Abstract

The utility model relates to a novel containing water-preserving sand-fixation afforesting brick comprising brick body, wherein the outside surface of the brick body is equipped with botanical planting holes which are round, square or shapeless blind holes or the upper-lower communicating holes, the outside surface of the brick body is covered with thermal insulation ground sheeting, the cross section of the brick body is rectangle, square or trapezoid, the internal portion of the blind holes or the upper-lower communicating holes is equipped with nourishing soil layer. The utility model has the following beneficial effects: firstly material needed is easy to get, preparation method is easy and feasible, and products can break down naturally with no pollution, and is good for environment, secondly the brick can provide water and nutrient need for plants with enduring effect can solve the process of desert encroachment effectively, thirdly the botanical planting holes have greenhouse small climate environment, thus reducing temperature difference between day and night, thereby achieving the effect of heat preservation and humid preservation, fourthly the usage is convenient, and the cost is low.

Description

The sand-fixing greening brick that contains water-loss reducer

Technical field

The utility model relates to a kind of novel sand-fixing greening brick that contains water-loss reducer.

Background technology

The land area that is subjected to desertification influence on the earth has more than 3,800 ten thousand square kilometres, and at present, the whole world has 6,000,000 hectares of soil generation desertifications every year approximately.Sandstorm increase since the nineties in last century and the northern area of China ecological degeneration, the diffusion of desertification land large tracts of land have direct relation.The average annual expansion rate of the northern area of China desertification land, enter the nineties in last century after, with annual 2460 square kilometres speed in expansion.Desertification causes heavy losses for agricultural, animal husbandry and the people's lives property of many countries and regions.China is subjected to one of the most serious country of desertification hazard in the world, and the area of annual desertification land is up to sq-km more than 3000, and the annual direct economic loss that causes because of desertification is above 54,000,000,000 yuan.Therefore, find a kind of effective desert control method, reduce the economic loss that causes because of desertification, become national even global problem.The desert treatment method of utilization mainly contains planting trees and grass, conceding the land to forestry, chemical sand-fixing etc. in the world at present, though these methods all have certain effect, exists deficiency in various degree:

(1) planting trees and grass, methods such as conceding the land to forestry: in the past few decades, preventing and controlling have dropped into a large amount of manpower and materials to desertification in country, continue to have implemented northwest-north-northeast China networks of shelterbelts engineering, defend and control sand engineering and project on treatment of sources of sand in Beijing and Tianjin etc. have been started, because the desertification of China 90% area annual rainfall is below 400 millimeters, except that local moisture condition preferably the place, all do not reach " afforestation " required condition, recent studies have shown that, 10% the desertification land of only having an appointment has obtained improvement, 12% desertification land has obtained recovery in various degree, the state of " the local reverse; the whole deterioration " does not obtain radical change, and the desertification situation is still severe.

(2) chemical sand-fixing: mainly contain cement paste class, water glass class, oil product class and high molecular polymer class etc., but adopt the shortcoming of these methods have cured layer intensity low and thin, solidify and not exclusively, easily cause secondary pollution, ageing resistace difference etc.

Summary of the invention

Problem to be solved in the utility model is to propose a kind of sand-fixing greening brick that contains water-loss reducer at above-mentioned prior art, and it is simple in structure, and the suction water retaining capacity is good, and afforestation effect is good, and can not cause other influences to environment.

The technical scheme that its technical problem that solves the utility model adopts is: the sand-fixing greening brick that contains water-loss reducer, include the brick body, it is characterized in that described brick body upper surface is provided with the plant growing hole, described plant growing hole is blind hole or the through hole that is communicated with up and down.

Press such scheme, described blind hole or the through hole that is communicated with up and down are circular or square or other random figures.

Press such scheme, described brick body upper surface is coated with Insulation Mulch Film.

Press such scheme, described brick body cross section is rectangle, square or trapezoidal.

Press such scheme, described blind hole or the through hole inside that is communicated with up and down are provided with the nutrition soil layer.

Brick body of the present utility model adopts loam, water-loss reducer, plant straw stalk, adhesive to mix compacting and form, and in concrete preparation process, we can also add organic fertilizer, in order to plant grass seeds or seeds are carried out replenishing of nutrition.Insulation Mulch Film, we adopt be can natural degradation mulch film, can play the effect of heat and moisture preserving to growth and development of plants, accelerate the plant growing process, improve survival rate.

The beneficial effects of the utility model are:

1) material requested obtains easily, and the preparation method is simple, but and the product natural degradation, pollution-free, help environmental protection;

2) the long-acting demand of plant to nutrient and moisture that provide can effectively solve the desertification process;

3) the plant growing hole has the greenhouse microclimate environment, reduces day and night temperature, has the heat and moisture preserving effect;

3) easy to use, with low cost.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, the sand-fixing greening brick that contains water-loss reducer, include brick body 3, described brick body is a cuboid, its high 60～200mm, long 240～1000mm, wide 50～200mm, described brick body upper surface is provided with plant growing hole 1, and the plant growing hole is a blind hole, the distance of blind-hole bottom and brick body soffit is 20～50mm, described blind hole can be circular, square regular or random figure, and described blind hole or the through hole inside that is communicated with up and down are provided with nutrition soil layer 2, contain organic fertilizer in the nutrition soil layer, loam and water-loss reducer, plant grass seeds or seeds can be imbedded wherein.The brick body adopts loam 55%, water-loss reducer 10%, plant straw stalk 25%, adhesive 10% to mix compacting and form, and in concrete preparation process, we can also add an amount of organic fertilizer, in order to plant grass seeds or seeds are carried out replenishing of nutrition.Described brick body upper surface is coated with Insulation Mulch Film, we adopt be can natural degradation mulch film, can play the effect of heat and moisture preserving to growth and development of plants, accelerate the plant growing process, improve survival rate.Described in actual use brick body cross section can also be square or trapezoidal or other regular or random planes.
