1、 Why not

1. Variety problem: it may be a variety problem. The planted varieties belong to female flower varieties, which cannot be pollinated and fertilized, and naturally will not bear fruit. Common varieties include black chicken heart, flower leaf white chicken heart, Anji Wen, etc

2. Improper pruning: during the management period, the plant grows vigorously, but if it is not pruned for a long time, the branches will grow in vain, the internal branches and leaves will not see light, and the maturity of bud eyes is poor, so that flower buds cannot form and fruit will not be set

3. If the weather is not good enough for continuous pollination, or if the weather is not good enough for continuous pollination, it will lead to poor nutrition

2、 What if you don't know the result

Since you don't know the reason for the result, you should pay attention in advance. Prune in time at the growth stage to cut off the thin, diseased and repeated branches, so as to make the interior better ventilated and transparent. Proper fertilization should be applied before flowering, mainly by applying high phosphorus fertilizer to promote flower bud differentiation. In addition, help pollination. When flowering, you can wear gloves and touch the male flower buds, so that the pollen will stick to the gloves, and then touch the female flower buds, which can help pollination and improve the fruit setting rate
