以栽植3 a的乌头株丛为研究对象,探讨了3种种植密度(株行距10 cm×10 cm、8 cm×8 cm和5 cm×5 cm)对乌头生长发育的影响.结果表明,随密度增大,乌头的株高、茎粗、花序长度和花朵大小呈减少趋势,而叶面积指数呈增加趋势;在越夏时,密度越大叶片衰亡比例越高.综合植株的健壮程度、开花质量和群体花产量,认为最适宜乌头园林应用的密度是8 cm×8 cm.%Effects of different plant densities on growth and development of three years old Aconitum carmichaeli were studied. With an increase of plant density, plant height, stem diameter, inflorescence length, and flower size were reduced, while the leaf area index showed an increasing trend. The proportion of leaf decay increased with an increase of density in summer. Considering the extent of robust plants, flowering quality, and volume of groups flowers, the best plants density was a spacing of 8 cm× 8 cm in the landscape.
