Unreasonable pruning resulted in overt branches and vegetative branches of the apple tree after pruning, poor ventilation and light transmission in the crown, affecting the normal maturity of the fruit, and directly affecting fruit coloration.
Insufficient flowering and thinning of fruit results in excessive loading of the whole tree and excessive fruit retention. Due to uneven competition and distribution of nutrients, small fruits, partial fruits, malformed fruits and bumps are formed.
Inappropriate management of fertilizer and water in orchards The partial application of nitrogen fertilizers for many years in orchards can easily lead to soil compaction, making it difficult for trees to absorb trace elements such as calcium, potassium, zinc, and iron. In particular, during fruit enlargement and near maturity, when water is not applied in a drought, it will affect The normal growth and development, ripening, and coloring of fruits also tend to cause skin shrinkage and roughness.
Improperly bagging the bag before the application of the apple is in the young fruit period, at this time the fruit is very sensitive to drug stimulation, if the use of sulfur, arsenic, copper pesticides, fruit rust easily formed on the fruit surface.
Poor bag quality or premature bagging improper handling, easy to injure the young fruit hair, so that the rough fruit surface, too late the bacteria can easily invade the fruit, causing lesions or rotten fruit. In the case of bagging, care must be taken because of improper handling or artificial injury.
Calcium-deficient apple trees have a large demand for calcium, but due to the low mobility of calcium, the absorption is difficult, and the selectivity is time-efficient. Therefore, calcium deficiency is likely to form small cracks and rust spots in the fruit stems and pods.
Improper handling of the bag after picking leaves, reflective film, fruit transfer, resulting in uneven coloring of the fruit surface.
Weather affecting high temperatures, droughts, winds, rain, and frost damage will have an adverse effect on fruit coloring.
