Answer: The pruning of mature fruit trees is for the purpose of "improving light, improving branch quality, and stabilizing high-quality production". The focus of pruning is to dredge batches of overgrown large auxiliary branches, large lateral branches, and large branches in batches. The large branches retained above the second floor extend outward, and the total branch volume accounts for less than 20% of the total branch volume of the whole tree, so as to facilitate the light in the inner cavity of the first layer. Depending on the strength of the tree canopy, gradually fall down and be happy, and control the tree height below 3.5 meters; if the canopy has been transferred, the outer densely packed branch group must be dredged or transformed into a small branch group to extend the short trunk length. , Slow the outside and promote the inside, or change the direction and angle of the main side branches by turning the main and changing the head, so that the top and bottom and left and right are staggered from each other, and the crown distance is maintained about 1 meter, in order to improve the group and individual lighting conditions.

Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.
