What to pay attention to in the field management of summer black grapes
Summer black grapes are a high-quality grape variety, with strong disease resistance, high yield, early maturity, and good storage. Now, there is a large planting area in China. With the increasing market demand for summer black grapes, the demand for yield is also increasing. To obtain yield, good field management is very important. Therefore, the editor has brought you the field management techniques for summer black grapes. Let's take a look!
Water and Fertilizer Management
When establishing a garden, we should apply enough farm manure, and fertilize once a year afterward, controlling the amount of fertilizer according to the planting area. When the seedlings grow about 8 leaves, they can start top-dressing, about once every half month. In the early stage, nitrogen fertilizer is mainly used, and in the later stage, phosphorus and potassium fertilizers are mainly used, with top-dressing stopped in September. In case of rainy season, good drainage must be ensured, and ditches should be dug to prevent waterlogging and root rot. However, water supplementing should also be noted in dry seasons. The amount of water and fertilizer should be within the demand range of summer black grapes.
Fruit Bagging
Fruit bagging is an important measure to protect fruits during the fruit planting process. Therefore, it is no exception for grape planting. Reasonable bagging can effectively control diseases and pests and reduce pollution, which is of great help to the yield and quality of summer black grapes. Attention should be paid to the selection of bags when bagging. The bags should ensure strong permeability and good drainage. If the bags are too dense, the accumulation of moisture can easily lead to fruit rot, so it is necessary to master the timing and method of bagging to ensure yield and improve planting efficiency.
Fruit Expansion
Fruit expansion is also a very important management task in the cultivation of summer black grapes. If the fruit does not expand, the volume of the summer black grape fruit is small, and its commercial value will also decrease. Fruit expansion usually occurs about half a month after the flowers wither. Gibberellin is the main expansion agent, and the spray target is the fruit cluster. Spray again after about half a month. Or you can dip the fruit clusters in gibberellin when the berries are the size of soybeans.
Disease and Pest Control
The prevention and control of diseases and pests in summer black grapes are also very important. First of all, it is necessary to prevent and control diseases such as black spot and downy mildew, especially in the first year, when the seedlings grow three leaves, it is necessary to spray a fungicide for disinfection every 9 days or so. At least two fungicides should be selected for rotation to prevent the pathogen from developing resistance and losing its effect. Finally, it is necessary to observe its growth condition frequently, and when abnormal conditions occur, find out the reasons in time and then formulate corresponding measures.
The above is a brief introduction to the field management of summer black grapes. On-site management is very important, so we must pay attention to it. That's all for today's introduction, this article is for reference only, and I hope it helps you!
