How to Prevent Grapevine Excessive Vegetative Growth? A Detailed Guide to Practical Control Methods
Everyone has surely eaten grapes. There are many grape varieties, and they are all very popular in the market. The cultivation range of various grape varieties in our country is also very large, and growing grapes has basically become a way to get rich. However, when many people grow grapes, they do not properly control the phenomenon of excessive vegetative growth of grape branches, resulting in a serious decline in grape yield later on. So how should grape branch excessive vegetative growth be controlled? Let's take a look together below!
1. Shoot control
Properly control the branches on the grapevine and reduce the number of shoots. When deciding which shoots to keep and which to remove, you should keep the new shoots that can bear fruit and remove the old shoots that cannot bear fruit. For controlling the number of shoots, we should follow the principle of “keep the new and remove the old” to ensure that the number of shoots on the tree is within what it can bear. Only by timely removing some branches that cannot flower and bear fruit can excessive vegetative growth be effectively prevented. This can not only strengthen the growth of fruit-bearing shoots and prevent the loss of water and nutrients, but also ensure fruit yield and the quality of fruit enlargement.
2. Water and fertilizer
Water and fertilizer are the most important management tasks in cultivation, and having a reasonable watering and fertilizing method is the key to ensuring high yield and high efficiency. The watering method depends on your own conditions. Most use drip irrigation or sprinkler irrigation. These two methods can not only save a certain amount of water, but also allow the orchard to receive water evenly. They can also control the amount of water used and effectively prevent excessive water from making branches grow too quickly and causing excessive vegetative growth. Fertilization should also be determined according to the actual growth situation, and must not be too little or too much, otherwise it will also cause great harm to the growth of the plant.
3. Bud removal
Bud removal is the best way to control excessive vegetative growth of branches, because many excessively growing branches grow from these new buds. Usually, grapes begin to grow new buds in winter, but sometimes the formation of new buds is not good for the growth of the plant. Therefore, we should promptly remove excess new buds, especially the new buds growing at the base of the main trunk, because the growth ability of new buds in these parts is not strong. They not only cannot grow into new shoots that can flower and bear fruit normally, but also consume more nutrients, doing only harm and no good to grape growth. These new buds should be removed in time.
4. Shoot tying
Grapes are a vining fruit, and they have very many branches, with side branches of all kinds. For some newly grown branches, shoot tying work should be carried out, because if the growth position of the new shoots is not fixed, the new shoots will grow randomly without direction. Therefore, when the new shoots grow to a certain extent, we should fix and tie the new shoots in one position. This can not only control the excessive vegetative growth of branches and prevent the branches from swaying everywhere in windy weather, but also effectively enhance the ventilation and light penetration in the orchard, prevent too many leaves from causing the lower part of the plant to receive no light and reducing the plant's photosynthesis, and reduce the accumulation of nutrients and sugars in the fruit tree.
The above are several methods for preventing excessive vegetative growth in grapevines. Preventing excessive vegetative growth in grapevines is very important. Excessive vegetative branches of grapes cannot flower and bear fruit, but they need a large amount of nutrients and water. Therefore, reasonably controlling excessive vegetative branches can not only effectively prevent them from competing with fruit-bearing branches for nutrients, but also reduce fertilizer consumption and improve fertilizer conversion rate.
