| 摘 要： | 为了给油茶林施肥管理提供科学依据,通过不同模式施肥,对油茶叶片生长和叶片养分含量进行研究,探讨油茶叶片各生长指标与叶片养分含量之间的关系。结果表明:各模式对油茶叶片生长指标和叶片养分含量均有显著促进作用,叶形指数与其它指标有负显著相关性,比叶重与其它指标间有正显著相关性,叶片养分中N、P、K的含量与其它指标间均存在显著相关性,说明施肥模式与叶片生长间关系密切。各模式对油茶叶片的肥效作用由大到小排列依次为:M5、M4、M2、M3、M1、M0、CK。

Effects of different fertilization modes on growth and nutrient content in Camellia oleifera leaves |
| |
| Abstract: | In order to provides some scientific basis for fertilization and management of Camellia oleifera forest, growth status and nutrient contents in C. oleifera leaves under different fertilization modes were studied, and relationship of the growth indexes and nutrient content in C. oleifera leaves was discussed. The results showed that the fertilization modes could significantly improve the growth indexes and nutrient contents in C. oleifera leaves, leaf shape index had significantly negative correlation with the other indexes, specific leaf weight had significantly positive correlation with the other indexes, and N, P, and K contents in leaves had significantly positive correlation with the other indexes. So There was a close correlation between fertilization model and leaf growth. Based on the effects on C. oleifera leaves from high to low, the order of the models was M5, M4, M2, M3, M1, M0, CK. |
