What to do about wampee fruit drop and fruit cracking? Please advise.
During the fruiting period of wampee, the main tasks are to protect the fruit, prevent fruit drop and fruit cracking, and promote fruit enlargement. Because there is a lot of rain and highly changeable weather from March to June, conditions are very unfavorable for wampee fruit growth, and orchards lacking management will show fruit cracking and fruit drop. The main methods to prevent fruit drop and fruit cracking are as follows:
① Fertilize to protect the fruit. Wampee is relatively sensitive to waterlogging; when the root system is soaked in water, it easily causes the leaves to turn yellow and, in severe cases, to fall. On sunny days, spread an appropriate amount of compound fertilizer within the tree canopy, or spray foliar fertilizer, to increase the tree's nutrient reserves.
② After sunny weather, spray pesticide to prevent the occurrence of anthracnose.
③ Thin the fruit. To ensure the fruit clusters are neat and the fruits are uniform in size, the small fruits from late flowers should be thinned out. For fruit clusters bearing too much fruit, part of the fruit can also be thinned out, which can reduce fruit cracking and fruit drop later on.
④ Fertilizing before harvest helps the tree recover and promotes the growth of autumn shoots. The wampee root system is relatively weak and is often affected by high temperature and drought weather. In orchards lacking fertilizer and water management, fewer autumn shoots are produced, which affects nutrient accumulation and affects flowering and fruiting the following year. Therefore, the number of autumn shoots and the quality of autumn shoots have a great impact on the annual yield.
⑤ Bagging. Because pests and diseases are more numerous after weather changes, in order to reduce pesticide spraying and improve fruit quality, bagging can be carried out during the fruit enlargement period. Before bagging, first thin the fruit, then spray pesticide to prevent pests and diseases, and finally bag the fruit.
