Abstract
The utility model mainly relates to the field of ecological environment protection, in particular to a water-stopping seepage control device for desert greening, which comprises straw grid layers. A water-stopping anti-seepage layer is arranged above an original sand layer at a position 300mm to 900mm below a surface sand layer, a sand layer is arranged above the water-stopping anti-seepage layer, a permeable water-holding plant growth nutrition layer is arranged above the sand layer, and the straw grid layer is disposed above the permeable water-holding plant growth nutrition layer. The water-stopping anti-seepage layer is capable of stopping water directional flowing, and the water cannot disorderly seeps everywhere deep in the sand layer, so that water saving is achieved. Used materials are all green and environment-friendly and cannot pollute people and natural environment. Reasonably supplied water can be evenly supplied to green plants which can grow fast then, and thereby the problem of desert greening water and rainwater seepage are solved effectively. The water-stopping seepage control device is wide in application areas and convenient in regulated construction, can be used for greening deserts so as to green conditional deserts which can be greened, desert vegetation coverage is increased, and local ecological environment of the deserts can be improved.

Further, described sand bed thickness is 300～900mm.
Further, between described sand bed and water-permeable and water retention plant growing nutritive layer, also be provided with the straw plaited clathrum.
Further, the above and below of the described impervious barrier that blocks water is equipped with one deck thickening layers of kraft paper at least.
Further, the described heavy kraft paper that adds is high strength immersion oil thickening layers of kraft paper.
Further, the thickness of described water-permeable and water retention plant growing nutritive layer is 100～120mm.
Further, the described impervious barrier thickness that blocks water is 2～5mm.
The beneficial effects of the utility model are:
1, described a kind of multilayer that is used for afforestation desert impervious barrier material that blocks water, in the desert, use and to save a large amount of waters, on greening face, water, absorb by water-permeable and water retention plant growing nutritive layer earlier, redundance moisture content temporarily is seeped in the sand bed of bottom, owing to be provided with the impervious barrier that blocks water in the sand bed, the impervious barrier that blocks water has stoped the flow direction of water, water or else can be toward sand bed depths random everywhere seepage, thereby reaches water-saving purpose;
2, described a kind of multilayer that is used for afforestation desert impervious barrier material that blocks water all is environmental protections, can not pollute the Man ﹠ Nature environment;
3, described a kind of multilayer that is used for afforestation desert impervious barrier material that blocks water can reasonably distribute water supply, can supply with the used plant of greening uniformly, and plant can grow up fast.
4, described a kind of multilayer that is used for afforestation desert impervious barrier material that blocks water, it is extensive to have an application region, is convenient to the characteristics of scale construction.
Described a kind of multilayer that is used for afforestation desert impervious barrier material that blocks water, come the afforestation desert can be with this material with the desert afforestation of having ready conditions and to afforest, improve the desert vegetation coverage rate, can improve the ecotope of part, desert, can be in the desert planting forage grass, the medicinal material plant, the fruit plant, the grain plant allows the desert provide more resources for the mankind, sets up a kind of situation of harmony between man and nature.
