图5. 不同磷高效利用杉木在不同处理时间的根冠比比较(平均值±标准偏差)。A, M1的根冠比。B, M4的根冠比。L-P代表低磷处理, H-P代表高磷对照。不同小写字母表示低磷处理条件下不同处理时间的根冠比差异达到显著水平(p < 0.05), 不同大写字母表示高磷对照条件下不同处理时间的根冠比差异达到显著水平(p < 0.05)。
Fig. 5. Root/shoot ratio of different Cunninghamia lanceolata with different high P-use efficiency at different sampling periods (mean ± SD). A, Root/shoot ratio of M1. B, Root/shoot ratio of M4. L-P and H-P represent the low and high P treatments, respectively. Different lower- and upper-case letters indicate significant differences (p < 0.05) across different treatment periods under L-P and H-P conditions, respectively.
