m～8m, ditch inner stuffing is soil and cow dung barnyard manure mixture.
The ditch shape of ditching on described patch is any in square, trapezoidal, U-shaped or V-arrangement.
In each of described a plurality of gallerys, offer several ditches, ditch depth is 30cm～40cm, and furrow width is 20cm～40cm, the long 2m～10m of ditch, and the spacing of ditch and ditch is 4m～8m.
The improvement method that ground is administered in desertification comprises the following steps:
The first step: choose sand control region and determine patch position, gallery position, utilize gallery that these patches are coupled together, and then formation matrix, the integral body that constantly contacts and develop on patch-gallery-matrix Shi Yige space, being applied in the improvement ground that desertifies and large-area sandy land will being broken the whole up into parts exactly, according to this theory of landscape ecology, rebuild the ecosystem of degraded land, reach the administration way fanning out from point to area, the distance between patch is determined according to desertify ground size, expansion rate and treatment cost;
Second step: offer several ditches on each patch and gallery, require the orientation of ditch and the dominant direction of winter-spring season vertical, so more contribute to reach regulation effect;
The 3rd step: filling soil and cow dung barnyard manure mixture in ditch, filler is from costa colpi 4cm～5cm, and in ditch, broadcast sowing the seeds that grass seeds or cuttage locality are easy to survive, and then on the ditch surface of broadcasting sowing grass seeds, spread the thick sand of paving 1cm～2cm, reach the demand of water conservation.
Advantage of the present invention is as follows:
1, considered that the ground treatment cost that desertifies is high, with currently available technology measure, can not meet improvement needs, the acquisition of soil is to be relatively easy to, and operational feasibility of the present invention is higher.In the desertification ground control that research is found to carry out the Northwest, ， river, original control measures basically a lot of methods does not reach the effect of improvement.Be on the one hand due to treatment cost problem, no matter be fence fencing, braiding sand-protecting barrier, plant tree seedlings and spreading etc., all need very high cost to drop into.These inputs can not be brought larger ecological benefits.The cost dropping into, after the Large Scale Death along with the seeds of planting, becomes nihility at winter-spring season under a gale is blowing.Desertify in the on-site inspection of ground regulation effect and find in Chuan northwest, the plateau red building of planting is large portion is dead then, only remaining fragmentary several.Remaining minority plant also under the scorching of burning sun, withered very soon under the degrading of dust storm.
2, the present invention has considered the characteristic of soil self from the beginning, has the ability of water-retention fertilizer, gives full play to the inherent characteristic of soil.Make it in desertification ground, keep liquid manure, to vegetation growth, provide better habitat.Research discovery, the existence on large area desertification ground, does not live liquid manure because desertify itself to stay exactly.A lot of husky raw vegetation only have to utilize and complete of short duration rainy season its whole history of life.
