Abstract
The utility model discloses the weeding composite mulching film that a kind of energy is ventilative.The weeding composite mulching film that a kind of energy be composited by the reflective membrane on upper strata and the weed removal mulch film of lower floor is ventilative, ground membrane body is provided with uniform, fine and closely woven ripple parallel with width along its length; The cross section of ripple is triangle, trapezoidal or arc; The length of ripple and be highly respectively 0.5-5mm.Owing to adopting above-mentioned ripple struction, the utility model can while reflected sunlight, and enter soil with guaranteeing extraneous smooth air, the heat in soil distributes swimmingly, thus is conducive to crop root and soil beneficial microorganism normal metabolic activity.Be particularly suitable for the weeding operation of summer high temperature time.
Description
Technical field
The utility model relates to agricultural mulching technical field, the weeding composite mulching film that especially a kind of energy is ventilative.Be particularly suitable for the weeding operation of summer high temperature time.
Background technology
Weed removal mulch film covers the object mainly being reached weeding on the ground by the photosynthesis of isolated sunlight, blocking-up weeds.Because weeding composite mulching film is black, air-locked film, open and flatly behind ground, form sealant, on the one hand, extraneous air cannot enter soil, can cause soil anoxic; On the other hand, the heat energy that the film absorption of black is a large amount of also passes to soil, and the heat in soil cannot be distributed by weeding composite mulching film, particularly in the summer high temperature time, very easily causes the temperature in soil too high.These two kinds of situations have all had a strong impact on crop root and soil beneficial microorganism normal metabolic activity.
At present, the heat energy that the film absorption for black is a large amount of also passes to the negative effect of soil, in the production practices of orchard mulch film weeding, takes the method covering one deck reflective membrane on weed removal mulch film.Due to reflective membrane energy reflected sunlight, significantly reduce the weed removal mulch film of lower floor to the absorption of heat energy, the Photosynthetic Efficiency of fruit tree can also be strengthened simultaneously.
Utility model content
The purpose of this utility model be to provide a kind of can while reflected sunlight, the heat entered in soil, soil distributes, is conducive to the weeding composite mulching film of crop root and soil beneficial microbe normal metabolic activity swimmingly with guaranteeing extraneous smooth air.
The technical solution of the utility model is: the one be composited by the reflective membrane on upper strata and the weed removal mulch film of lower floor is breathed freely weeding composite mulching film, and described ground membrane body is provided with uniform, fine and closely woven ripple parallel with width along its length.
The cross section of described ripple is triangle, trapezoidal or arc.
The length of described ripple and be highly respectively 0.5-5mm.
Owing to adopting above-mentioned ripple struction, the utility model can while reflected sunlight, and enter soil with guaranteeing extraneous smooth air, the heat in soil distributes swimmingly, thus is conducive to crop root and soil beneficial microorganism normal metabolic activity.Be particularly suitable for the weeding operation of summer high temperature time.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of the concrete structure according to a kind of ventilative weeding composite mulching film that the utility model proposes.
In figure, 1 is ripple, and 2 is reflective membrane, and 3 is weed removal mulch film.
Embodiment
Below in conjunction with embodiment, the utility model is described further.
Embodiment: as shown in Figure 1, the weeding composite mulching film that a kind of energy be composited by the reflective membrane 2 on upper strata and the weed removal mulch film 3 of lower floor is ventilative, weeding composite mulching film is provided with uniform, fine and closely woven ripple 1 parallel with width along its length.
The cross section of ripple 1 is triangle.
The length of ripple 1 and be highly respectively 3mm.
Claims (3)
1. the weeding composite mulching film can breathed freely, is composited by the reflective membrane (2) on upper strata and the weed removal mulch film (3) of lower floor, it is characterized in that, described weeding composite mulching film is provided with uniform, fine and closely woven ripple (1) parallel with width along its length.
2. the weeding composite mulching film that a kind of energy according to claim 1 is ventilative, it is characterized in that, the cross section of ripple (1) is triangle, trapezoidal or arc.
