The latest how to improve the fruit setting rate of grapes

The prospect of grape planting is very good, but planting grapes is not simple. Grapes are a very fragile fruit. If you don't control the surrounding environment well, it will have a big impact on its yield. such as temperature, nutrition and moisture. Grape caused serious flower and fruit drop phenomenon, fruit set rate decreased. Therefore, how to improve the fruit setting rate of grapes is the problem that many farmers want to solve most. So, how to improve the fruit setting rate of grapes? Let's take a look at it together with Xiaobian below!

1. Prevent overgrowth

Many friends in the planting process of excessive growth of the branches did not pay attention to, let it continue to grow. As everyone knows, if a grape shoot grows too strong, it will affect the flowering rate of grapes. Grape growth should not be too strong, because too strong words will require a lot of nutrients, will compete for nutrients in the lower branches of the grape, so that grape development is poor. The ability of the newly grown branches to bear fruit in the second year will also decrease, so it is necessary to cut off the strong branches appropriately, leaving a small number of secondary shoots and increasing the area of leaves. However, it is also necessary to pay attention to the branches that grow too weak, and leave more secondary shoots to germinate and strengthen growth.

2. Reasonable fruit retention

When planting, most people think that the more fruit the better, so there is no reasonable thinning of fruit trees. This will not only not increase the yield of fruit, but also lead to poor quality of grapes and reduce the tree vigor of fruit trees. The poor development of fruit trees reduces the pollination rate of flower buds in the second year, and the accumulation of nutrients in branches in plants decreases, affecting the flowering and fruiting rate, resulting in flower and fruit drop. Therefore, we must carry out reasonable fruit retention, control quantity, ensure quality, and reduce the phenomenon of flower and fruit drop.

3. Ensure nutrition

Ensuring sufficient nutrients for grape growth is the key factor to enhance grape growth and improve fruit setting rate. After harvest, the orchard should be fully applied with base fertilizer, and the application amount should reach at least half of the fertilizer required for one year. Topdressing should be done at least three times a year, with the first application of appropriate nitrogen fertilizer before germination. In the fruit expansion period when the second topdressing, fertilizer can be decomposed farm manure, the last time in the fruit coloring, mainly with some trace elements, pay attention to the application of nitrogen fertilizer.

4. Prevention and control of diseases

Diseases and insect pests are also one of the main reasons for grape flower and fruit drop, so if you want to improve the fruit setting rate of grapes, you should also prevent the occurrence of diseases and insect pests. Grape diseases and insect pests and downy mildew, leafhopper, etc., in the annual harvest after the orchard should be timely comprehensive disinfection, residual sick branches, affected fruit concentrated for cleaning. Pay attention to stay away from orchards, and then low orchards should also be regularly cultivated, disinfected, cleared of germ eggs in orchards, reduced pathogens, and reduced morbidity.

The above is the way to improve the fruit setting rate when planting grapes, mainly some management problems in the planting process. Planting grapes can not be careless, must be careful and patient, to ensure the growth and development of grapes, so that grapes can bear fruit well. We can't keep fruit blindly in order to improve yield, so we should keep fruit reasonably, otherwise it will backfire.
