CN202738548U - Double-penetration screen film - Google Patents

Abstract

The utility model discloses a double-penetration screen film and belongs to the technical field of agricultural production devices. The double-penetration screen film is formed by warp threads, primary weft threads and secondary weft threads, wherein the warp threads, the primary weft threads and the secondary weft threads are sheet-like threads; the primary weft threads and the secondary weft threads are zigzag fixed on the warp threads; and the adjacent primary weft threads and secondary weft threads are overlapped. During the use, the double-penetration screen film is constructed above the ginseng lands and is capable of effectively shielding the strong lights, resisting heavy rain and penetrating light rain. In heavy rain, raindrops fall on the double-penetration screen film, most of the rainwater flows from the double-penetration screen film and a small part of the rainwater falls into the ginseng lands through the screen film like mist. With the light transmittance of 45-55%, the double-penetration screen film is especially suitable for the planting of ginseng and also can be applied to the cultivation of other plants and the breeding of animals.

Description

double transparent membrane

technical field

The utility model belongs to the technical field of agricultural production devices, and relates to an omentum for blocking sunlight and rain. the

Background technique

The growth environment of ginseng requires low light and drizzle, and it generally grows under the forest in the shade of the mountain. At present, artificial planting of ginseng does not have a very suitable natural environment. It is necessary to build a shading and rainproof net cover on the ginseng ground. Blackout and rainproof canopy. The growth process of ginseng needs drizzle to moisten, and the plastic film will cover the heavy rain and drizzle, which is not conducive to the growth of ginseng. In addition, the plastic film has a large wind resistance, and the dark net and the plastic film can be blown away in strong winds. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a double-permeable omentum that can block strong light, block heavy rain, and pass through less than 100 mm. the

The solution of the utility model to solve the technical problem is to use the warp, the first-level weft and the second-level weft to form a double-transparent mesh. Fixed on the warp, the adjacent first-level weft and second-level weft overlap each other. When in use, the double-permeable omentum is built above the ginseng ground, which can effectively block strong light, and can block heavy rain and pass through light rain. When it rains heavily that day, the raindrops hit the double-permeable membrane, most of the rainwater flows away from the double-permeable membrane, and a small part of it falls into the ginseng ground in the form of rain and mist through the membrane. the

In order to have a better effect of shading and rain penetration, the warp width is 0.14-0.18cm, and the thickness is 0.02-0.03cm. the

In order to have a better effect of shading and rain penetration, the weft width is 0.2-0.24cm, and the thickness is 0.03-0.04cm. the

Better effect for shading and rain penetration, the distance between adjacent meridians is 0.8-2.4cm. the

In order to have a better effect of shading and rain penetration, the adjacent first-level weft and second-level weft overlap each other, and the overlapping part is half of the width of the weft. the

The warp and weft can be made of low-density polyethylene wire drawing, and the color can be black, blue and other dark colors. the

The utility model can effectively block strong light, the light transmittance is 45%-55%, block heavy rain, create an under-forest environment, and avoid being blown away by strong winds, and use photosynthesis to increase the yield and efficiency of ginseng and other underground crops, especially It is suitable for ginseng planting, and can also be used for other plant cultivation and animal breeding. the

Detailed ways

Example 1, the utility model is made of warp 1, first-level weft 2 and second-level weft 3, warp 1, first-level weft 2 and second-level weft 3 are sheet-like lines, and warp 1 has a width of 0.14cm and a thickness of 0.03cm , the width of the weft is 0.24cm, the thickness is 0.03cm, the distance between adjacent warp 1 is 0.8cm, the first-level weft 2 and the second-level weft 3 are fixed on the warp in a zigzag pattern, and the adjacent first-level weft 2 and second-level weft 3 overlapping each other, the overlapping part is half of the weft width. the

Example 2, other features are the same as Example 1, the width of warp 1 is 0.18cm, the thickness is 0.02cm, the width of weft is 0.2cm, the thickness is 0.04cm, and the distance between adjacent meridians is 2.4cm. the

Example 3, other features are the same as Example 1, the width of warp 1 is 0.16cm, the thickness is 0.025cm, the width of weft is 0.22cm, the thickness is 0.035cm, and the distance between adjacent meridians is 1.6cm. the
