When the fruit is produced, the branches should be pruned to ensure that there are five or six fruits on each branch. The top bud should be removed to save nutrients and promote nutrition to be provided to the fruit, so as to improve the output rate of the first grade fruit.
After fruit harvesting, the branches should be cut off from the base, leaving only two or three sections, so that the new fruiting branches can germinate. Three or four sections are left on the side vine to ensure that the side vine can grow smoothly in the later stage. In addition, at this time, the sick and weak branches, residual branches and overdense branches shall be cut off. If you have branches that are fast growing to the ground, cut them from a place 20-30cm away from the ground, which is more conducive to ventilation.
In winter, all the fruits are harvested. At this time, it is necessary to cut them again and save a lot of nutrients, so as to ensure that the multi-level branches are fully extracted and promote the increase of the number of buds and fruits in the later stage. In addition, at the end of March in spring, long branches and disease and insect branches should be cut off to prepare for the increase of production.
If it is hot before flowering and bearing fruit, and water is not timely, flower buds will not grow without water, and will turn yellow and fall off later. It is also possible that the flower bud can't grow in the low temperature environment during its growth, and the concentration of fertilizer applied at this time is too high, and its resistance is not strong, and this kind of phenomenon will occur.
