In the process of agricultural planting, the mulch film is indispensable. The mulch film can effectively control pests and weeds, and can also warm, protect and promote precocity, and ensure the growth of crops. The common film on the market has black and white, so what are they? What is the difference? Which one is better? Let's take a look at it below. First, the benefits of black and white film 1, can increase the soil temperature of the plough layer, which is conducive to the germination and emergence of crops, especially spring-sown crops and autumn-sown crops, the temperature is relatively low, the effect is more obvious. 2, the film has a strong water retention capacity, can effectively prevent rapid evaporation of water, especially in dry land, after watering is conducive to preservation. 3. After the mulch film is laid, the weeds can not be exposed to sunlight and breathing, which can effectively prevent their growth and even kill weeds. 4. Because of the heat preservation effect, the soil temperature of the plough layer can be increased, which leads to the accelerated growth of some crops and the advancement of the growth period to promote the maturity of the crop. Second, what is the difference between black and white mulch film? 1, light transmittance The black mulch film has a light transmittance lower than that of the white mulch film, that is to say, when the temperature is high, the temperature of the ploughed soil can be lowered, so that it has a high temperature effect, so the black mulch film is suitable for summer crops. The white mulch is highly transparent, but the light transmittance is only 40%, which is inferior to the black mulch for inhibiting weed growth. It is mainly used for tiling, and all kinds of fruits and vegetables can be used in the early spring in the north. 2, ground temperature difference The temperature difference of the ground film temperature of the black film is small, the permeability of the black film is better than that of the white film, and the plant of the black film is not easy to prematurely decay, which can effectively inhibit the growth of weeds and is suitable for crops with low ground temperature requirements. Summary: Whether it is black mulch or white mulch, they all have their own characteristics, but not all crops are suitable for mulch during crop planting, so you can pay attention to crop habits before use, and when summer crops are warm. It is recommended to use black mulch. The above is about the introduction of black and white mulch. Do you have anything to add?
