The latest summer black grape field management

Xiahei grape is a high-quality grape variety, which has the advantages of strong disease resistance, high yield, early ripening time and high storage. Now there is a very large planting area in our country. After the market demand of summer black grape becomes larger, the demand for yield is also higher and higher. If you want to produce, it is very important to do a good job in field management. So the editor brings you the field management technology of Xiahei grape today. Let's have a look!

1. Water and fertilizer management

At the time of the establishment of the garden, we should apply enough farm manure, and fertilize once a year from now on, and control the amount according to the planting area. After the seedlings grow about 8 leaves, you can start to topdressing, about once every half a month. Nitrogen fertilizer is the main fertilizer in the early stage, and phosphorus and potassium fertilizer is mainly applied in the later stage, until the top dressing is stopped in September. If you encounter the rainy season when planting, you must do a good job of drainage, dig ditches, and prevent stagnant water retting roots. However, we should also pay attention to the replenishment of water in the dry season. The amount of water and fertilizer is guaranteed to be within the demand range of summer black grapes.

2. Fruit bagging

Fruit bagging is a very important fruit protection measure when growing fruit. So growing grapes is no exception, reasonable bagging work can effectively control diseases and insect pests, reduce pollution and so on. It is of great help to the yield and quality of summer black grape. When bagging, we should pay attention to the selection of bagging, bagging to ensure strong permeability and good drainage capacity. If the bagging is too closed, it can easily lead to fruit rot if it produces stagnant water. Then it is necessary to master the bagging time and bagging methods to ensure the yield and improve the planting efficiency.

3. Fruit enlargement

Fruit expansion treatment is also a very important management work for planting summer black grape. If the fruit is not enlarged, the fruit of Xiahei grape is small, and its commercial value will be affected. The expansion of the fruit is usually carried out about half a month after the flower falls behind. Gibberellin is the main expansion agent, and the object of spraying is fruit ear. Then spray again after half a month or so. Or gibberellin can be dipped in the ear when the berries grow to the size of soybeans.

4. Pest control

The pest control of Xiahei grape is also very important. First of all, we need to do a good job in the prevention and control of black pox, downy mildew and other diseases, especially in the first year, when the seedlings grow 3 leaves, spray fungicides every 9 days or so for disinfection. The choice of fungicides should ensure that at least two kinds of fungicides should be used in rotation to prevent the bacteria from producing resistance and lose the effect of disease resistance. Finally, we should often observe its growth, when there is an abnormal situation, we should find out the cause in time, and then make corresponding measures.

The above is a brief introduction to the field management of Xiahi grape. Field management is very important, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
