摘要: <正>以土壤盆栽作对照,着重对切花月季试管苗在自动滴灌条件下、不同无土基质上的早期生物量、根系人为受损后的生长潜能、植株个体发育、鲜切花产量形成动态、以及枝叶群体结构等进行研究,结果表明:岩棉培和无土基质袋培的植株生长发育明显加快,根系再生能力强,到花日数分别提早6.3d和4.cd;其群体枝叶空间分布相对合理,各群体高度的消光系数K小而接近,叶面积指数分别高达15.6和14.6,高于对照近3倍;平均每株的鲜切花增产104%和97%,且花枝颀长,品质指数较高,经济效益显著。

Abstract: in contrast with the soil potting culture,the biomasses of cut flower roses in vitro duringtheir seedling stage,the root growth capacity after injured artificially,the dynamic formation ofbloom yield,and the population structure in shoots and leaves, and so on, have been conducted.Theexperimental results indicated that:the plant growth and developement existed in both rockwool cultureand substrate culture was obviously promoted, their root growth capacity (RGC) was muchstronger, and the time from axillary buds to blooms was 6. 3 and 4. 0 days ahead respectively; thespace distribution of shoots and leaves in population structure was relatively reasonable, the extinctioncoefficient K in different layer heights was small and similar, and the leaf aera index reached to 15. 6and 14. 6 respectively, which was 3 times that in the contrast; the mean blooms yield per plant increased not only to 104% and 97 % respectively, but also with a longer shoots and higher quality index.
