Description
Technical field
the utility model relates to without irrigating sacsaoul growing area guard technology field, is a kind of structure improved without irrigating sacsaoul growing area snowmelt infiltration rate.
Background technology
the restoration and reconstruction work in current China's desert forest land is mainly adopted in two ways.One relies on natural self-recovery, but due to clear-cutting forestland area, ecotope is abnormal severe mostly, clear-cutting forestland mode is very difficult, another kind be adopt irrigate and without plants such as irrigation method artificial planting sacsaoul, Chinese tamarisk and salix monogolicas, irrigation method is adopted to there is the bottleneck problems such as the high and water consumption of mu input cost is large, not easily spread, and adopt the bottleneck problem that there is poor growth and preservation (surviving) rate very low (≤10%) without the artificial live seedling of irrigation method and transplanted seedling.On-site inspection and research show that moisture is the basic reason causing Haloxylon Plant death.When the water content of subterranean depth 30cm to 60cm sand bed is greater than 2%, sacsaoul growth better; As the water content <2% of 1%< sand bed, sacsaoul existence only can be maintained, its growth retardation; As the water content <1% of sand bed, sacsaoul seriously becomes feeble and die, the critical value 2% of the content of the required moisture of sacsaoul growth, and therefore, the water content how improving sacsaoul growing area 30cm to 60cm sand bed improves the key point of sacsaoul survival rate.
for Desert Area, Seasonal Snow Cover melt water and rainwater are the topmost Source Of Supplies of desert Forest Soil Moisture, and precipitation size, precipitation form and time devided modulation etc. directly affect the reallocation of moisture in soil.Find by observing winter, the distribution of areal snow also there are differences, and the difference of flat area is little, and the ground such as sand dune longitudinal dune differ greatly, be mainly reflected in following aspect: 1, longitudinal dune top in sand dune makes accumulated snow herein thinner due to the aggtegation of wind-force, does not even have; 2, the luvisde Snow Thickness in sand dune longitudinal dune slope is lower than lee face; 3, under sand dune longitudinal dune slope higher than mesoslope top, slope.The thickness of accumulated snow determines the abundant degree of water resource, also reflects in slope relative deficient with the water resource on top, slope from the side, in dune slope, plant the survival rate of sacsaoul well below the survival rate of planting sacsaoul under slope with top, slope.
as everyone knows, when accumulated snow enters spring and reaches snow melt point, accumulated snow starts to melt, in snow melting process, topsoil exists to melt and freezes phenomenon daytime night, the soil surface temperature at phase of infiltrating at each noon day can rise to rapidly 0 DEG C by-0.5 DEG C to-1.2 DEG C, earth's surface accumulated snow melt water infiltrates period, melt water in snow deposit infiltrates bottom accumulated snow with the form of finger-like stream, freeze night to form anchor ice water blocking layer at the interface of accumulated snow and soil, next day, when being seeped into bottom snow deposit under snowmelt, can being trapped in interface and forming local high aquifer formation, along with the thawing of water blocking layer is just oozed down gradually.Constantly infiltrating of snowmelt makes topsoil be tending towards saturated, and the increase of moisture content and congelation at night can reduce again the effecive porosity of topsoil, makes infiltration rate reduce and form water blocking layer.Therefore, the snow melt rate in a certain moment on daytime is much larger than being greater than soil infiltration rate, and cause snowmelt meeting along slope toward dirty, under frozen soil condition, infiltrating of snowmelt is extremely complicated process, is also the key link that snowmelt supplements soil moisture.Further, after snowmelt enters soil, due to the decline of nocturnal temperature, this place's Zinc fractions freezing soil, the rate of relative steady infiltration of freezing soil is about about 1/10 of non-freezing soil, frozen soil to subtract the effect of oozing very remarkable.Under freezing condition, in soil, operative liquid aqueous phase becomes solid ice, and the content of solid ice can increase gradually along with the reduction of temperature, and by occupying soil part water guide hole, the discharge section area of current of making to infiltrate reduces, and thus makes the hydraulic conductivity of soil reduce.As can be seen here, the merging into nature under natural conditions is also cause one of root that in dune slope top and slope, moisture content is low.
we find in practice process: irrigate in sacsaoul growing area in nothing, the sacsaoul survival rate of 1 year to 2 years presents the rule on top, > longitudinal dune slope in > longitudinal dune slope under longitudinal dune slope, learn in this habitat of longitudinal dune through experimental analysis, the trend on top, > longitudinal dune slope in > longitudinal dune slope under longitudinal dune slope is there is in the degree of depth in the water content of 30cm to 60cm longitudinal dune, especially in the rapid deterioration phase of moisture in June to August, it is more obvious that the soil moisture content that in longitudinal dune slope and longitudinal dune slope is pushed up declines, it can thus be appreciated that moisture affects the key reason with the young phase survival of top, longitudinal dune slope sacsaoul in longitudinal dune slope.And in snow melt season due under the impact of aqueous water phase transformation and anchor ice water blocking layer makes the snowmelt of rockier ridge (sand dune) middle and upper part flow to longitudinal dune slope, improve the soil moisture content under longitudinal dune slope, under the longitudinal dune slope that this makes, the water content of soil 30cm to 60cm is more, and the water content on top, in longitudinal dune slope and longitudinal dune slope is lower.Further, along with the increase of the sacsaoul age of tree, lower floor's radical is increase trend.The sacsaoul root system growing 1 year is mainly distributed in 0cm to 20cm soil layer, accounts for about 64% of total radical; The root system growing 2 years is in the majority at 20cm to 60cm soil layer, accounts for about 65%; The root system growing 3 years in 40 below cm soil layers Root Distribution up to about 88%.Grow 1 year mainly to concentrate in 30cm to 60cm to the sacsaoul root system in 3 years, it can thus be appreciated that, improve sacsaoul pushes up the survival rate of 1 year to 2 years in longitudinal dune slope problem with slope, be just converted into the problem how improving soil water content in 30cm to 60cm depth bounds in top, longitudinal dune slope and longitudinal dune slope.
