采用标准地调查和标准株定位观察对人工菇木林杜英、桤木等树种进行了连续5年的年生长量调查和2年的物候期观察及年生长周期的测定。经调查测试结果表明，在相同环境条件下，各树种的物候与生长有关，叶芽萌动早的树种生长快年生长期长，而林木的年生长周期和幼林期的长短因不同而异，如桤木、银荆造林头1～2年生长很快，第2年就有部分植株开花进入性成熟，标志进入成年期，而马褂木、麻栎等树种造林后第5年，树高生长还呈直线上升，粗生长刚开始加快，表现出幼林期长。
Using standard survey and standard strain locating observation, the annual growth of 5-year-old tree species such as Du Ying and Alnus cremastogyne, and two-year phenological observation and annual growth cycle were studied. The investigation and test results show that under the same environmental conditions, the phenology of each species is related to growth. The early budding sprout grows fast in the long-term growth period, while the annual growth period and young-stand length of the forest tree vary from one species to another, In the first year or two years of planting silver shrubs, the plants grew rapidly in the first year or two. Some plants flowed into sexual maturity in the second year, which marked the beginning of adulthood. However, in the fifth year after the planting of species such as Liriodendron chinense and Quercus acutissima, Rise, coarse growth has just begun to accelerate, showing a long young forest.
