Abstract

A process for fixating and transforming desert and planting plant is characterized by that the powdered semi-hydrated gypsum or anhydrous gypsum, which can be hydrated by rain or sprayed water, is spread on the surface of desert, and then mechanically mixed with surface sand and pressed.

Description

A kind of gypsum fixes the sand sand control and afforests and beautifies the new technology of sand desert

The present invention relates to a kind of semi-hydrated gypsum or anhydrous plaster powder utilized and fix the sand, afforest, transform a kind of new technology of beautifying the desert, belong to agricultural and general field such as herd.

Traditional and existing sand-fixation method mainly is to adopt wheat straw grid method, plant grass, tree planting and hedge fix the sand, methods such as the chemical agent surface seepage fixes the sand, wherein to fix the sand be that the wheat straw shovel of spending money is inserted the grid that the surface, sand dune forms a determining deviation to the wheat straw grid, fix the sand within the specific limits, because weathering, this method is held time shorter, it is a kind of best sand-fixation method that the planting grasses and trees greening is fixed the sand, but moisture content is difficult to keep in the desert, planting grasses and trees is withered easily dead, it is to form paravent within the specific limits to fix the sand that hedge fixes the sand, but it is not have to draw in thing that large tracts of land is checked winds and fixed drifting sand, it is to utilize the infiltrative chemical adhesive of a kind of tool to send forth on the surface, sand dune to make surperficial sand be bonded to the purpose that cap rock reaches curing through osmosis that the Chemical Felter infiltration is fixed the sand, although but this method large tracts of land is promoted the use of, but written or printed documents cost height, the material gas permeability is poor, is not easy to development of plants.

The purpose of this invention is to provide a kind of can fixing the sand; the new technology concrete grammar that can afforest a kind of sand-fixing greening desert for the treatment of both principal and secondary aspect of disease again is to utilize semi-hydrated gypsum or hard burnt plaster; or industry by-product gypsum is gone into the desulfurized gesso of flue gas ardealite; fluorgypsum; citric acid gypsums etc. are through drenching with rain or manually spraying behind the certain water gaging in sand dune surface; directly be sprinkled into the surface, sand dune through land plaster; with artificial or machinery land plaster is being mixed in the grains of sand; make the husky mixture compacted of the good gypsum of blending with the mechanical nip roll or the mode of manually patting compacting then; can cause difformity according to different situations; as artificial aisle; the husky mixed layer of gypsum; see Fig. 1; greenbelt can form latticed, sees Fig. 1, and channel of approach can design relevant position and see Fig. 2; make the surface, sand dune form one and carry out cap rock, the grid or the irregular clathrate grid ridge that can be designed to inclined ladder shape on the cap rock by isohypse.The bottom is big, and top is little, rain is stored and through the permeability hole infiltration in inside, sand dune, tiling and go up the thin mould of plastics in the permeability hole top layer, opens an aperture in the middle of the surface, and grass can be planted in the inside, plant tree, add that gypsum is again according to thermal insulation being arranged, the function that suction discharges water, can preserve moisture, can prevent from again to be exposed to the sun, distribute moisture content, help protecting sand, fixed dune moves simultaneously, just can accomplish both to fix the sand, greening again, the sandstorm that prevents and controls desertification, the double purpose extremely of sample.

Figure of description is as follows

Accompanying drawings embodiment is as follows:

Present embodiment is: utilize semi-hydrated gypsum (comprising the semi-hydrated gypsum that semi-hydrated gypsum that the plaster of paris is made and chemical synthesis gypsum are made) and hard burnt plaster in desert area; sprinkling a certain amount of land plaster on the sand dune behind the rain or on the sand dune behind the artificial diversion spray; then manually with toothed sacrificial vessel or toothed machinery; land plaster is mixed with the grains of sand that contain a certain amount of moisture content; utilize the gypsum hydration mechanism to make the surface, sand dune form a gypsum sand mix shell in the short period of time; see Fig. 1 (1); when making shell; artificial shape by the sand dune; make the lattice ridge (2) of trellis or strip; also can set up walkway (3) in the certain limit on lattice ridge supplies; gutter (4); or draw contour thread ground, sand dune ridge (5); rainwater is drawn land ridge to flow into the permeable hole by the lattice ridge of the infiltration hole (7) in the thin mould (6) of plastics in the lattice ridge water infiltration is made layer of preserving moisture of bottom formation in the cap rock bottom; planting trees and grass in the hole; the water supply of plant is provided; the water conservation layer; thereby reached and fixed the sand kind of a grass; plant tree; fix the sand; greening again; beautify control sandstorm and desertification, the purpose for the treatment of both principal and secondary aspect of disease.

With the method sand-fixing greening desert, the one, utilized the characteristic of gypsum fast solidifying to make the surface, sand dune form shell, work the effect of checking winds and fixing drifting sand, the 2nd, utilize gypsum suction, the moisture absorption can discharge water again, moistureproof, performance that can also thermal insulation can provide the environment of insulation to plant production, has play a part to keep and supply moisture content for plant growing again.Also, can reflect solar glare, prevent water evaporates, keep the ecological environment benign development because of gypsum tool white.Also available gypsum adds the grains of sand and makes difform fragment of brick when administering, and builds house or anthropogenic landscape, views and admires for human living.

Claims

1. one kind is utilized semi-hydrated gypsum or anhydrous plaster powder to add a small amount of Admixture to fix the sand a kind of new technology of Chinese afforestation desert; it is characterized in that; utilize semi-hydrated gypsum or anhydrous plaster powder hydrating capacity sprinkling a certain amount of land plaster on the sand dune behind the rain or on the sand dune behind the artificial diversion spray; then manually with toothed farm implements or toothed machinery; land plaster mixed with the grains of sand that contain a certain amount of moisture content press solidly; make the surface, sand dune form a gypsum sand mix shell in the short period of time, can cause difform lattice ridge simultaneously; passage; the ditch; building and desert view thereof.In the lattice ridge, leave permeability hole; The thin mould of plastics can be laid in the permeability hole surface, and the thin mould of plastics is provided with permeability hole, can plant trees in the permeability hole.Keep the ecological environment benign development.Also available gypsum adds the grains of sand and makes difform fragment of brick when administering, and builds house or anthropogenic landscape, views and admires for human living.
