First, the benefits of autumn basal fertilizer can increase the accumulation of nutrients in the tree body. The second is to facilitate root healing and new roots. The third is to avoid soil drought caused by fertilization. The fourth is to make basal fertilizer effective in time. Second, Shiji fertilizer time In general, early and mid-maturing grapes can be applied after harvesting, late-maturing grapes can be applied before harvesting, the latest in the early October is finished as well. Third, the method of basal fertilization First, the ditch is applied. Usually along the planting line ditch. If the base fertilizer is applied for the first time after planting, it can be opened outward along the planting furrow: 30 cm wide and 60 cm deep furrows. When the ditch is opened, the topsoil and raw soil are opened. Before fertilizing, backfill a layer (about 10 cm) of topsoil, and then apply basal fertilizer and fill the topsoil. Then, the soil and the fertilizer are mixed together, and finally the raw soil is backfilled into the ditch, and the remaining soil is used as a hoe to facilitate watering. The second is appendage. This method is commonly used in old vineyards. The basic idea is to spread the base fertilizer between the rows of grapes and then plough them. The advantage of this method is that it saves time and labor and saves a lot of money. The disadvantage is that the fertilization is too shallow and the amount of fertilizer needs to be increased. Fourth, a few issues that should be noted are: First, basal fertilizer must be cooked, especially chicken manure. The second is to avoid hurting the thick roots. The third is based on the fertilization of the soil in the garden, and the elements that are lacking in the berry, especially some trace elements. Fourth, it must be poured once after fertilization. The fifth is to determine the amount of fertilizer. In general, a vineyard with a yield of 2,000 to 3,000 kilograms per kilogram can be applied to a base fertilizer of 4,000 to 5,000 kilograms, and a maximum of 10,000 to 15,000 kilograms can be applied. Sixth, the scaffolding is used for fertilizing. It is necessary to fertilize the vines in the direction of vine growth year by year. Seventh, basal fat can not always be applied in one place, and it is easy to cause the growth of roots to be impeded and rot to die.
