Autumn application of grape basal fertilizer can increase the accumulation of nutrients in the tree body and avoid soil drought caused by fertilization, so that the basal fertilizer can exert its fertilizer effect timely. Fertilization time. Early and mid-maturing grapes can be applied after harvesting, late-maturing grapes can be applied before harvesting, and late at the end of October. Base fertilizer method. Apply a ditch along the fixed line to open a groove 30 cm wide and 60 cm deep. The topsoil and raw soil are opened. Before fertilizing, backfill a layer of top soil (about 10 cm), apply the basal fertilizer, and fill the topsoil. Then, the soil and the fertilizer are stirred again, and finally, the raw soil is backfilled into the ditch level, and the remaining soil is used as a rake to facilitate watering. Basal fertilizers must be applied to rot, especially chicken manure, and should avoid damaging the roots. After fertilization, it is necessary to pour once and permeate the soil, producing 2,000-3,000 kilograms of vineyards per acre. Basal fertilizer can be applied to 4000-5000 kilograms. Shelf fertilization, along the direction of vine growth year by year from the inside to open the trench fertilization. Basal fertilizer can not always be applied in one place, and it is easy to cause the growth of roots to be blocked and rot to die.
