Picking time for bag collection is different according to the type of fruit bag and apple variety. 1 The use of single-layer bags for yellow-green varieties can be picked at the time of harvest. 2 For red varieties using single-layer bags, about 30 days before harvesting, the bags should be torn to be umbrella-shaped and covered on the fruit to prevent direct sunlight. After 7 to 10 days, the bags should be removed to prevent sunburn. Accelerate coloring. 3 For red varieties, double bags are used. Before 30 to 35 days of fruit harvesting, outer bags are picked first. After the outer bags are removed, the inner bags are removed after 4 to 5 sunny days. 4 The appropriate time for bag picking in a day is from 9 a.m. to 11 p.m., and from 3 p.m. to 5 p.m. in the morning, picking up the paper bags on the south side. Be sure to avoid the strongest time of sunlight at noon to avoid sunburn. Picking time is too early or too late to reach the expected effect of bagging, premature bag picking, dark fruit surface color, poor finish; late picking bags, fruit surface color, storage fading. When picking the double bag, use the left hand to hold the fruit, the right hand will straighten the “V†shaped wire plate, unfasten the bag mouth, and then use your left hand to pinch the bag and the right hand gently pulls the outer bag down to keep the inner layer. The bag, so that the inner bag is attached to the fruit by the support of the fruit. Generally picking the inner bag after picking up the outer bag for 5 to 7 days (need to be deducted on cloudy days) should be performed at 10 to 14 o'clock. The occurrence of sunburn is not caused by the direct sunlight, but is determined by the surface temperature of the skin and the temperature of the atmosphere. Therefore, as long as no large temperature difference occurs, sunburn can be avoided. In addition, in case of rainy weather, the time for picking up the inner bag should be delayed so as to avoid the formation of chlorophyll on the surface of the consequential skin. When picking a single-layer bag, first open the bottom of the bag to ventilate it or tear the paper bag into strips, and then remove it after a few days. Attention when picking the bag 1. Pay attention to irrigation. Before filling the bag, pay attention to the irrigation of water to reduce the occurrence of fruit cracking and fruit loss and apple shrinkage. 2 pay attention to picking time. The correct apple picking time is the key to producing high quality fruit. 1 If the bag is taken too early, the apple will be exposed for a long time, resulting in a rough fruit surface, high pathogen infection rate, and the significance of losing the bagging; 2 If the bag is picked too late, the fruit coloring is poor, the coloring is uneven, the hardness is reduced, and the sugar content is reduced. reduce. 3. Pay attention to pruning the dead branches near the fruit. When picking the bag, be careful to prune the dead branches that are likely to cause fruit damage and prevent the fruit from being injured. 4. Note the weather when picking bags. Picking bags is best done in cloudy or cloudy weather, avoiding rainy days.
