CN201440857U - Light-transmitting shading composite plastic film - Google Patents

Abstract

The utility model discloses a light-transmitting shading composite plastic film for covering crops, wherein a plurality of shading composite layers (1) are connected on the surface of one side of a film layer at intervals. The light-transmitting shading composite plastic film realizes the double functions of light transmission and shading, effectively guarantees the light-transmitting insulation and soil moisture in seedling stage of crops, and plays the role of partial shading when sunshine irradiates the plastic film with high intensity. The plastic film has two purposes, solves the weakness that users should hang a shading net over the plastic film when light intensity is strong in the prior art, and obviously reduces the labor intensity and production cost of crops plantation.

Description

The printing opacity compound mulch film that shades

(1) technical field: the utility model relates to agricultural mulching; Be specifically related to a kind of printing opacity that is used for mulch farming thing growth compound mulch film that shades.

(2) background technology: agricultural mulching of the prior art mainly is the covering that is used for interim insulation of crops growth of seedling and soil moisturizing.When the irradiation of the long-time high strength of daylight, the seedling plant overlay film under is prone to " day burning " phenomenon and withered.Lower as northern area April temperature, cultivation Da Jiang will carry out plastic mulching during seedling; When the daylight illumination of time-division at noon 5 to June is strong, for prevention Jiang Miao " day burning " damages withered, Jiang Nong must be above the Jiang Miao covering with plastic film supported and suspended one deck shading screen carry out daylight and block, increased the amount of labour and the production cost of proportion of crop planting thus.

(3) summary of the invention: at the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of printing opacity compound mulch film that shades, and is intended to reduce the amount of labour and the production cost of proportion of crop planting.

For achieving the above object, the shade technical scheme of compound mulch film of the utility model printing opacity is achieved in that and comprises rete; It is on a side surface of rete, is spacing and is connected with several composite beds that shades.

When implementing technique scheme, the shape of the described composite bed that shades is square, rectangle, parallelogram, circle or oval-shaped wherein a kind of.

The utility model is connected with several lamination layer structures that shades by be spacing on above-mentioned film surface, plastic mulching printing opacity and the double action of shading have been realized, the seedling that has guaranteed the mulch farming thing effectively is in process of growth, the effect of shading of both transparent heat insulating and soil moisturizing, the part when playing sunlight high strength irradiation mulch film again.Two kinds of different purposes of single mulch film, solved when daylight illumination is strong in the prior art need be above mulch film the deficiency of supported and suspended shading screen, reduced the labour intensity and the production cost of proportion of crop planting significantly.

(4) description of drawings:

Fig. 1 is the front view of first kind of embodiment of the utility model;

Fig. 2 be among Fig. 1 A-A to cross-sectional schematic;

Fig. 3 is the front view of second kind of embodiment of the utility model;

Fig. 4 is the front view of the third embodiment of the utility model.

(5) embodiment: Fig. 1--shown in Figure 4.This printing opacity compound mulch film that shades comprises the rete that is made of polythene material; On a side surface of described rete, be the spacing coating and be connected with several composite beds 1 that shades (Fig. 1, shown in Figure 2).According to the requirement of shading of different regions or the required printing opacity of different crops growth of seedling, the shape of the described composite bed 1 that shades can be the wherein a kind of of square (shown in Figure 1), rectangle (among the figure not shown in), parallelogram (shown in Figure 3), circular (shown in Figure 4) or oval (among the figure not shown in).During use, the utility model covers on the bracing frame of plantation crops seedling top, the transparent heat insulating and the soil moisturizing of overlay film canopy middle peasant crop seedling had both been played, the shade effect of part when having played time-division at noon daylight high strength irradiation mulch film again, two kinds of different purposes of single mulch film have guaranteed that effectively the crops seedling avoids the injury of " day burning ".

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characterictic that the process creative work just can be associated; can also make some modification or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.

Claims (2)

1. a printing opacity compound mulch film that shades comprises rete; It is characterized in that: on a side surface of described rete, be spacing and be connected with several composite beds that shades (1).

2. the printing opacity according to claim 1 compound mulch film that shades is characterized in that: the shape of the described composite bed that shades (1) is square, rectangle, parallelogram, circle or oval-shaped wherein a kind of.
