First, scientific fertilization. Re-apply organic fertilizer, increase phosphorus and potassium fertilizer, apply appropriate nitrogen fertilizer in order to enhance tree vigor, which is the basis for improving fruit quality and promoting coloration.
Second, improve lighting.
1. Properly trimming and opening the light path. When winter cuts are done, "the big branches are bright and the branchlets are noisy", leaving less branches and leaving more twigs. Before the coloring of the apple, the upright branch, the shade branch, the thin branch of the inner branch, and the long branch on the periphery were clipped to improve the ventilation and light transmission conditions inside the crown, and to promote the coloring of the fruit in the interior and the middle.
2. Under the tree is a silver reflective film to improve the lighting condition in the lower part of the canopy and promote fruit coloring. A film can be used for 2 to 3 years.
3. Pick leaves to fruit. Remove the leaves that cover the fruit during the fruit coloring period, and gently turn the fruit so that the back yin is facing the sun. In 2 or 3 turns, do not rotate too much at a time, so as to avoid hurting the handle or turning off the fruit.
Third, spray coloring agent.
1. Spray "red apple". New Red Star Spray “Red Apple No. 2†and Red Fuji Spray “Red Apple No. 3†are sprayed 1000 times in the month before harvest or 500 times in the first half of harvest.
2. Spraying abt10# green plant growth regulators can promote coloration, increase apple weight, increase sugar content, and reduce pre-harvest fruit drop.
Fourth, fruit bagging. The fruit surface of the bagged bag is clean, smooth, non-polluting and colorful. The specific method is: set the bag after fruiting (spray a fungicide before bagging), go to the bag before coloring, if it is a double bag, go outside the bag first, interval 3 to 5 sunny days and then go to the inner bag. Can also set plastic film bags, the color is red, and no longer go bags, fruit picking can be with the fruit.
