采用L9(34)正交实验设计,研究了温室盆栽和田间栽培条件下,不同氮、磷、钾施用水平对曼地亚红豆杉‘Hicksii’(Taxus media‘Hicksii’)生长及紫杉醇含量的影响。结果表明,不同的氮、磷、钾施用水平对曼地亚红豆杉‘Hicksii’盆栽苗和田间栽培苗的生长量、枝叶产量和紫杉醇含量有显著影响,影响效应从大至小依次为氮、磷、钾。根据生长综合指标确定最有利于曼地亚红豆杉幼苗生长的氮、磷、钾施用量分别为400、66和200 mg·L^{- 1};最有利于紫杉醇积累的氮、磷、钾施用量分别为200、66和133 mg·L^{- 1}。此外,曼地亚红豆杉‘Hicksii’田间栽培苗的生长量、枝叶产量和紫杉醇含量显著高于盆栽苗。

The effects of different fertilization levels of N, P and K on growth and taxol content of Taxus media `Hicksii' seedlings were studied by the orthogonal experiment design L<sub>9</sub>(3<sup>4</sup>) inpotculture and field culture conditions. The results show that the different fertilization levels of N, P and K have the remarkable influence on growth quantity, yield of branch and leaf and taxol content of T. media `Hicksii' seedlings, and the effect order from big to small is N, P, K. According to the growth overall desirability, the optimal fertilization level of N, P and K being beneficial to growth of T. media `Hicksii' seedlings is 400, 66 and 200mg·L<sup>- 1</sup>respectively; the optimal fertilization level of N, P and K being beneficial to taxol accumulation of T. media `Hicksii' seedlings is 200, 66 and133 mg·L^{- 1} respectively. Moreover, the growth quantity, the yield of branch and leaf and taxol content of T.media `Hicksii' seedlings cultivated in field are higher than that of the pot seedlings.
