Embodiment Construction
[0030] Below in conjunction with accompanying drawing, the present invention will be further described:
[0031] Such as figure 1 , a special mulch film for smoking under the film, including a mulch body 1, and a single black strip 2 with low light transmittance is longitudinally arranged on the mulch body 1 along the length direction, and the light transmittance of the black strip 2 is 0 to 60%. , other parts of the film body 1 are white. The width b of the film body 1 is 90-120cm, and the thickness is 0.004-0.08mm. The main material is polyethylene (PE), polyvinyl chloride (PV), polypropylene (PP) or polystyrene resin (PS). The width a of the black strip 2 is 5-40cm, and the distance between the longitudinal centerline 4 of the black strip 2 and the longitudinal centerline 3 of the film body 1 is 0cm, that is, the two overlap. The longitudinal direction is the length direction of the film, and the transverse direction is the width direction of the film.

Abstract
The invention discloses a special mulching film for tobaccos under film, belonging to the field of agricultural products and mainly solving the following problems that the common mulching films have high light transmittance and high temperature under film, so on the one hand, the tobacco seedlings can be burnt due to strong light or high temperature, and on the other hand, the high temperature under film causes moisture evaporation, causes the humidity not to be easily maintained and is not beneficial to tobacco seedling growth. The mulching film comprises a mulching film body, wherein a single or a plurality of black stripes with low light transmittance are longitudinally arranged on the mulching film body along the length direction; the light transmittance of the black stripes is 0-60%; and a plurality of through holes are also longitudinally arranged on the mulching film along the length direction and can be arranged in a single row, in a wavy manner or in double rows. The mulching film can prevent the tobacco seedlings from being burnt due to strong light or high temperature, simultaneously has the function of preserving heat and moisture and is beneficial to tobacco seedling growth.
Description
technical field [0001] The invention relates to an agricultural plastic film, in particular to a plastic film specially used for tobacco under the film. Background technique [0002] After tobacco is infected with viral diseases, the yield decreases and the quality deteriorates. Aphid-borne viral diseases have become one of the main factors restricting the development of tobacco production. At present, there is no pesticide with good curative effect on viral diseases in the world, and the fundamental way to prevent and control viral diseases is to control aphids. However, due to the large number of aphid hosts and the limitation of the agricultural environment, simply relying on the use of chemical agents on tobacco leaves to prevent aphids often has a weak effect. [0003] Some tobacco leaf producing countries in the world have studied different aphid avoidance measures and achieved remarkable results. Since 2000, my country has carried out a variety of aphid control meas...
