Black And White Alternating Mulching Film

Black and white alternating mulching film is a kind of matching film with black film strip and white film strip, which adopts co-extrusion blow molding technology in the process of making film. It not only has the function of increasing temperature and preserving soil moisture, but also has the function of weeding and regulating ground temperature. At the same time, different growth environments under the white part and the black part are used to plant in different colors in different seasons, which can mediate the rhizosphere temperature and water environment requirements of different roots at different growth stages. 

Function by color:

consists of alternating black and white parts. The black part can effectively inhibit the growth of weeds, because weeds can not carry out photosynthesis in the dark environment; The white part can fully penetrate the sunlight, rapidly increase the ground temperature and promote the growth of crops.

Good thermal insulation and moisture retention:

it can reduce soil heat loss, keep soil temperature relatively stable, and reduce the impact of diurnal temperature difference on crops. At the same time, it can reduce the evaporation of soil water, maintain soil moisture, and provide suitable water conditions for crop growth.

High transparency:

the white area has good light transmission, which is conducive to direct sunlight in the soil, increasing soil temperature and promoting photosynthesis

Improve crop yield and quality:

Adjust the ground temperature, provide a suitable growth environment for crops, promote root development and plant growth, thereby improving crop yield and quality.

Inhibit weed growth:

reduce weeds and crops to compete for nutrients, water and sunlight, reduce the cost and labor intensity of weeding. Compared with ordinary transparent mulch, the part of black and white mulching film can better prevent weed growth and reduce the use of herbicides.

Easy to observe the growth of crops:

the white part can clearly see the emergence and growth of crops, which is easy to find diseases and pests, lack of seedlings and other problems in time, and take corresponding management measures.

 When laying film, please be careful to let the crop under the white part of the film, if the crop under the black part will affect the photosynthesis of the crop
