How to scientifically use colored plastic film

In order to improve the quality of different vegetables, it is possible to use colored plastic films of different colors. Since various colored films absorb and reflect different spectra, the effects on vegetable growth, weeds, pests and ground temperature are also different.

For example, green membranes are mostly used for planting vegetables such as strawberries, kidney beans, eggplants, sweet peppers, tomatoes, melons, etc., which can better prevent weeds. Under the red agricultural film, the roots of the carrot grow larger, the leaves of the amaranth are thick and thick, the harvest period is advanced, and the yield is increased. The purple film is mainly suitable for cultivation of solanaceous fruits and green leafy vegetables in greenhouses or plastic greenhouses in winter and spring, which can improve quality and increase yield. Covering the cucumber with a yellow film can promote the flowering of the bud, increase the yield, cover the celery and lettuce, the plant grows tall, and the bolting is delayed.

Therefore, when planting different vegetarian dishes, the corresponding colored plastic film should be selected to make the products more distinctive and the benefits are better. In addition to the use of colored plastic film in agriculture, it will be used in other places, mainly to decorate the appearance.
