Black greenhouse filmLow transmittance, only less than 10%, covering grassy areas, weeds cannot get the necessary sunlight after germination and death occurs, weed control effect is stable and reliable, and saves labor; black film decreases temperature slowly, good water retention performance, in high temperature season covering cool vegetables, less heat transfer, water evaporation, which can promote growth. If using shade net, the cooling effect is more obvious.
Black plastic film was the best choice for planting summer radish, Chinese cabbage, Autumn Cucumber and late tomato in plots with serious weeds or high season temperature.
Green greenhouse film
Using green film, green light increased and visible light decreased, thus reducing the photosynthesis of weeds under plastic film, restraining their growth, thus playing a role in weed control; green greenhouse film on soil humidification is not as good as transparent film, but stronger than black film, beneficial to the growth of the above-ground part of crops, yield increase effect is significant.
It is widely used with strawberries, melons, tomatoes, eggplants, peppers and other vegetables, generally can increase the yield of tomatoes and eggplants by 22% and 49%, respectively, but also to make the eggplant luster and good coloring.
Blue greenhouse film
Under the condition of weak light, the transmittance is higher than that of transparent film, but under the condition of strong light, it is lower than that of transparent film, so the heat preservation performance is good, and the temperature in the film is generally higher 2℃ to 3℃ than that of transparent film.
It can be used in vegetables, strawberries, peanuts and other crops, and has good inhibition effect on the black spot pathogen of cruciferous vegetables.
Silver gray film
It can reflect ultraviolet rays, repel aphids and whitefly, alleviate crop viral diseases, repel yellow leaping beetle, cucumber and weevil, and inhibit the growth of weeds and good water retention effect.
It is suitable for disease prevention and heat resistant cultivation in spring or summer and autumn, such as Solanaceae, cucurbits, vegetables and tobacco.
Silver reflective film
It has the function of reflecting light, heat insulation and reducing ground temperature. It can be used as the side wall of the greenhouse and to improve the light intensity between plant rows and fruit trees and promote coloring.
It can be used for ground covering of tomatoes, grapes, cherries and apples in greenhouse.
Black and white mulch filmIt can enhance the reflected light, reduce the ground temperature, and keep water and weed killing effect well.
It is mainly used for heat-resistant cultivation of vegetables and melons in summer and autumn. For example, it is better for insect prevention, rainproof, windproof and shade protection when combined with small arch shed.
Silver Black film
It has multiple functions of reflecting light, avoiding aphids, killing grass, and suitable crops are the same as black and white double-sided film.
