彩色马蹄莲引种栽培技术初探

Preliminary study on cultural technique of colour calla lily

对14个从荷兰引进的彩色马蹄莲品种,从种植时间、栽培基质、栽培密度和株型调控等研究其栽培技术,结果表明,春季的种植时间越晚,生育期越短,但对生长有一定不良影响,如使切花花枝变短等。用泥炭+河沙+园土(3∶1∶1)基质栽培可以生产出品质优良的切花和观赏价值高的盆花;合理密植可提高单位面积的切花产量而不影响质量,对于盆花则应根据株型来选择适宜的密度;用多效唑处理可使植株矮化,但各品种对多效唑的敏感度不同,多数品种的适宜质量浓度为1000mg/L。

To grasp t he cultural technique,the period between planting and flowering,cultural medium, cultural density and plant dwarfing of 1 4 colour calla lily varieties introduced from Holland were studied about The resu lt indicated that the later planting dat e in spring,the shorter the period betwe en planting and flowering,but their grow th was affected negatively,including the length of cut flower stalks becomes sho rter.The medium made up of peat,sand and soil(3∶1∶1) helped produce cut flowers and pot flowers of high quality.The prod uction of cut flowers per unit area was i ncreased and the quality was little affe cted in high planting density.But to pot flowers the choice of planting density should be based on different cultivars.PP 333 can make the plants dwarf but the se nsitivity of each variety to PP333 was di fferent.The suitable concentration to mo st varieties was 1 000 mg/L.
