With the development of agricultural technology in our country, the technology of mulching film has also been developed relatively quickly. This technology will use a variety of products, such asWhite mulch, Silver gray mulch and so on. According to the experience of Qingzhou Luhong Plastic Co., Ltd. for many years, the temperature of the soil covered with plastic film is 2-4 degrees higher than that of the soil without plastic film, which can make the crops in the north germinate and grow earlier. At the same time, the mulching of soil moisture and weed growth control play a relatively large role.

Qingzhou Luhong Plastic Co., Ltd. will introduce a product commonly used in covering technology-white film, also called colorless plastic film. Its light transmittance is good. After covering, the ground temperature can be increased by 2 to 4°C, and the application range is relatively wide. Since the colorless plastic film is a high-pressure film, its thickness is only 0.03mm. It has the characteristics of good light transmission, high ground temperature and easy clay, which is suitable for northern regions. Mainly used for crops such as vegetables, melons and cotton.

But white mulch also has disadvantages, that is, it has a worse control effect on weed growth than black mulch. This is the problem of the characteristics of the plastic film. Because the albuginea has a good light transmittance and the weeds can undergo photosynthesis, the weeds grow fast.
