Picking the leaves, on the basis of reasonable shaping and trimming, improving the conditions of ventilation and light transmission in the crown, in the fruit coloring period, the leaves that block the fruit receiving light can be removed. However, the degree of leaf picking should not be too heavy, so as not to affect the differentiation and development of flower buds. Laying a reflective film and laying a reflective film under the crown of the tree for 10 to 15 days before harvesting, increasing the light reflection under the canopy and promoting fruit coloring. If the fruit is colored too late, consider removing the top film to improve the light and promote coloration. When the young fruit has a diameter of 5-10mm, it is necessary to spray a bag-free film and strong fruit timing to protect the fruit surface, broaden the path of the plant catheter, increase the absorption and absorption of cherries, and reduce the incidence of fruit drop, cracked fruit and deformed fruit. Spray the second bag-free film at intervals of 7-10 days, and then spray it for 30 times at intervals of 30 days to enhance the effect and cultivate all-weather open-air cherries. Although the color is not good, the taste is better than bagging. .
