Description

Desert sand-fixing greening device

1, technical field

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

2, background technology

In a lot of area, the edge in desert is in continuous expansion, and the quick sand of flowing just promptly corrodes, engulf 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., checked sand hinder straws uses the materials such as wheat straw, straw, reed to be bundled into windbreak on the sand dune of flowing, to weaken the erosion of wind-force, there is the effect of rainfall interception simultaneously, the water content of sand bed can be improved, be conducive to the growth of psammophytes.Clay sand-protecting barrier is low bank of earth between fields clay being piled on sand dune 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.

Shamian Island covers fine and close thing.Israel attempted a kind of method that plastic film fixes the sand, and by covered rearing with plastic film on desert, and pushed down with stone weight.This method effectively can stop moisture loss, but plastic film is easily swept by wind, makes it lose and fixes the sand and water retaining function, cause 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 the water quality face around graft is sprayed one deck and is fixed the sand cementing material, after 15 ~ 20 minutes, fixes the sand cementing material just by cemented together for top layer sand, 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 comparatively large, and strong wind is also difficult to be swept.

Various desertification control method generally all utilizes in conjunction with plant in treating and water resource.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 is flourishing, blast can be resisted attack, and moisture and nutriment are transported to need organ badly as early as possible, often higher osmotic pressure is kept in its cell, there is very strong lasting water absorbing capacity, make plant not easily dehydration, the environment of drought can be adapted to, its administering method: 1, sand-fixation forest is made desert area planned cultivation psammophytes, generally plant short shrub or herbaceous plant on the windward slope of sand dune, admittedly live the loose grains of sand, leeward slope low-lying land is planted tall trees wood, stop sand dune movement.2, wind break is made in desert edge area, 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 the Shelterbelts structure selecting suitable seeds and science.

Water resource utilizes the most important in control of desert process, and the water source in desert mainly contains underground water, urban river water and precipitation, but desert areas precipitation is unstable, generally change with the change of weather, moistening time precipitation is many, and dry warm time precipitation is few, and desert underground water is stablized, its sand bed is thick, there is certain thermal insulation, make water be able to preserve in underground, but this stablizing is relative, by the restriction of precipitation, solve water resource mainly from the viewpoint of paddling, water delivery and water saving, irrigation etc.

The basic skills controlling to desertify is fixed the sand exactly, reduces the flowing of quick sand, fixing soil on this basis, serike.The more effective and simple of current Desert Control, sand-fixing greening is the mode placed 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 limited by resource, speed is slow, when cultivation plant area is large, effort is compared in pouring, and water consumption is large.

3, summary of the invention

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

The technical solution used in the present invention is: the elementary cell of desert sand-fixing greening device is the rectangular frame with four frames, has the tow of evenly arrangement on framework; Be provided with water pipe in four frame inside of rectangular frame, outside frame, have water pipe head, the water pipe head of each elementary cell can be interconnected; Multiple elementary cell interconnects, and forms large-area sand-fixing greening device, can cover large stretch of sandy land.

The present invention adopts and is interconnected sand-fixing device in blocks, large area desert sand-fixing greening can be completed fast and efficiently, great raising is checked winds and fixed drifting sand ability and afforestation effect, improvement soil, large area increases usable land, speed and efficiency can be improved larger in conjunction with mechanized construction, its application makes desert to become the city of an inhabitation people or rural area becomes possibility, the life condition of people is improved, add the area in arable land, environmental protect and weather, decrease sand and dust, purified air.Its application prospect is fine, meets current social and the people improvement requirement to environment and life.Apparatus of the present invention can repeatedly use, investment reduction.
