The black mulch has a small temperature difference, and the air permeability of the black mulch is better than that of the white mulch. The plants of the black mulch are not prone to premature aging, and the temperature of the black mulch is high at night.
The characteristics of the black mulch: The light transmittance of the black mulch is only 1% to 3%, and the heat radiation is only 30% to 40%. Because it hardly transmits light, weeds cannot germinate and photosynthesize, so the weeding effect is remarkable. Under sunlight, the black mulch will increase its temperature quickly and have high humidity, but less heat is transferred to the soil, so it is not as effective as a transparent film, and it also has a cooling effect during the summer. When in use, it is spread on the ground so that the crops are exposed out of the film, and it can also be laid flat between rows of crops.
Characteristics of white mulch: The thermal radiation rate of white mulch is 80% to 90%, which is close to transparent mulch, and the light transmittance is only 40%, which has a certain inhibitory effect on weeds. It is mainly used for tiled mulching, which can better solve the problem of serious weed damage in transparent mulching
