How to manage grapes during the budbreak stage? Latest technical methods tutorial

Grape is a fruit loved by many people. It is grown all over our country. When growing grapes, we need to adjust our management methods according to the grape's growth stage. Suitable management methods are those that ensure the normal growth of grapes, especially during the budbreak stage. So how should grapes be managed during the budbreak stage? Below, the editor brings you the management techniques for the grape budbreak stage. Let's take a look!

1. Appropriate fertilization

Every year in March, grapes are generally in the budbreak stage, and this is also an important period for grape flower bud differentiation and new shoot growth. Therefore, the grape's demand for nutrients also increases greatly. So the first thing we need to do well is fertilization. If the soil in the orchard is relatively dry, then water it in time to ensure uniform budbreak of the grapes. For varieties with weak tree vigor but relatively good fruit set, fertilize in time. Before grape budbreak, apply sufficient decomposed human feces and urine, together with an appropriate amount of urea, keeping the amount at about 15% of the whole year's total.

2. Timely bud removal

After winter pruning of the grapevine, generally about 70%-80% of the winter buds on the fruiting mother branches sprout. At this time, pay attention to the number of buds retained. Do not retain too many buds, because if there are too many, it easily leads to wasted nutrients, weakened tree vigor, and affected fruit set. But retaining too few buds is also not advisable, otherwise the branches and tendrils tend to grow excessively, causing serious flower and fruit drop. Generally, on each fruiting mother branch, retain one bud at intervals of about 18 cm, keep 3-4 new shoots, and then remove the excess from the base. When removing buds, focus on budless flower-cluster buds or weak buds, and keep one shoot per bud eye.

3. Shoot positioning and vine tying

Then we also need to do a good job of shoot positioning and vine tying. First, for the retained new shoots, before flowering, retain about 5 leaves above the flower cluster and pinch the tips. If there are no flowers, then retain 8 leaves and pinch the tips. After pinching, a large number of secondary shoots will sprout. Keep only about one to two secondary shoots at the top of the tree, and these also need to be repeatedly pinched. Then remove the excess secondary shoots, and do the vine tying work according to the growth of the branches and tendrils. Finally, remove about 1/5 of the tips of the flower clusters, and appropriately spray boron fertilizer and urea. About one week after flowering, for fruit trees with more fruit set, thin the fruit and bag them for protection.

4. Other management

During the grape budbreak stage, we should also pay attention to clearing the ditches. Because there is relatively more rain in spring, both newly built and old orchards should do a good job of clearing ditches and drainage to avoid waterlogging caused by excess water. Then also carry out appropriate intertillage and weeding to improve soil aeration and concentrate nutrients. At the same time, when grapes send out about 4 new leaves, do a good job of disease prevention. Generally, spray once about every week, and especially strengthen spraying after rain. Choose suitable pesticides for control according to the disease, so as to ensure the normal growth of grapes.

The above is a brief introduction to the management techniques for the grape budbreak stage. That is all for today's introduction. This article is for reference only and I hope it can help everyone!
