Description

Desert sand-fixing greening device

1, technical field

The utility model belongs to method of tackling desert field, is specifically related to a kind of device every barrier formula sand-fixing greening.

2, background technology

In a lot of areas, the edge in desert is in continuous expansion, and mobile quick sand just promptly corrodes, engulfing large stretch of soil.Along with being on the rise of desertification of land, the natural calamities such as arid, sandstorm also occur again and again.People adopt various measures always and carry out the improvement of desertification of land.The method of checking winds and fixing drifting sand at present has following several:

Place obstacles.Mainly contain straw checkerboard barrier barrier, clay sand-protecting barrier, hedge sand-protecting barrier, vertical sand barrier, tiling sand-protecting barrier etc., straw checkerboard barrier sand-protecting barrier is used the materials such as wheat straw, straw, reed on mobile sand dune, to be bundled into windbreak, to weaken the erosion of wind-force, there is the effect of rainfall interception simultaneously, can improve the water content of sand bed, be conducive to the growth of psammophytes.Clay sand-protecting barrier is clay to be piled on sand dune to the low bank of earth between fields of high 20 ~ 30cm, and spacing 1 ~ 2m moves towards vertical with wind direction, and clay fixes the sand construction simply, and sand-fixing effect is good, and has good water retention capacity, but needs a large amount of clays.

On Shamian Island, cover fine and close thing.Israel attempted a kind of method that plastic film fixes the sand, and was about to plastic film and covered on desert, and push down with stone weight.This method can effectively stop moisture loss, but plastic film easily sweeps by wind, and its forfeiture is fixed the sand and water retaining function, causes secondary pollution simultaneously.

Utilize waste plastics Desert Control.The method can play fixes the sand and water retention.Utilize simple process, modified waste plastics is become and fixes the sand cementing material, then at graft water quality face around, spray one deck and fix the sand cementing material, after 15 ~ 20 minutes, fix the sand cementing material just that top layer sand is cemented together, form stickiness and fix the sand layer, sand bed is flexible, is difficult to cracking, and fixes the sand layer and closely cohere by fixing the sand cementing material and top layer sand, weight is larger, and strong wind is also difficult to be swept.

Various desertification control methods are generally all in conjunction with plant in treating and water resource utilization.Plant in treating refers to desert area sowing psammophytes, to stop Desert Expansion and to improve ground, desert, psammophytes has moisture and sends out few, supporting tissue, the features such as conducting tissue prosperity, can resist blast attacks, and as early as possible moisture and nutriment are transported to and need organ badly, in its cell, often keep higher osmotic pressure, there is very strong lasting water absorbing capacity, make plant be difficult for dehydration, the environment that can adapt to drought, its improvement method: 1, the planned cultivation of desert area psammophytes, make sand-fixation forest, generally on the windward slope of sand dune, to plant short shrub or herbaceous plant, admittedly live the loose grains of sand, on leeward slope low-lying land, plant tall trees wood, stop sand dune movement.2, in desert edge area, make wind break, to weaken the wind-force of desert area, stop Desert Expansion, the effect of wind break is relevant with forest belt height, and the taller and bigger protection effect of trees is better, relevant with ventilative performance with the density structure of trees in addition, its type has 3 kinds, tight type forest belt, sparseness structure forest belt and aeration structure forest belt, the effect of plant in treating focuses on selecting the forest belt structure of suitable seeds and science.

Water resource is utilized the most important in control of desert process, and the water source in desert mainly contains underground water, river course water and precipitation, but desert areal precipitation is unstable, generally the variation with weather changes, moistening time precipitation is many, and dry warm time precipitation is few, and desert underground water is stable, its sand bed is thick, there is certain thermal insulation, water is able in underground preservation, but this stablizing is relative, be subject to the restriction of precipitation, solve water resource mainly from the viewpoint of paddling, water delivery and water saving, irrigation etc.

The basic skills control desertifying is fixed the sand exactly, reduces flowing of quick sand, fixing soil on this basis, serike.At present the more effective and simple of Desert Control, sand-fixing greening is the mode of placing obstacles, but existing straw checkerboard barrier barrier, clay sand-protecting barrier, hedge sand-protecting barrier, vertical sand barrier and tiling sand-protecting barrier etc. have some shortcomings part, as be subject to resource limitation, speed is slow, when the object plane of planting is long-pending large, pouring is effort relatively, and water consumption is large.

3, summary of the invention

The purpose of this utility model is to provide a kind of desert sand-fixing greening device, to overcome existing deficiency of fixing the sand form, can complete fast and efficiently sand-fixing greening task, can improve the survival rate of serike, and save a large amount of water sources and manpower.Utilize fully rainwater, the plant of planting can fully be grown, play the object of sand-fixing greening, improvement soil, increase usable land.

The technical solution adopted in the utility model is: the elementary cell of desert sand-fixing greening device is the rectangular frame with four frames, has the tow of evenly arranging on framework; Four frame inside at rectangular frame are provided with water pipe, in frame outside, have water pipe head, and the water pipe head of each elementary cell can interconnect; A plurality of elementary cells interconnect, and form large-area sand-fixing greening device, can cover large stretch of sandy land.

The utility model adopts and interconnects sand-fixing device in blocks, can complete fast and efficiently large area desert sand-fixing greening, improve greatly check winds and fix drifting sand ability and afforestation effect, improvement soil, large area increases usable land, in conjunction with mechanized construction can be larger improve speed and efficiency, its application makes the city or the rural area that desert are become to an inhabitation people become possibility, people's life condition is improved, increased the area of ploughing, improve natural environment and climate, reduced sand and dust, purified atmosphere.Its application prospect is fine, meets current social and the people requirement that improves to environment and life.The utility model device can be repeatedly used, and saves investment.
