Causes of irregular sprouting of grape and its solutions

As the temperature gradually picks up, many plants begin to sprout. For grape growers, the sooner the grapes sprout, the sooner they can be put on the market. However, grape sprouting and irregular sowing is also a grape encountered by many growers, which not only takes time and effort to manage, but also leads to different ripening time of grapes, affecting the time to market of grapes and reducing economic benefits. So what is the reason for the irregular sprouting of grapes? How to solve the problem? Let's take a look.

First, the reasons for irregular germination

1. Lack of nutrition in the tree.

In order to pursue high yield, many growers lead to excessive consumption of tree nutrition and reduction of stored nutrients, so it affects the sprouting of the coming year. In addition, last year, the management was not in place after harvest, and the control of diseases and insect pests failed, which led to the early defoliation of grapes, the weakening of photosynthesis, the accumulation of nutrients and sowing, affecting the sprouting.

2. Improper pruning

The advantage of the top of the grape is strong, and it is farthest from the root, and its buds will sprout limitedly. If the pruning of the middle and long shoots leaves too many buds, the tip buds of the branches will begin to germinate first, and the later the germination time will be later, so it will cause irregular sprouting.

3. Lack of water

In grape sprouting, if there is enough water, it germinates earlier, and the germination rate is also relatively early, but if the soil is dry and short of water, it germinates later and the germination rate is relatively low. Failure to drain in time during the rainy season last autumn will lead to flourishing branches, insufficient accumulation of nutrients, and irregular sprouting.

4. Temperature

At the low temperature last year, if the cold-proof and anti-freezing measures were not in place, the persistent low temperature would cause slight freezing damage to the grape branches, and the poor transport of nutrients in spring would affect the sprouting and flowering. In addition, the low temperature would also affect the absorption of the roots, thus affecting the sprouting.

II. Solution measures

1. Apply base fertilizer

After grape harvest, base fertilizer should be applied in combination with clear garden in autumn, mainly organic fertilizer and farm manure, which can not only help grapes survive the winter, but also provide nutrients for plants and promote sprouting in the coming year.

2. Pruning and irrigation in time

The drained branches retracted in time, and the strong branches before and after uneven sprouting were retracted to the position of good buds and good branches, mainly to restore the tree potential. After the ground temperature rises, irrigate in time to ensure sufficient water, loosen the soil in time after watering to avoid soil consolidation, irrigation should not be too much, and keep the soil water content at 65%.

3. Fertilization

After the plant sprouting, we can promote its germination neatly by fertilization, mainly nitrogen fertilizer in the early stage and phosphorus and potassium fertilizer in the later stage. In addition, it can also improve the spraying of foliar fertilizer and promote the growth and maturity of new shoots.
