Abstract
The utility model relates to a mulching film, which is an integral structure adopting transparent and non-transparent films which are arranged along the length direction in a longitudinal and alternate way according to a certain width. The mulching film is characterized in that an integral structure with transparent and opaque alternately arranged is adopted, the effects of heat preservation, soil moisture preservation and fertilizer efficiency maintenance can be achieved for seedlings on ridge platforms, the growth of weeds in furrows can be inhibited, manual weeding is not needed during mulching, manpower and cost are saved, the opaque part is of a composite structure with an upper white film and a lower black film, the upper film has a reflection effect on sunlight and does not absorb heat, and therefore the phenomenon that the growth of crops is affected due to overhigh ground temperature caused by the arrangement of the black film is avoided.
Description
The utility model relates to the protective cover of a kind of plant, particularly can be incubated, preserves soil moisture and suppress the mulch film of weed growth.
General mulch film mostly is a transparent plastic film, and it only has insulation, soil moisture conservation function, does not have the function that suppresses weed growth.Also have in manufacturing the raw material of plastics film and dose weedicide, make it in degradation process, bring into play weeding usefulness, but that shortcoming is a cost is higher.
The purpose of this utility model is to provide a kind of both had insulation, soil moisture conservation function, can suppress the mulch film of weed growth again.
The purpose of this utility model is achieved in that the difference of this mulch film and prior art is that mulch film is to adopt the transparent integrative-structure of vertically alternately arranging along its length by certain width with opaque coating.What wherein opaque coating adopted is to go up white black dichromatism film composite structure down.The transparent width ratio with opaque section of the utility model determines that according to row spacing promptly opaque section should be corresponding with the furrow width, and transparent part is then corresponding with ridge platform width.The white films on opaque section top has reflex action to sunlight, and does not absorb heat, and the black film of bottom is light tight, and therefore, the furrow that opaque section covers can suppress the growth of weeds because of loseing light and temperature is low.
Characteristics of the present utility model are: adopt the transparent integrative-structure of alternately arranging with opaque coating, the effect that can play insulation, soil moisture conservation to the seedling on the platform of ridge and keep fertilizer efficiency, the growth of weeds in the furrow be can suppress again, during overlay film,, manpower and expense saved without artificial weeding; Opaque section adopt to be gone up white black dichromatism film composite structure down, and last film has reflex action to sunlight, does not absorb heat, thereby can not cause that surface temperature is too high to influence plant growth because of the setting of black film.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional view of the present utility model.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, mulch film of the present utility model is a sealed polyethylene plastic, and it is made of transparent film (1) and opaque coating (2) two portions of vertically alternately arranging along its length and be connected as a single entity.The width of transparent film should be corresponding with the ridge platform width that is covered, and the width of opaque coating should be corresponding with the furrow width that is covered.What opaque coating adopted is to go up white (3), down black (4) dichromatism film composite structure.This mulch film can be produced with three-layer co-extruded plastic membrane blowing device.
Claims (2)
1, a kind of mulch film is characterized in that this mulch film is for adopting the transparent integrative-structure of vertically alternately arranging along its length by certain width with opaque coating.
2, mulch film according to claim 1, what it is characterized in that the opaque coating of mulch film adopts is to go up white, black dichromatism film composite structure down.
