With the increasing market demand for fruit quality, in addition to management, climate, geography and other factors, cultivation of high-quality apples is a very important factor in laying reflective film. The use of retroreflective coatings can double the original coloring degree. Can increase the brightness of the fruit, and the apple that lays a film is at least 0.15~0.2 Yuan more than the uncovered apple. When laying the film, according to the actual cut off a part of the useless branches (mainly winter cut the cut upright branches and thin branches), remove some shading of leaves, in order to increase the transparency, improve the role of reflective film. Choosing the right time, after 3~7 days in the apple picking bag, the effect is the best. The position of the film is about 80 cm to 1 meter from the trunk. Every little distance, use a small plastic bag to put a little earth pressure cover. Tear-off paper bags can also be loaded with soil. The main purpose is to prevent the reflective film from being blown by the wind.
But try to press on the edge of the reflective film in order to increase the reflective area. The quality of reflective films on the market is now uneven, and the quality of good film is very different. A good reflective film can be painted after two or three days. Poor quality reflective film can take seven to eight days or even longer, especially when it is cloudy or rainy. A film with poor quality can greatly reduce the effect or not work.
We hope that farmers' friends can choose reflective films with care. We must choose a reflective film of good quality, so as not to affect the quality of Apple.
