Poor illumination Many orchards are densely planted, the scenery conditions are deteriorated, and the fruit is not well colored because it does not see light or see too much light. This is a major cause of poor apple coloration. The difference in fruit coloration of the inner and lower skirt branches is caused by this reason. For this situation, it is necessary to carry out the renovation of the dense planting and closing garden. Unbalanced nutrient supply Some fruit farmers do not know much about this. Fertilization has blindness. It has not been done according to the technical requirements of balanced fertilization of soil testing formula. For a long time, it has been heavy inorganic fertilizer, light nitrogen, no phosphorus or less potassium fertilizer, and abuse of trace amounts. Fertilizer, the nutrients required for the growth and development of the fruit can not be balanced, which affects the yield and quality of the fruit. Insufficient water Adequate water supply is an important ecological factor that promotes apple coloration. During the apple coloring period, in case of drought and no rain, it should be irrigated in time to increase the humidity of the orchard and promote the coloration of the fruit. At the same time, the good orchard humidity can also adjust the temperature difference between the day and night of the orchard, thus promoting coloring. In the coloring period, if it is brighter in the open air, it is better. If there is no exposure or less open, the coloring is slower and worse. Load too high Excessive load is not only easy to cause years of age, but the quality of the fruit will also decline. As the fruits are crowded, the light is blocked and the coloration is not comprehensive. The correct method is a reasonable load. The easier method to grasp is the method of spacing and leaving fruit, that is, the large fruit leaves 2 apples at a pitch of 20 to 25 cm, and the small fruit leaves 1 apple at a pitch of 15 to 20 cm. Generally, the output of mu is controlled at 3,000 to 4,000 kg. Did not pick leaves, turn fruit After the bag is removed, the leaves and shading leaves should be removed in time to make the fruit shine. The positive color of the fruit is better to change the fruit in time, and the fruit is padded to make the fruit surface even and complete. The laying of the reflective film can make the color of the inner and lower skirts of the dense garden complete, so as to promote the coloration of the fruit.
