Four points for pre-winter management in apple orchards
Before winter, Shi Jianfei Han Mingyu told reporters that the first step of pre-winter management was after fruit harvesting. After the fruit is harvested, basal fertiliser should be applied immediately to the orchard without basal fertilization because the temperature is still high. The basal fertilization is not only conducive to root absorption and utilization, but also conducive to the restoration of root regeneration, and thus to the development and flowering of the second year tree body. The results play a safeguard role. Fertilization can be applied by ring groove method. In the canopy projection, trenches with a depth of about 40 cm and a width of about 40 cm can be dug, and then a layer of agricultural fertilizer can be buried.
