Restore the tree situation after grape harvest.

After grape harvest, it is necessary to keep the grape leaves and prevent premature shedding, as an important work of management.

After grape harvest, the leaves still carry out photosynthesis and increase the accumulation of nutrients. Therefore, attention should be paid to the protection of grape leaves, except those with diseases and insect pests and withered leaves should be removed, other leaves should be retained as long as possible.

For the current year's branches that are still growing, we should gently pick the heart and promote the branches to mature.

In order to promote the recovery of tree potential, preserve leaves, prolong the time of photosynthesis and promote branch ripening, post-fruiting fertilizer should be applied, 15 kg compound fertilizer and 0. 5% urea per mu. 3% solution was used for 2 to 3 times of extra-root topdressing. The garden with exuberant trees can be applied less or not to prevent the new shoots from growing and consuming nutrients.
