避光预处理和营养液栽培对水仙观赏价值的影响

Effect of Dark Pretreatment on the Value of View and Admire of Narcissus with Hoagland Solution Culture

试验探讨不同处理营养液栽培对水仙观赏品质的影响,为实际生产提供参考。试验方法是采用清水栽培、不避光预处理霍格兰溶液栽培为双对照,避光预处理7 d后用霍格兰溶液培养中国水仙,结果显示:处理水仙植株根系健壮、嫩白,叶片鲜绿厚实,根长/根径比及叶长/叶宽度比明显减小,与不避光预处理霍格兰溶液培养差异显著(P<0.05),与清水对照之间有极显著的差异(P<0.01),花梗数、每梗花朵数、花冠外径、花期与不避光处理营养液栽培对照无差异(P>0.05),与清水对照之间都有极显著的差异(P<0.01),花期延长4 d左右;观赏价值明显提高。

In the experiment, the growth indexes of Narcissus tazetta var. Chinensis Beem cultured in Hoagland solution were tested with dark pretreatment for 7 d. The results showed that the roots were stronger, tender and whiter, the leaves were more fresh-green and thicker. The ratio of rood length and rod dia and of leaf length and leaf breadth minished distinctly（P〈0. 01）. In the numbers of pedicels on each plant and flowerlets on each spike, there was difference distinctly in treatment between control 1 （P〈0. 01）, but not difference distinctly in treatment between control 2 （P〉0.05）. All indexes of treatment and control 2 were compared with control 1. Florescence was prolonged about 4 d and the value of view and admire was enhanced also.
