In recent years, various colored agricultural films have become widely used in farming practices. When used correctly, these films can boost crop yields, improve income, and reduce disease occurrence. However, improper use may lead to negative outcomes. Therefore, it is essential to apply colored agricultural films properly based on the specific needs of the crops.
Red film is particularly effective for rice seedlings, helping them grow vigorously. It also enhances sugar content in sugar beets, promotes longer root growth in carrots, and increases the size and yield of leeks.
Blue film is ideal for rice seedlings, promoting the development of compact and strong seedlings. It is also beneficial for vegetables like tomatoes, eggplants, peppers, as well as cotton, peanuts, and strawberries, by suppressing weed growth.
Black film is best suited for areas with heavy weed infestations or during hot seasons, such as when growing summer radishes, Chinese cabbage, spinach, autumn cucumbers, and late tomatoes.
Purple film is commonly used in greenhouses or plastic tunnels during winter and spring for growing solanaceous crops and leafy vegetables. It helps improve quality and increase yields.
Yellow film has shown positive results in enhancing plant growth. For example, celery and lettuce grown under yellow film tend to be taller, while beans develop more robustly. It also promotes flowering in cucumbers, increasing yield by 1 to 1.5 times. Tea plants covered with yellow film produce higher quality tea.
Silver reflective film is mainly used in greenhouses, especially on the northern side, to enhance light conditions and improve plant growth.
Silver-gray film is suitable for summer crops like melons, cotton, and tobacco. It helps prevent diseases, control pests such as aphids and whiteflies, and improves overall crop quality.
Silver-black double-sided film combines a silver-gray top layer with a black bottom layer. It offers multiple benefits, including disease prevention, weed suppression, and water retention. It is ideal for summer and autumn crops that require heat-resistant cultivation.
Black-and-white double-color film has a white surface facing up and a black surface down. It is excellent for heat-resistant vegetable and melon cultivation during hot seasons. It effectively cools the soil, retains moisture, and controls weeds. It is also useful for growing cool-season crops like radishes, cabbages, and lettuce in summer, allowing them to thrive under harsh conditions.
