通过盆栽方式，采用不同体积混合配比的泥炭、椰糠、陶粒、树皮基质试验，以N、 P、 K3元素3水平设置了正交施肥试验，测定植株的生长状况、叶片养分及发病情况，分析了不同栽培基质和施肥处理对‘霞光’生长特性的影响。结果表明，混合栽培基质对虎雪兰‘霞光’的生长较单一的基质效果好，以1/4树皮＋1/4泥炭＋1/4椰糠＋1/4陶粒混合基质植株的株高、假鳞茎、叶面积和根系生长效果最佳；外施氮、磷、钾肥最佳组合为N1 P2 K3，即NH4 NO3、 NaH2 PO4和KCl含量分别为1.25 mmol/L、0.456 mmol/L和2.62 mmol/L，有利于虎雪兰‘霞光’植株的营养生长，且设施栽培中发病率较低。

In order to study the effects of different cultivated media and fertilizers on the growth of new Cymbidum cultivar ‘Xiaguang ’ , cultivated media experiments were carried out in pots by using different ratio of mixed media (bog muck, coconut shell, ceramsite and tree bark) , at the same time the orthogonal fertilization experiments were also conducted at different levels of N , P, K.The results showed that mixed media had better effect on the growth of ‘Xiaguang ’ than sole media , the mixed media using 1/4 tree bark+1/4 bog muck+1/4 coconut shell+1/4 ceramsite was the most effective to plant growth .The optimum N、 P、 K combination was N 1 P2 K3 , the content of NH 4 NO3 , NaH2 PO4 and KCl was 1.25 mmol/L, 0.456 mmol/L and 2.62 mmol/L respectively , by which the incidence was relatively low .
