为探索减轻苹果幼树连作障碍的有效措施,在山东牟平、招远(2处)、栖霞、蒙阳共5处重茬果园定植苹果幼苗,结合综合防治技术体系进行管理,记录施入有机物料活化发酵液后连作苹果幼树的生理指标变化。结果表明,活化发酵液处理重茬土壤的树体生长势明显增强,中枝数量、短枝数量、枝粗、株高、地径、新梢长、叶绿素含量平均 In order to explore the effective measures to reduce cropping obstacles in apple trees, apple seedlings were planted in 5 orchards in Muping, Zhaoyuan (2 places), Qixia and Mengyang in Shandong Province, and integrated with comprehensive prevention and control technology system to record the activation of organic materials Changes of Physiological Index of Young Apple Trees after Fermented Broth. The results showed that the growth potential of the soil with activated carbon bricks was significantly increased, the number of middle branches, the number of short branches, branch diameter, plant height, diameter, shoot length and chlorophyll content were average
