Abstract

The utility model relates to a water-collecting reflecting concrete mulching film. The utility model uses a concrete component to replace the existing plastic thin film, and achieves the purposes of water collection, soil moisture preservation, light enhancement, wind resistance, hail resistance, heat insulation, freezing resistance, grass suppressing, and fertilizer protection, through the funnel-shaped model and a surface white reflecting coating layer. The concrete mulching films are covered on the soil block by block, the crops and the plants are grown from holes of the funnel. When the crops and the plants are ripened and harvested, the next crops are planted in the holes of the funnel. The utility model can be durably and repetitively used.

Description

The reflecting concrete mulch film catchments

The utility model relates to a kind of agricultural cladding system that slows down the soil moisture evaporation, especially can gather the concrete mulch film of rainwater, reverberation photograph.

At present, known agricultural mulching material is the polyethylene plastic film, though plastic film also can slow down the evaporation of soil moisture, but still have following defectives: 1. wind loading rating is poor, and suitable application region is limited; 2. easily battered down, the bad adaptability of meteorologic factor by the hail puncture; 3. weeds can't be shoveled hoe under the film, have wasted a part of soil fertility; 4. natural rainwater can not effectively enter in the film, causes the film external shunt to lose, and has reduced the water content in soil; 5. the temperature difference outside the film inner membrance is too small, and insulating power is limited, is difficult for resisting stronger cold current; 6. the reflective rate differential of plastic film outer surface is difficult to strengthen the efficient at sunshine of crop; 7. can not be repeated repeatedly to use, whenever change one batch of crop, must newly purchase mulch film one time, increase agricultural cost; 8. Fei Qi mulch film fragment is difficult for degraded, causes new white pollution.In the face of above defective, also do not find out a kind of scheme of overall solution now.

The purpose of this utility model provides a kind of mulch film, and it can not only slow down the evaporation of soil moisture effectively, and have the anti-hail of wind resistance, the soil moisture conservation of catchmenting, reflective increase photograph, insulation freeze proof, press down grass and protect fertile, the durable and the advantage of contaminated land not.

The purpose of this utility model is achieved in that the main material that at first upgrades mulch film, casts squarely funnel-form concrete component with cement, sandstone, coats reflecting rate at external surface of structural member then and reaches 90% whitewash.Piece of this concrete mulch film is covered on soil, substitute original agricultural plastic film.Crop plant grows, grows until maturation in funnel-form concrete mulch film mesopore, plants the next round crop after the results again in former funnel mesopore.

The utility model is described in further detail below in conjunction with accompanying drawing: 1. concrete mulch film film bodies, 2. white reflection coating, 3. funnel mesopore among the figure.

In the accompanying drawings, concrete mulch film film body (1) top is high, the low funnel-form inclined-plane, middle part of periphery, natural rainwater can be imported funnel mesopore (3), and seepage flow advances in the soil of bottom to store, and plays the effect that the natural rainwater of collection is irrigated plant root.Because white reflection coating (2) can reflect 90% natural daylight, has strengthened the photosynthesis on crop blade face, the demand of compensation plant counterglow.Because this ground film body is a main material by concrete, its quality is heavier, is difficult for being turned over by wind, and the effect of anti-high wind is arranged; Its thickness is bigger, is enough to bear the bump of hail, and better heat-insulating property is arranged, and improves the ability that crop root is resisted frost; Its sound construction can be reused enduringly; The mulch film housing is light tight, can guarantee that the weeds in the film are not long, has the function of hoeing up weeds automatically concurrently.

Since the utility model can make plant in the desert, Gobi desert, exposed slope regain growth conditions, to the conservation of soil and water, improve the ecological environment etc. in exploitation desert territory, irreplaceable positive role is arranged.

Claims

1. the reflecting concrete mulch film that catchments, it is characterized in that: concrete funnel shaped member surface has reflecting coating, has the funnel mesopore.
