摘　　要：[目的]阐明鹿茸草物候期和生长更新特征。[方法]采用野外观测和室内试验相结合的方法,对其物候期、营养和生殖生长动态进行调查分析。[结果]在1年中,鹿茸草2月上旬开始萌芽,9月下旬后逐渐停止生长,每株植株平均萌发新枝数量为31.67个,枝条平均长度为19.44 cm。鹿茸草花期自3月上旬开始至6月上旬结束,种子成熟期晚于花期15 d。鹿茸草每植株平均结种数1 053个,年均更新幼苗3.42株;鹿茸草种子25℃培养条件下7 d开始种子萌发,12 d时达到萌发峰值,萌芽率为12.76%。[结论]该研究结果可为鹿茸草的人工育苗栽培提供依据。[Objective]Phenophase and growth characteristics of Monochasma sheareri Maxim were described.[Method]Phenophase,nutrition and reproductive growth of Monochasma sheareri Maxim were investigated based on the field investigation and indoor observation combining method.[Result]In a year,Monochasma sheareri Maxim started to sprout in the first ten-day period of February and stop growth in the last ten-day period of September.The average number of new steams of Monochasma sheareri Maxim were 31.67,average value at the length was 19.44 cm.It bloomed from the first ten days of March to the first ten days of June.The seed maturity was later 15 d than flowering.Average seed number in Monochasma sheareri Maxim was 1 053,it reproduced 3.42 seedlings per year.Seed of Monochasma sheareri Maxim began to germinate after culturing 7 days at 25℃,the maximal germination rate of Monochasma sheareri Maxim seed was 12.76%after culturing 12 days.[Conclusion]The research results can provide the basis for the bionic seedlings and cultivation of Monochasma sheareri Maxim.
