Appropriate harvesting and storage of apples

The early and late harvest of apples directly affects the yield, quality and storage. If harvesting is too early, the fruit development is incomplete, the fruit is light, the appearance is poor in color, the sugar content is low, and the quality is poor; if the harvesting is too late, the pulp flies quickly and the disease resistance is low. Only suitable harvesting can achieve the best food quality, longest shelf life, and higher yields. 1. The suitable harvest period of apples is determined according to the maturity of the fruit. Mainly based on the following aspects: 1 Appearance traits including fruit size, shape, color, etc. have reached the intrinsic properties of the species. Seeds turn black and fruit powder matures. ? 2 internal indicators of fruit hardness is generally 5.4 ~ 6.8 kg / square centimeter, the earlier the maturity of low hardness, storage of fruit than slightly higher than the hardness of fresh; solids content of 12% to 15%, depending on the maturity of the species is delayed, solids High content. 3 starch content of fruit pulp mature fruit starch into sugar, starch content decreased. The iodine solution can be applied to the cross-section of the fruit. If 70% to 90% of the fruit is not stained, it indicates that it has matured. 4 During the fruit growth period, each species has a relatively stable number of days from flowering to maturity, generally 100 to 120 days for early maturing varieties, 125 to 150 days for medium maturing varieties, and 160 to 175 days for late maturing varieties. Because the accumulative temperature in different areas of the fruit growing period is different, the harvesting period will be different. It is best to harvest in different places within 10 days before and after the harvest period. 2. Picking operation precautions: 1 Promote picking fruit bags, picking fruit ladders, fruit boxes (baskets) and other harvesting tools. Cut nails and wear soft-soled shoes before picking. 2 When operating, hold the fruit with your hands, place your index finger against the end of the handle and gently lift it upwards. The fruit handle is separated from the fruit table and avoid hard pull. The light pick, light, light, and light should be used. in principle. 3 The order of picking is to pick the outer and lower parts of the crown first, then pick the inner part and the upper part. ? 4 should not be carried out before the rain, fog or dew dry before, should choose good weather fruit picking. 3. Post-harvest storage? 1 timely cooling after harvest, also known as pre-cooling. The apple harvesting season coincides with the autumn high temperature season, especially when the mid-maturing varieties are harvested, the average daily temperature is still around 25°C. The fruit not only has its own respiration heat released, but also holds a large amount of field heat, and the fruit temperature is higher than the temperature. The fruits after harvest must be cooled. Optional shade dry ventilation place in the open. Cover the straw curtain during the day, uncover it at night, and complete the pre-cooling within 1 to 2 days. In the process, prevent rain. 2 Storage can be selected according to local conditions. Such as trench storage, storage in crypts, cave storage, ventilation storage, mechanical cold storage, and advanced air-conditioned storage and other methods. The principle is to adapt to local conditions, simple and practical, small investment, easy management, and improve the preservation quality. Specific storage methods can refer to relevant information.
