Correct use of colored agricultural film
In the past two years, with the rapid development of high-yield, high-efficiency, and high-quality agriculture in China, especially the rapid expansion of vegetable greenhouses, various colored agricultural films have been widely used in agricultural production. Appropriate use of colored plastic film can play a role in increasing production, increasing income, and preventing disease. If it is improperly applied, it will be counterproductive. The correct application methods of the nine kinds of colored agricultural film are described as follows: Black film weeds in severe plots or cultivated summer radish, cabbage, spinach, autumn cucumber, late tomato in high temperature season, and the black membrane is better. Purple membrane This membrane is mainly suitable for the cultivation of solanaceous and green leafy vegetables in greenhouses or plastic greenhouses in winter and spring, which can improve quality and increase yield. Yellow film According to the test, the celery and lettuce were covered with a yellow film. The growth of the plants was large. The convulsions were postponed and the beans grew robust. When they were covered with cucumbers, the flowering of the buds was promoted and the yield was increased by 1 to 1.5 times. The tea plants were covered, and the quality of the tea was superior and the yield was improved. . The practice of red membrane production proved that the rice seedlings cultivated under the red membrane are flourishing, sugar beet is high in sugar content, carrot roots grow longer, and leek leaves are broad and fleshy, the harvesting period is advanced, and the yield is increased. The blue film is mainly suitable for rice breeding, which is conducive to the cultivation of dwarf seedlings. It can also be used in vegetables, cotton, peanuts, strawberries, beans, eggplant, sweet peppers, tomatoes, melons and other vegetables and other economic crops. To control the role of weeds. The silver-gray film is mainly suitable for the cultivation of summer vegetables, melons, cotton and flue-cured tobacco. It has good functions of preventing disease, preventing aphids, whiteflies and improving quality. The silver reflective film is mainly used for greenhouse vegetable cultivation, and can be hung in the greenhouse to cultivate the north side of the loquat to improve the lighting conditions in the greenhouse. Silver Black Double-Sided Film The film is a composite of milk grey and black film. Covered with silver gray film on the film, black film under, with a variety of functions such as avoiding disease, preventing weeding and water retention. Mainly suitable for summer and autumn vegetables, melons and other disease-resistant heat cultivation. When the black-and-white double-color film is covered, white is on top and black is on the bottom, and it is mainly suitable for heat-resistant cultivation of vegetables and melons in summer and autumn. With a good effect of lowering the temperature, the water retention and weed control effects are also very good. The use of the film for ground cover cultivation of radish, cabbage, lettuce and other cool vegetables will grow well.
