The correct use of colored agricultural film

    Scientific use of colored agricultural film can achieve good results in increasing production and preventing disease. If improperly applied, it is often counterproductive and the consequences cannot be estimated. The scientific use methods of several colored agricultural films are introduced below for reference by farmers.

 

    First, the black film. The cultivation of summer radish, cabbage, spinach, autumn cucumber and late tomato in severe weeds or high temperature seasons is better.

 

    Second, the purple film. The membrane is mainly applied to the cultivation of solanaceous fruits and green leafy vegetables in greenhouses or plastic greenhouses in winter and spring, which can improve quality and increase yield.

 

    Third, the blue film. It is mainly suitable for rice breeding, which is good for cultivating short-stem seedlings. It can also be used for vegetables, cotton, peanuts, strawberries, kidney beans, eggplant, sweet peppers, tomatoes, melons and other economic crops. The role of grass.

 

    Fourth, the yellow film. According to the experiment, the celery and lettuce are covered with a yellow film, the plants grow tall, the bolting is delayed, and the beans grow strong; covering the cucumber can promote the flowering of the buds and increase the yield by 1 to 1.5 times.

 

    Five, red film. The production practice proves that the sugar beet cultivated under the red film has high sugar content; the root of the carrot is longer; the leaf of the amaranth is wide and fleshy, the harvest period is advanced, and the yield is increased.

 

    Sixth, green agricultural film. The green film can reduce visible light and increase green light, thus reducing the photosynthesis of weeds under the film, inhibiting growth, and thus killing grass; the green film has less humidification effect on the soil than the transparent film, but stronger than the black film. It is beneficial to the growth of the aerial parts of the crops, and the yield increase effect is remarkable. It is mostly used in vegetables such as strawberries, melons, tomatoes, eggplants, and peppers.

 

    Seven, silver gray film. It is mainly used for cultivation of summer and autumn vegetables, melons, cotton and flue-cured tobacco, and has good effects of preventing disease, preventing mites and whitefly and improving quality.

 

    Eight, silver reflective film. It is mainly used for greenhouse vegetable cultivation. It can be hung in the greenhouse to cultivate the north side of the greenhouse to improve the lighting conditions in the greenhouse.

 

    Nine, silver and black double-sided film. The film is a composite of milk gray and black film. When the cover is covered, the silver-gray film is on the top and the black film is on the bottom. It has various functions such as avoiding disease prevention and weeding and water retention. It is mainly used for disease prevention and heat-resistant cultivation of summer and autumn vegetables and melons.

 

    Ten, black and white two-color film. When covered, the white is on the top and the black is on the bottom. It is mainly suitable for the heat-resistant cultivation of summer and autumn vegetables and melons. It has a good effect of lowering the ground temperature, and the water retention and weeding effects are also very good. The film is used for ground cover cultivation of radish, cabbage, lettuce and other cool vegetables, which can grow well in summer.
