Black plastic mulch film is a black plastic film used for agricultural covering with polyethylene as the main raw material, adding antioxidant, ultraviolet absorber, black masterbatch, and produced by plastic film blowing machine.
Product advantages
1.Strong fertilizer preservation ability: The soil covered by black mulch film has small temperature change and is relatively stable, and the organic matter will also be in the normal cyclic static.
2.Good water retention ability: Our company's field experiment results show that the water content of 5 cm underground after the black mulch is covered by our company is 4-10% higher than that of the transparent film after two days or 35 days.
3.Prevention of adverse effects: The black mulch produced by our company has low light transmittance and less radiant heat transmittance, which can ensure that the temperature change of the covered soil is small.
4.Mobilizing fruit and vegetable yield: compared with transparent film, the soil temperature change of black mulch is less, especially for some root crops with low soil temperature demand, such as cowpea, Sishi bean, west orange persimmon, late watermelon, etc., whether the early per unit yield or the total yield of black mulch produced by our company can be higher than that of covering the head transparent film.
5. Prevent weeds: When the transparent film is covered, the weed hazard is a serious thing, and after the black film is covered, the ground weeds are difficult to develop due to insufficient light, so as to achieve the preventive effect.
The differences between black plastic mulch film and white plastic mulch film
1. The ground temperature difference of black plastic mulch film is small, the permeability of black plastic mulch film is better than that of white plastic mulch film, and the plants of black plastic mulch film are not easy to prematurely age, which can effectively inhibit the growth of weeds, and is suitable for crops with low ground temperature requirements. Especially in the summer.
2. black plastic mulch film light transmittance is low, weak thermal radiation, because it is almost opaque, weeds can not germinate and photosynthesis, so the effect of weeding is significant. However, the warming effect is not as good as the white plastic mulch film, and the summer daytime has a cooling effect. When used, it is spread on the ground, so that the crop is exposed outside the film, and it can also be spread between crop rows. black plastic mulch film is used more for common fruit tree seedlings.
3. White plastic mulch film features: white plastic mulch film has strong transparency, but the light transmittance is only 40%, which is not as good as black mulch for inhibiting weed growth. It is mainly used for tiling and covering, and can be used for planting all kinds of fruits and vegetables in early spring in the north.
