The football field in foreign countries is always special green. Green is neatly green. In fact, these colors are not natural, but the colors that are produced using lawn dyeing techniques. However, after hearing this explanation, people would question the environmental protection and safety of the lawn. Turf coloring is actually a landscape reconstruction method that began in the United States in the 1950s. In the early days it was mainly to facilitate the greening of the filming scene.
Currently, there are two major types of turf colorants used in the market: natural colorants and synthetic colorants. The former main coloring material is mainly mineral powder or plant extract color, and the latter is some synthetic dyes such as indigo blue. At the same time both contain thickeners, dispersants, and adhesion tests. These coloring components can adhere to the surface of plants and the soil, maintaining a period of time ranging from 60 to 120 days.
With the increase in the demand for landscape reconstruction, non-oily lawn colorants that are basically harmless to plants and the environment have been developed for use in lawn green areas that are directly in contact with the human body, such as golf courses, football fields, leisure lawns, and home lawns. The landscape reconstruction can be used to extend the turf green period, repair diseased patches and improve the visual effects of the landscape, and the cost is lower than the strengthening of conservation and increase of nutrition. From the viewpoint of the composition of the colorant, the coloring components used are basically low toxicity and non-toxic to the human body and the environment. After spraying the colorant, it can prevent turf overgrowth to a certain extent. It has also been reported that as the lawn is generally treated with coloration in autumn and winter, the sprayed colorant can form a protective film on the plant surface to reduce water loss and chlorophyll decomposition. If the colorant is added with trace elements or fertilizer components, it also has a certain nutritional effect on artificial turf.
It can be seen that the dyed lawn does not have much harm to the human body and the environment. Compared with the unevenly colored lawns at some of the domestic stadiums, we naturally prefer to see green grass lawns. Watching the ball is not just looking at the ball, but sometimes it is a whole visual.
