Apple fruit surface is clean and has a high trick

Fruit bagging. Fruit bagging is one of the best and most effective technical measures to improve the finish of apple fruit. Fruit bagging can make the peel smooth, delicate, bright color, reduce rust spots, and the fruit is small and small, thus improving the appearance quality of the fruit.

Control the amount and proportion of nitrogen fertilizer. The amount of nitrogen fertilizer is too much, the bagging fruit is chlorotic, the fruit surface is dull and dull, the red variety is slow and light; on the contrary, the nitrogen fertilizer is moderate, the skin color is light, the color is bright, the red variety is more vivid, and the fruit rust is changed. light.

The fruit grows freely. The fruit is free to sag and grow, not close to branches, stems, leaves and fruits, which can effectively avoid branch grinding, leaf grinding, water rust, striate and pests.

Rational use of pesticides and foliar fertilizers. If the pesticide or foliar fertilizer is used improperly or at a low concentration, it will often stimulate the fruit surface and make the fruit surface rough, and even cause phytotoxicity, affecting the smoothness and fruit traits of the fruit surface. One month before harvest, the orchard should stop spraying Bordeaux or concentrated lime emulsion, and switch to non-residue and residue-free fungicides, such as Dasheng M-45, Nongkang 120, and polymycin. The apple flowering period is 800 times liquid, the bud stage, the young fruit stage, the fruit expansion period and the 500-600 times liquid before spraying, and the young fruit is sprayed with amino acid compound micro-fertilizer 400 times before the harvest. These micro-fertilizers are sprayed 3 to 5 times a year to thicken the waxy layer of the fruit surface.

Spray fruit surface protectant. Spraying 500~800 times high fat film or 200 times paraffin wax emulsion can reduce fruit surface rust or peel crack, which has obvious effect on improving the appearance quality of apple fruit.
