If the base fertilizer is applied for the first time after planting, it can be opened outside the planting ditch: a groove 30 cm wide and 60 cm deep. When ditching, the topsoil and the raw soil are open. Before fertilizing, first fill a layer of topsoil (about 10 cm), then apply the base fertilizer and fill the topsoil. Then, the soil and fertilizer are stirred all over, and finally backfilled with raw soil to the ditch, and the remaining soil is used for watering. The second is the application. This method is commonly used in old vineyards. The basic fertilizer will be spread among the grape rows, and then ploughed. The advantage of this method is that it saves labor and time, and it has a wide range of fertilizers.
