Grape sprouting technology

Sprouting grapes in spring is a very important light, it is related to the future growth of grapes and hanging fruit, the correct sprouting can effectively increase the yield, but we should also pay attention to the operation methods, so as not to be counterproductive. Let's take a look at the sprouting techniques of grapes.

1. Sprouting effect

The winter bud of grape is a kind of mixed bud, which often contains multiple buds in one bud. When the same bud germinates, more than two buds of different sizes will grow. At this time, the buds will compete with each other for nutrients in the later stage, affecting the quality of the bud. In addition, there are some hidden buds, they do not have a fixed budding position, after budding often without inflorescence, without any effect. Grape is a plant with strong light demand, and it can grow normally only under the condition of good ventilation and permeability, so sprouting in spring can prevent the aimless growth of new shoots, enhance permeability and avoid aimless consumption of nutrients.

2. Sprouting time

The sprouting time of grapes is extremely important, and many people tend to think that it is carried out at the beginning of the bud, but in fact, grapes generally have to grow 4-5 leaves in order to see the breath, so it should be carried out according to the number and size of inflorescences. Generally, it is carried out when the length of the new shoot is about 10 cm, and all the buds should be wiped in a short time.

3. The method of wiping buds

Wiping buds are generally carried out on the main branches and lateral branches, three of the five adjacent buds growing on the main branches are erased, and only the buds at both ends are retained as fruit branches. If there were three bud holes and three buds on the short branch last year, the lower two should be erased, leaving only the top one as the fruiting branch. In the case of more buds, one bud can be left every 30 centimeters, and the rest can be erased to ensure that the buds have adequate vegetative growth and development.

4. Points for attention

When wiping buds, we should pay attention to the tree potential and soil power. Planting trees with poor soil strength and weak tree strength should leave fewer buds, on the contrary, strong soil power and strong tree strength can stay more. Secondly, when wiping buds, it is not suitable to break directly with your hands, which will cause larger wounds and is not easy to heal. You should choose sharp scissors to cut off directly from the base, and scissors should also be disinfected.
