The autumn base fertilizer should be 2~3 months ahead of the winter hedge base fertilizer, and should be carried out immediately after picking the fruit clearing. The basic fertilizer of autumn application should be based on organic fertilizer and supplemented by chemical fertilizer, so that the combination of soil improvement and support, delay and quick effect complement each other. Fertilizer application should pay attention to the proportion of nitrogen, phosphorus and potassium fertilizer. It is not advisable to apply too much quick-acting nitrogen fertilizer, otherwise it will easily cause winter shoots. At the same time, it is necessary to apply trace elements in a targeted manner. Adult fruit trees are applied with 60~80 kg of organic fertilizer, 150 g of urea, 3~4 kg of superphosphate or calcium magnesium phosphate, and 0.5 kg of potassium sulfate.

The fertilization method can be applied by ditch or by disc. When the ditch is applied, a circular, rectangular, curved and other fertilization ditch is formed at the position of the canopy drip line. The ditch depth is 40~50 cm, and the groove width should be determined according to the amount of fertilization, and the ditch bottom should be flat. After dripping, dry the fertilizer into the ditch and cover the soil immediately after the water is dry. Before fertilizing, the roots of the exposed grooves should be flattened along the ditch wall, and the cuts should be smooth to prevent the roots from being moldy and rotten. When fertilizing, the fertilizer should be applied layer by layer. The coarse fertilizer such as leaves and weeds should be placed on the bottom layer. The upper layer should be placed with organic fertilizer. Each layer of fertilizer should be covered with a layer of soil. Finally, the soil should be 25~30 cm above the ground. Due to the staggered distribution of the roots of the adult orchard soil, the disc method can be used, that is, the topsoil is opened along the plant spacing or row spacing on one side of the plant, and the shallower (8-10 cm) near the trunk when the soil is rammed, farther from the trunk. It should be deep (40~60cm), then apply dry fertilizer and cover the soil.
