摘要
[目的]研究南通地区国兰的生长发育动态,为国兰的栽培管理提供理论基础。[方法]以春兰和蕙兰主栽品种为试材,定期观测叶芽、花芽的生长发育情况。[结果]春兰春芽(叶芽)快速生长期在4月中旬至6月下旬,蕙兰春芽(叶芽)旺盛生长期在4月中旬至7月中旬;春兰秋芽(叶芽)快速生长期在10月初至12月中旬;蕙兰秋芽(叶芽)旺盛生长期在10月初至12月下旬。春兰、蕙兰的花葶均在10月底出土,但春兰的花葶在1月底进入缓慢生长期,而蕙兰的花葶则在2月底才进入缓慢生长期。[结论]南通地区春兰和蕙兰的主要施肥期宜为:春季3月下旬至4月初,以氮肥为主;秋季9月中下旬,宜多施磷、钾肥。
[ Objective] The research aimed to study orchid＇ s growth and development in Nantong region thus providing theoretical basis for cultivating Chinese Orchids. [Methods] With Cymbidium goeringii and Cymbidium faberi as varieties for test materials, regular observations of leaf, bud, flower bud growth and development situations were made. [Result] The rapid growth period of Cymbidium goeringii spring bud （leaf bud） was from mid-April to late June. Strong growth of Cymbidium faberi spring bud （leaf bud） can be found from mid-April to mid-July; Rapid growth of Cymbidium goeringii autumn shoots （leaf bud） and Cymbidium faberi autumn shoots （leaf bud） can be observed from early October to mid-Decamber and from early October to late Decamber respectively, scape of both varieties unearth by the end of October; However, the scape of Cymbidium goeringii enters the slow growth period by the end of January, while the scape of Cymbidium faberi moved into the slow growth period by the end of February. [ Conclusion] For Nantong region, the best fertilizer （mainly nitrogen fertilizer） applying period for Cymbidium goeringii and Cymbidium faberi was from late March to early April in spring; From mid September to late autumn, more phosphorus and potassium fertilizer were advised.
