摘要
本文探讨了案头菊（Chrysanthemummorifolium（Ramat．）Tzvel．）的内涵，设立了有关的园艺指标。经过6年的试验，采用5000mg·L－1的B9作为矮化剂，从66个中国晚菊品种中筛选出了16个适合用来生产案头菊的中国晚菊品种，总结出了一套适合案头菊生产的技术措施。其具体做法是：每年5月至7月采用扦插法育苗，在定植后间隔6～10d进行叶面喷洒5000mg·L－1的B9直至现蕾。由于品种差异，供试材料对B9的反应各不相同。使用民会使案头菊花期后延，此问题可以采用5mg·L－1的GA3溶液涂抹花蕾予以解决。采用此种方法栽培的案头菊品质高，出圃率可达90％以上。
The definition of desk chrysanthemum (Chrysanthemum mordelium (Ramat.) Tzvel. ) was discussed and the horticultural standards of the desk chrysanthemum was established in this paper based on 6 years experiments. Applying 5 000 mg·L-1 B9 as a dwarfing agent treated chrysanthemum, the 16 Chinese late blooming cultivars have been screened from 66 Chinese late blooming cultivars. The technological step which suit to desk chrysanthemum product was summarized. The proposed method is as follows: the young shoots were cultivated from May to July. After fix planting to flower bud appeared, the chrysanthemum were treated for foliage spray with 5 000 mg·L-1 B9 solution intervals 5 to 10 days. Owing to difference of cultivars. The chrysanthemum had different reaction for B9. Aplying B9, the blooming time of the desk chrysanthemum could be delayed. The phenomenon could be solved brushing trealment on flower bud with 5 mg·L-1 GA3 solution. A good quality desk chrysanthemum was cultivated, and rate of finished product in excess of 90% was obtained.
