A: In the late stage of fruit growth, a silver-gray reflective film is placed under the canopy to enhance the light reflection and promote coloration. Removing the shading leaves near the fruit and carefully changing the fruit 20 to 30 days before picking the fruit will help to increase the coloration of the red variety and improve the fruit quality. In addition, spraying fertilizers such as high-phosphorus and high-potassium liquid at the late stage of growth can also increase fruit coloration.
