Grape planting management technology;

Fertilizers mainly include phosphorus, potassium, moderate boron and other fertilizers, and organic fertilizers such as river mud can also be used.

2. Insect control. Similar pests only occur for one generation (June-August) in the north, and may only occur for two generations in the south. The main pest species are moth larvae, with green body and yellow antennae, commonly known as bean worms or bean Dan; Grape longicorn larva with purple, gray or dark green stripes.

Step 3 trim. From 1 1 month, the grape leaves began to turn yellow and fall. In winter, grape growers in cold areas must cover their roots with soil to prevent the vines from freezing to death.

In order to slow down the aging of grapevines and control the grape yield, it is necessary to prune them from winter to March every year, and the lignified grapevines must be pruned into the required shape according to different pruning systems. Vines that die in the middle of the year must also be replanted in winter.
