| 摘 要： | 为了解不同肥料和不同浓度芸苔素内酯对油茶下一年春叶养分等指标的影响,选择长林4号、18号和166号优良无性系油茶品种,对其进行施肥（生物有机肥、油茶专用肥、复合肥）及叶面喷施芸苔素内酯的正交试验。结果表明：油茶春叶叶绿素SPAD值最高处理组合是长林4号、每株施生物有机肥1 kg和喷0.033 mg.kg-1芸苔素内酯;油茶春叶干物质含量最高的处理组合是长林18品系、每株施油茶专用肥0.5 kg和喷0.033 mg.kg-1芸苔素内酯;油茶春叶中氮和磷含量最高的处理组合是长林18品系、每株施油茶专用肥0.5 kg和喷0.033 mg.kg-1芸苔素内酯;叶片钾含量最高的处理组合是长林4品系、每株施生物有机肥1 g和喷0.067 mg.kg-1芸苔素内酯;钾对油茶春叶叶绿素SPAD值贡献率最高,氮对春叶干物质积累贡献率最高。

| Abstract: | In order to study the influence of fertilization and BRs on nutrient index of spring leaves of Camellia oleifera, L9 （ 34） orthogo- nal test design was used on applying organic fertilizer, special fertilizer of Camellia oleifera,compound fertilizer and spraying 0.067 mg.kg-1, 0.033 mg. kg-1 and 0.020 mg- kg-1 concentration of BRs on five years old Chang-Lin 4, 18 and 166 Camellia oleifera. Results were as follow： （ 1 ） The highest spring leaves SPAD value＇ s treatment combination was Chang-Lin4, treating with 1 kg/tree organic fertilizer and 0.033 mg.kg＇ BRs;（2）The highest dry matter content of spring leaves treatment combination was Chang-Linl 8,treating with 0.5 kg/tree specialty fertilizer of Camellia oleifera and 0.033 mg. kg-1 BRs; （3） The highest N and P content of spring leaves treatment combination was Chang-Linl8, treating with specialty fertilizer and 0.033 mg·kg-1 BRs. The highest K content of spring leaves treatment combina- tion was Chang-Lin4, treating with organic fertilizer and 0.067 mg·kg-1 BRs; （4） The maximum contribution rate on SPAD value of spring leaves was K, and the maximum contribution rate on dry matter of spring leaves was N. |
