| 摘 要： | 采用Logistic曲线对柠条锦鸡儿、小叶锦鸡儿不同种源的苗高与地径生长进行拟合,并估测了速生期的2个拐点及其长度。结果表明:高、径生长均符合"S"型曲线,年生长可划分为生长初期、速生期、硬化期3个时期;直径生长速生期起始时间或早或迟于高生长,而结束时间晚于高生长;速生期的高、径生长速率均表现为N-3>X-2>N-2>N-1>X-1;速生期的高、径生长曲线均呈双峰型,但柠条锦鸡儿径生长峰值滞后于高生长半个月左右,小叶锦鸡儿径生长与高生长同步或滞后半月左右。

| Abstract: | Logistic curve was adopted to fit the growth of seedling height and ground diameter of Caragana korshinskii and C.microphylla with different provenances.Two inflection points and length of fast growth time were estimated.The results showed that height growth and diameter growth of C.korshinskii and C.microphylla were in accordance with S curve.The annual growth included three phases: initial stage of growth,fast-growing time and lignifications time.The beginning of diameter growth of fast-growing time was e... |
