摘要:
本文运用异速生长分析法探讨了水竹Phyllostachysheteroclada秆型特征(地径、株高、枝下高和枝下节数)之间的关系和水竹秆形特征对不同经营措施(遮阴、施肥和灌溉处理)的可塑性响应。结果表明:(1)施肥显著降低了水竹地径与枝下高、枝下节数异速生长的SMA斜率,与不施肥处理相比,施肥处理水竹的枝下高、枝下节数的生长速率低于地径的生长速率。施肥未显著改变地径与株高的异速生长斜率(P>0.05),但施肥的SMA主轴在Y轴方向和共同斜率方向出现正向显著移动,即整体上施肥处理水竹的地径和株高比不施肥的更大;(2)遮阴使水竹地径与株高、枝下高、枝下节数异速生长的SMA斜率显著降低,表明遮阴使水竹株高、枝下高、枝下节数的生长速率均低于地径的生长速率,且在不施肥、不灌溉处理下,这种效应更为强烈;(3)不同经营措施对水竹秆形特征综合影响程度表现为遮阴>施肥>灌溉。遮阴和施肥对异速生长关系具有极显著的影响(P<0.001),斜率变异分别可达227%和210%,但灌溉处理未显著改变水竹地径与株高、枝下高、枝下节数异速生长的SMA斜率(P>0.05)。水竹地径与株高、枝下高、枝下节数的异速生长关系在不同经营措施下的不同表现,反映了水竹秆形特征对异质性生境具有可塑性响应,可为生产提供指导。
Abstract:
In July 2020, 6 sample plots with 20 m×30 m were established in wild Phyllostachys heteroclada forest with different altitude and different slope in Songyang, Zhejiang province. Experiments were carried out on shading, fertilization and irrigation and no treatment (CK). In March 2022, 5 quadrats with 5 m×8 m were set up in every sample plot and 5 Ph. heteroclada culm were random cut in each quadrat for investigation of ground diameter, height, clear bole height and clear bole nodes. The result demonstrated that fertilization significantly reduced the standardized major axis estimation (SMA) slope of allometric relation of ground diameter with clear bole height and clear bole nodes, indicating that the growth rate of clear bole height and clear bole nodes under fertilization was lower than that of no fertilization. Fertilization did not significantly change the allometric growth slope of ground diameter and height (P > 0.05), but the main axis of fertilization SMA moved positively in the y-axis direction and the common slope direction. Shading significantly reduced the SMA slope of ground diameter and height, clear bole height and clear bole nodes,indicating that shading made the growth rate of height, clear bole height and clear bole lower than that of ground diameter, and this effect was stronger without fertilization and irrigation. The comprehensive influence of different management measures on the culm form showed shading >fertilization > irrigation. Shading and fertilization had a strong effect on allometry (P < 0.001), and the slope variation was 227% and 210%, respectively. However, irrigation did not significantly change the SMA slope of ground diameter, height, clear bole height and clear bole nodes (P >0.05). The different performance of allometry of ground diameter with height, clear bole height and clear bole nodes under different management measures reflects the plasticity response of culm form properties to heterogeneous habitats.
