Note 1: Buy paper bag, no love low price bags. Generally poor quality film bags and paper bags though cheap, but a considerable number of manufacturers are undocumented, non-standard product specifications, quality tests, a result difficult to improve the

quality of apple. General value-added film bags about 40% of Apple, but Apple's general value-added paper bag 1-2 times. Therefore, the proposed conditions of the majority of growers in the economy, subject to the selection of buy paper bag in good quality as well. If economic conditions do not allow, can be the selection of quality film bag.

Note 2: Bagging of Calcium to make up. Buy paper bag for apples in particular sets of paper bag of apples, due to the long in a dark, damp micro-environment, the transpiration capacity greatly reduced, poor capacity to absorb calcium. If bagging had not calcium, it is easy because of calcium deficiency caused by a number of physiological diseases, such as bitter pit, water pox spot disease and heart disease and so on. In the fruit area, some farmers do not attach importance to calcium, some only a calcium supplement, on a hurry to bagging; so production of red spot disease of too much fruit bagging. In general, bagging should be sprayed 2-3 times before the high-quality calcium.

Note 3: Bagging pest thoroughly before sterilization. Number of apple fruit surface many black spots, plant protection experts to study that is mainly single-ended sp pink, round leaf blight and Kang's Powder Scale and other hazards caused. Many farmers lack of awareness, prevention and control in place, spray the medicine just before bagging, and no use of quality pesticides, causing black spot disease is very serious. General requirements before bagging high-quality pesticide spraying 2-3 times, each time interval of 7-10 days, together with calcium.

Note 4: Bagging the time of earlier inappropriate. Apple young fruit cell division period is the heyday require adequate light. If bagging too early, in the dark environment is not conducive to cell division in young fruit enlargement. Some farmers more in 20-30 days after flower fruit bag sets will be completed, the time of the earlier, so Apple height small. Based on years of experience, sets of paper bags suitable period 35-40 days after anthesis. But bagging time should not be too late, too late to cover rough surfaces under the apple.

Note 5: To guard against wind attack. Typhoon great influence on the apple, it is recommended when the mountain farmers in bagging two points: First, the low-lying sheltered orchards should be multiple sets of paper bags, windy mountain orchards should be multiple sets of film bag; second windward side of fruit per plant and the upper canopy should be more sets of membrane bags, the leeward side of the crown and lower crown and the bore should be multiple sets of paper.

Note 6: After bagging Mo relax pest and disease control. Many mistakenly believe that buying apple fruit bagging, the pest is not easy to damage the fruit, and to relax the control of pests. Some bagged only a pesticide spray, and some one does not spray, resulting in early leaf disease and outbreaks of spider mites and other pests and diseases, many of Fuji tree leaves in late August in the rate reached 40%, worms from stomata into the pocket of the bag is also a lot of damage fruit. In fact, the apple bagging leaves and fruit after the insurance is still important and must not relax the control of the pest, should a grasp in the end.

Note 7:After buy paper bag, do not remove paper bag earlier. In order to promote Apple's early morning city coloring, some farmers premature lifting of a paper bag. According to my investigation, all cooked apple in a paper bag to lift early premature, because at that time was high season, although the color back, but the high temperature caused a serious sunburn. The paper lifted early and late-maturing apple tree coloring too long, and mostly dark red color, good gloss. Judging whether early or late in the cooked apple apple will directly affect the premature lifting of a paper bag apple appearance and efficiency. In general, early in the morning, cooked apples colored to early city, and merchants can be a good first contact and then lift the bag to determine the time, late-maturing apple harvest should normally be about 25 days before the lifting of a paper bag. On the contrary, the time can not lift the bag too late, too late for the poor apple coloring.
