After the grapes bear fruit, it is necessary to prune the buds first to thin out the branches and leaves that grow too densely to improve the light transmittance between the plants. and ventilation to avoid poor growth. At the same time, the branches of the grapevine that have grown too long should be shortened to prevent them from wasting nutrients.

2. Pruning of fixed stems

The pruning of fixed stems should be divided into two times. The first time should be carried out in time after the inflorescence appears on the new stems, in order to distinguish the The fruiting branches and vegetative branches will not be confused. The second time is carried out about 5-7 days before flowering. Of course, it can also be combined with the new topping work, and the two are carried out alternately and at the same time.

Introduction to grapevine maintenance methods:

1. Reasonable pruning

Pruning of grapevines is very important and needs to be pruned every spring and autumn. In spring, the main purpose is to prune the long branches and shorten them. After harvesting fruits in autumn, all dead branches, yellow leaves, overcrowded branches, and diseased and insect-infested branches should be cut off.

2. Reasonable fertilization

Grape itself is a plant that likes fertilizer very much. When planting, it is necessary to add enough base fertilizer to the soil to ensure that the soil is fertile. Decomposed manure and compost can be used as base fertilizer. During the peak growth season, a lot of nutrients are consumed, so top dressing is required two or three times. Compound fertilizer or decomposed organic fertilizer can be used for top dressing.

3. Management during the flowering and fruiting period

During the flowering and fruiting period of grapes, flowers and fruits must be thinned in time, which will be determined according to the growth strength of the branches. If it is a strong fruit branch, keep 1-2 inflorescences on each top, keep 2 inflorescences on medium and strong branches, and do not need to keep inflorescences on the tips of weak branches. After fruit setting, the fruits must be thinned in time to remove diseased, deformed, and weak fruits.
