Recently, it is the key period for the late-ripening apple to lay the reflective film. Properly laying the reflective film can quickly promote fruit coloration and improve fruit quality. Choose a good quality reflective film At present, the quality of reflective film products on the market is uneven. The general quality is better. The double-sided composite film of polypropylene, polyester aluminum foil and polyethylene has strong toughness, high reflectivity and strong anti-oxidation ability. If the quality is poor, the recycled material is added in the production process, and the pulling force is weak, the brittleness is large, the cracking is easy, and the light reflecting rate is low. When you choose, not only must you look at the price, you must also pay attention to the quality of the reflective film. It is best to choose a pure double-sided composite film. Supporting technology must keep up In order to improve the rate of full red fruit, the reflective film should be combined with management techniques such as picking leaves, turning fruits, pulling branches, and trimming autumn to enhance the use effect of the reflective film, thereby producing high-quality high-quality fruit. Problems to be aware of When laying the reflective film, it should be high inside and outside, so that the rainwater can flow to the line to prevent the film area from affecting the reflective effect. Many fruit farmers have saved their work and directly placed the reflective film on the ground between the orchards. After the rain, the membrane area was severe and the reflective effect was poor. It is not advisable to use soil for the film to prevent the reflective film from being stained and affecting the reflective effect. The film surface should not be pulled too tightly to prevent the reflective film from shrinking and rupturing when the temperature is lowered.
