摘要：为了实现对油茶的高效精准施肥,以普通油茶良种‘长林4号’盆栽大苗为试材,研究了不同施肥策略及复合肥不同氮、磷、钾配比对春梢生长及叶片主要矿质元素氮磷钾元素含量的影响。研究结果表明:复合肥和有机肥的施用量对春梢长度影响显著,而复合肥不同氮磷钾配比对春梢长度无显著影响;冬季有机肥的施用对春梢叶片氮磷钾矿质元素含量无显著影响,而不同复合肥施用量、氮磷钾配比和施用频次显著影响春梢叶片氮钾元素含量,对叶片磷元素的含量影响则不显著;冬季施用25 g/株有机肥、5月份施用N∶P2O5∶K2O配比为5∶1∶5的复合肥15 g/株,对促进油茶春梢生长、改善春梢叶片氮钾营养效果最佳。
In orderto realize efficient and accurate fertilization of Camellia oleifera, using containerized seedlings of improved cultivar of C. oleifera ＇Changlin 4＇ as materials, effects of different fertilization strategies and N, P, K proportion in compound fertilizer on spring shoot growth and contents of main mineral elements N, P, K in new leaves were researched. The results showed that the application amount of compound fertilizer and organic fertilizer had significant influences on the length of spring shoots, while different N, P, K proportion in compound fertilizer had no significant effect on the length of spring shoots. Organic fertilizer application in winter had no significant influence on N, P, K contents in new leaves of spring shoots. While application amount, N, P, K nutrient proportion and application frequency of compound fertilizer had significant effects on N and K contents in new leaves of spring shoots, and no significant effect on P content in new leaves. Overall, applying 25 g organic fertilizer per tree in winter and 15 g compound fertilizer per tree （N, P2O5, K20 proportion 5 ： 1 ： 5） in May was beneficial for spring shoots growth and improvement of N and K nutrients in new leaves.
