| 摘 要： | 采用＂311-A＂最优混合设计,通过盆栽试验,研究了氮、磷、钾肥对芳樟枝叶产量和含油率的影响。结果表明,氮有利于枝叶产量提高,钾有利于含油率的增加。芳樟枝叶产量及含油率均达到理想值,氮、磷、钾的用量分别为115.67 g·株^-1、33.19 g·株^-1、133.40 g·株^-1,相应枝叶产量为2.67 kg·株^-1,含油率为1.43%。故氮、磷、钾最佳的施肥配方为1︰0.29︰1.15。

| Abstract: | Adopting the ＂311 -A＂ optimum compound design, the effects of nitrogen, phosphorus and potassium on shoot yield and oil content of Cinnamomum camphora var. linaloolifera were studied. The results indicated that nitrogen was benefit for the increase of shoot yield, whereas potassium was helpful for the increase of oil rate. Applying nitrogen, phosphorus and potassium of 115.67 g, 33.19 g and 133.40 g per tree respectively, the corresponding shoot yield and oil content ratio were 2. 67 kg per tree and 1.43 % respectively. It was therefore concluded that the optimal fertilizer formula was 1 ： 0. 29 ： 1.15. |
