"Returning Yang" fertilizer is also called fruit picking fertilizer. In some places, it is customary to apply fruit picking fertilizer one week before picking. However, in actual production, it is found that fertilizing before picking is not conducive to the storage of tangerine fruits. Pre-fruit fertilization is inconvenient due to the dense planting, and it is easy to cause mechanical damage to fruit trees and fruits. Therefore, the application of “returning the sun†fertilizer after harvesting should be carried out from late October to mid-November after harvesting. At this time, the ground temperature is higher, the fertility absorption is strong, and the injured roots heal quickly, which is beneficial to the safe overwintering of the tree. If the fertilization is too late, the roots injured by the low ground temperature will not be easy to heal, the ability to absorb fertilizer will be weakened, and the fertilizer will also be difficult to decompose, which often cannot meet the nutrient requirements for the growth of spring shoots and flowering and fruit the following year. After the fruit is picked, in a suitable application period, dig 4-6 radiating trenches 20 cm deep, 30 cm wide, and 80-100 cm long under the canopy, and apply 35-50 manure and urine fertilizer to each plant. Kg, add 0.1~0.3 kg of urea, and backfill the soil after application. In order to restore the tree vigor as soon as possible and improve the cold resistance, spray 0.3% urea plus 0.002% 2,4-D liquid fertilizer. Watering enough water while fertilizing, it can not only dilute the concentration of fertilizer solution, prevent root burning, but also help the root system to absorb quickly.
