Key points of management of sapphire grape in different periods

Sapphire is a new grape variety which is different from ordinary grape in quality and appearance. Because of people's curiosity, it was welcomed by many people after it was listed on the market. As a result, more and more people grow sapphire grapes, and their planting area is naturally getting larger and larger. In the cultivation of sapphire grapes, the management method is very important, each period has different management points, the following editor will give you a brief introduction.

1. Bleeding period

When the soil temperature rises to about 7-8 degrees every spring, the roots of the grapes gradually recover and begin to absorb nutrients. The nutrients are then transported to the ground part of the plant to promote the sprouting of grape branches. However, because the vessel of the sapphire grape stem vine is thick and loose, when the sap activity is strong, if there is a wound on the plant, then the sap will flow out from the wound, this is the sapphire grape bleeding period. Therefore, in the bleeding period, we should strengthen management, do not allow trees to appear wounds, try not to do pruning work, do a good job of loosening the soil and weeding, and prevent injuries.

2. New shoot growth period

The growth period of new shoots is generally about 35 days when the bud eye of the vine grows to the early flowering stage. When the average daily temperature is above 10 degrees, the sapphire vines begin to sprout, and after about half a month, the new shoots grow faster and enter the full bloom. Because at this time, the organ parts of sapphire grapes are in a prosperous period, which is related to the key to the yield of the year. Therefore, we should do a good job in fertilization and control the proportion of nitrogen, phosphorus, potassium and other nutrients. In order to prevent excessive nutrition consumption, we also need to do a good job of fixing and removing buds, and reasonably adjust the load of grapevines.

3. Flowering period

The flowering period of sapphire grapes is relatively short, and the longest time from the first flower to Xie flower is only about half a month. When the temperature rises to about 25 degrees, it is the optimum temperature for sapphire grapes to bloom, and if the temperature is lower than 15 degrees, it will reduce the rate of flowering and fertilization. Therefore, in the flowering period, we should properly apply fulvic acid and other fertilizers to improve the rate of fertilization and fruit setting. And in the flowering period, we also have to do a good job of binding vines, removing tips and so on. To improve the permeability of the field and promote flowering, artificial pollination should be carried out for some flower ears with poor pollination.

4. Berry growing period

When the grape berry room begins to expand, it enters the berry growing period of the sapphire grape. It lasts until the berries change color and soften. During this period, the demand for nutrition of sapphire grapes is relatively large, so we should improve the proportion of nutrition, not only to improve the basic nutrition such as nitrogen, phosphorus and potassium, but also to supplement various trace elements such as calcium and boron in time. In addition, foliar fertilizer should be properly sprayed to enhance leaf photosynthesis, increase nutrient accumulation, promote fruit expansion and improve berry quality.

The above is a brief introduction to the key points of the management of sapphire grapes in each period. The management of sapphire grapes is very important, and the quality of management directly affects the output, so we must pay more attention to it. That's all for today's introduction.
