[目的]进一步把握碎米荠的生长习性,栽培出符合要求的碎米荠品种.[方法]调查共设置17个样点,采用样方法和实测法,测量样地中碎米荠群落的地理坐标、海拔、坡向、坡度、郁闭度、盖度、群落结构和群落物种组成.[结果]在调查的群落中,共发现维管束植物有137种,62科,115属.其中草本植物占群落的主要组成部分,有111种,而灌木和乔木则比较少,只有26种.乔木层中占优势的是枫香(Liquidambar formosana)和香樟(Cinnamomum camphora),灌木层中是黄荆(Vitex negundo)和高粱泡(Rubus lamber-tianus),草本层中则是看麦娘(Alopecurus aequalis)、白茅(Imperata cylindrica)等.[结论]碎米荠适合生长在阳光充足、湿润通风、土壤肥沃、郁闭度低的坡地、荒田和溪边.“,”[Objective] Further grasp the growth habit of Cardamine and cultivate a variety that meet the requirements of Cardamine hirsuta L.. [Method] A total of 17 sampling sites were set up to measure the geographic coordinates, altitude, slope direction, slope, canopy coverage, coverage, community structure and composition of the species of the community of Cardamine hirsuta in the sample plots. [Results] A total of 137 species, 62 families and 115 genera of vascular plants were found in the investigated communities. There were 111 species of herbaceous plants, whereas only 26 species of shrubs and trees. The dominant tree layers were Liquidambar formosana and Cinnamomum Camphora, the dominant shrub layers were Vitex Negundo and Rubus Lambertianus, and the dominant herb layers were Alopecurus aequalis and Imperata cylindrica. [Conclusion] Cardamine cardamine was suitable for growing in sunny, moist, ventilated fertile soil, as well as in areas with low density of slope, barren fields and on the banks of streams.
