A course on the latest management techniques of grape sprouting period

Grape is a kind of fruit loved by many people. It is planted all over our country, and when planting grapes, we need to adjust the management methods of grapes according to the growth period of grapes. The appropriate management method is to ensure the normal growth of grapes, especially during the sprouting period. So how to manage the sprouting period of grapes? The following editor brings you the management technology of grape sprouting period, let's have a look!

1. Appropriate fertilization

In March every year, it is generally in the sprouting stage of grapes, which is also an important period for flower bud differentiation and new shoot growth of grapes. As a result, the demand for nutrients in grapes will also increase greatly. So the first thing we need to do well is to fertilize if the soil in the orchard is dry. Then it should be watered in time to ensure that the grapes sprout neatly. For the varieties with weak tree potential but better fruit setting, it is necessary to apply fertilizer in time. Adequate mature human feces and urine should be applied before grape sprouting, and the amount of urea should be kept at about 15% of the whole year.

2. Wipe the bud in time

After the vines are pruned in winter, the winter buds on the mother branches generally sprout about 70% and 80%. At this time, we should pay attention to the amount of buds, do not leave too many buds, if too much, it is easy to lead to waste of nutrition, tree potential becomes weak, affecting fruit setting. But the buds should not be too few, otherwise the branches and vines are easy to grow, resulting in serious flower and fruit drop. In general, a bud should be left on each fruiting mother branch at an interval of about 18 cm, keeping 3-4 new shoots, and then the excess should be erased from the base. When wiping buds, it is necessary to give priority to non-flowering panicle buds or weak buds, and one bud eye can retain a tip.

3. Fixed-tip binding vine

Then we have to do a good job of fixing and tying vines. First of all, for the retained new shoots, about 5 leaves should be kept on the flower ear before flowering. If there are no flowers, keep 8 leaves to pick the heart. After picking the heart, a large number of secondary shoots germinate, and one or two secondary shoots at the top of the tree can be retained, and they need to be picked repeatedly. Then wipe off the extra auxiliary tip, and then tie the vine according to the growth of the vine. Finally, it is necessary to remove the spike tip of about 1 stroke 5, and properly spray boron fertilizer and urea. About a week after flowering, fruit trees with more fruit should be thinned and bagged to protect them.

4. Other management

In the grape sprouting period, we should also pay attention to do a good job of ditch cleaning. Because there are more Rain Water in spring, whether it is a new orchard or an old orchard, it is necessary to do a good job in clearing ditches and drainage to avoid excessive water loss. Then appropriate ploughing and weeding should be done to improve soil permeability and concentrate nutrition. At the same time, when the grape withdraws about 4 new leaves, it is necessary to do a good job in disease prevention. Generally spray once a week or so, especially after the rain. According to the disease, appropriate chemicals are selected for control to ensure the normal growth of grapes.

The above is a brief introduction to the management technology of grape sprouting period. That's all for today's introduction. This article is for reference only. I hope it can help you all.
