The matters needing attention in fertilizing after fruit setting and the management strategy are in place to achieve high yield.

It is now in the fruit-setting period of the vine, and it is also an important period for the management of the vine. How to fertilize the grapevine is related to the yield of the vine in the later stage. Here, small farmers will share with you some questions about the management of the fruit-setting period of the vine.

What kind of fertilizer do you need during the fruit setting period?

The main purpose of fruit setting period is to promote fruit expansion and reduce the occurrence of diseases. At this time, the fertilizers needed are nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, and should cooperate with spraying potassium dihydrogen phosphate to the leaves to promote fruit expansion and ripening.

Specifically, after entering the fruit-setting period, first of all, we need to pay attention to reasonable flower thinning and fruit thinning to avoid the impact on fruit growth in the later stage, reduce the incidence of diseases and improve fruit quality.

Nitrogen fertilizer was mainly used in the early stage of fertilization in the fruit setting stage of grapevines, which promoted the nutrition absorption and fruit growth of grape trees. About 30 kilograms of urea fertilizer can be spread per mu of vineyard. At the same time, attention should be paid to supplement phosphate fertilizer and potassium fertilizer to promote fruit expansion. You can choose calcium superphosphate and potassium sulfate, applying about 30 kilograms per mu. Pay attention to supplement calcium fertilizer. These fertilizers are usually used again every other month or so.

And spraying insecticides to reduce the occurrence of diseases. After spraying insecticide, the grapes can be wrapped in a bag to improve the quality of the grapes.

What is mentioned above is the fertilization method during the fruit-setting period of the grapevine, which needs to be changed slightly in the later stage of fruit-setting of the vine. In the early stage, the fruit is mainly expanded, but in the later stage, we need to consider the taste and color of the grape fruit. After all, only good quality grapes can be sold at a high price. At this time, the grape leaves can be sprayed with potassium dihydrogen phosphate solution to promote good fruit growth, and combined with urea and potassium sulfate fertilizer.

In addition, it is necessary to pay attention to the prevention and control of diseases and insect pests during the fruit setting period of grapes. Such as white rot, downy mildew, anthrax and other diseases. Usually apply more organic fertilizer, improve the light transmission and ventilation of the leaf surface, find diseased branches and diseases in time, deal with them in time, etc.
