In terms of technical methods and their application, we should be correct and reasonable, neither heavy nor heavy, just right, just right. Don't be hasty, sloppy and eager for quick success, only pay attention to quantity and ignore quality.
Trees widely used in production include natural fans with or without trunk and multiple main vines, ordinary fans with or without trunk and dragon trunk. Without the trunk, many main vines are naturally fan-shaped. This tree has no obvious trunk on the ground. With the decrease of plant spacing, the number of main vines decreases.

Although grapes can be planted in various soils (improved), loam and fine sand loam are the best. Although sandy soil has good air permeability, its ability of retaining fertilizer and water is poor. Loam is between sandy soil and clay.
It has strong water and fertilizer retention capacity, and most of them are very fertile. Grapes are easy to blossom and parthenocarpy when they grow vigorously, and have good fruit and high yield under high temperature and light conditions. There is less sunshine at low temperature, the result is not very good and the yield is low;
Pay attention to drainage at ordinary times and avoid exploratory tillage. In the early stage, there are few phenomena of virtual growth, flowing flowers and parthenocarpy, but it is easy to virtual growth in the later stage of development. Although the ear is large, the sugar content and meat quality are often not very good, so it is necessary to apply more high-carbon organic matter or add a little sand to improve it, and it is best to neutralize the acidic soil with appropriate amount of lime.
