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

Two nethike embranes

Technical field

The utility model belongs to agricultural production device technique field, is a kind of keeping the sun off and the nethike embrane of rainwater.

Background technology

The growing environment of ginseng needs the low light level and drizzle, generally grows in the sylvan life of mountain shady spot.At present, the artificial planting ginseng does not then have fit closely natural environment, need to build the rainproof guard of shading on the ground in ginseng, and its mode is the dark net that fishing net shaped is adopted on the upper strata, and in order to shading, lower floor adopts plastic film in order to keep off the rain, and consists of the rainproof hood for protecting rider of shading.And the process of growth of ginseng needs drizzle to moisten, and plastic film all blocks heavy rain and drizzle, is unfavorable for Ginseng Growth, and in addition, the plastic film windage is large, meets strong wind and dark net and plastic film together can be blown away.

Summary of the invention

The technical problems to be solved in the utility model provides a kind ofly can block high light, and can stop heavy rain, see through less than two thoroughly nethike embranes.

The scheme of the utility model technical solution problem is to adopt warp, one-level parallel and secondary parallel to consist of two thoroughly nethike embranes, warp, one-level parallel and secondary parallel are the sheet line, one-level parallel and secondary parallel are zigzag and are fixed on the warp, and adjacent one-level parallel and secondary parallel overlap each other.During use two thoroughly nethike embranes are built above ginseng ground, can effectively be blocked high light, and can stop heavy rain, see through light rain.Fell the same day when raining heavyly, rain spatters is on two nethike embranes, and most of rainwater flows away from two nethike embranes, and small part sees through nethike embrane and is the misty rain shape with falling into ginseng.

For shading saturating rain better effects if, be 0.14-0.18cm through line width, thickness is 0.02-0.03cm.

For shading saturating rain better effects if, the parallel width is 0.2-0.24cm, and thickness is 0.03-0.04cm.

For shading saturating rain better effects if, adjacent is 0.8-2. 4cm through linear distance.

For shading saturating rain better effects if, adjacent one-level parallel and secondary parallel overlap each other, and lap is half of parallel width.

Warp and parallel can adopt the low-density polyethylene material wire drawing to make, and color can be the dark colors such as black, blueness.

The utility model can block high light effectively, light transmittance 45%-55%, stop heavy rain, build undergrowth environment, and avoid being blown off by strong wind, utilize photosynthesis to make the volume increase of ginseng and other underground crop, synergy, be specially adapted to the ginseng planting, also can be used for other plant cultivation and animal-breeding.
