摘要
探讨夏季遮荫、冬季保温、喷雾、修剪等因素对鹤望兰切花产量与质量的影响,结果表明:夏季遮荫对切花产量与一级花率影响不显著,但比对照二、三级花率提高28.6%;冬季保温栽培能显著提高12月—翌年3月切花产量,比露地栽培提高182.4%,二、三级花率也提高19.1%;对大于25株/丛、10年龄的植株采用留10￣19株的修剪方式全年产量比对照降低了15.1%,但能显著提高切花质量,一级花率比对照提高105.2%;采用修剪结合夏季遮荫、冬季保温、喷雾等处理措施既能提高鹤望兰切花年产花量,比修剪后露地栽培提高30.0%,也能提高切花质量,其中一级花率提高37.3%。
Shading in summer, heat preservation in winter, spraying and pruning treatment were conducted to study their effects on the cut flower yield and quality of Strelitzia reginae, The results showed that shading in summer had no significant effect on the cut flower yield and its first class flower rate, but the second and third class flower rate was increased by 28.6% compared with the opening field; Heat preservation in winter could significantly increase the yield from December of this year to March of the coming year, the yield raised by 182.4% and 19.1% higher in the second and third class rate than that of opening field . When pruning treatment was employed to the 10-age plants, 10-19 individuals were remained in a cluster included in more than 25 individuals, then the yield of the whole year was decreased by 15.1% while the cut flower quality was significantly increased and the first class flower rate was increased by 105.2% compared with the no treatment; With the combination of shading in summer, heat preservation in winter, spraying and pruning treatment, both the whole yield of the cut flower was increased by 30.0% higher than that of opening field after pruning in a year , and the quality was raised, among which the first class flower rate was raised by 37.3%.
