Black and Silver Mulch Film

Black and Silver Mulch Film

The front of the product is silver and the back is black. When covering, the silver side is upward and the black side is downward, so that the original white and black mulching film can not only achieve the effect of heat preservation and humidification when the ground temperature is low in winter and spring, but also reflect sunlight in summer and autumn high-temperature seasons, reduce the ground temperature and promote the development of plant roots. The silver surface of the plastic film can reflect more than 80% sunlight. The reflection of light will make the back of the leaves of the lower part of the crop fully reflect the light, greatly reducing the incidence rate of the lower leaves of the plants. The most harmful insects such as 100% louse, aphids and other insects who love to eat on the back of the leaves are most afraid of Yin Baiguang, which will greatly reduce the incidence of such pests. The incidence of weeds under the film was almost zero when the reverse side was black and opaque. Because of its unique technology, plastic film can be recycled after crop harvest to avoid land pollution.
