摘　　要：用蛭石、珍珠岩、草炭、腐熟鸡粪、腐熟猪粪配制育苗基质,在温室条件下研究其对翠菊[Calliste-phus chinensis(L.)Nees]幼苗质量的影响。综合分析结果表明,翠菊苗在处理3(草炭∶蛭石∶珍珠岩∶腐熟鸡粪为3∶3∶2∶2)基质上生长最好。苗期指标显示,生长在处理3基质配方上的苗全株干重为1 440.21mg、地下干重为406.56 mg、茎粗为0.37 cm、株高为7.22 cm、壮苗指数为1 367.43、叶绿素含量为2.82mg.dm-2、光合速率达到5.39μmolCO2.m-2.s-1,差异均达到显著水平。The influence of cultivating media containing different proportions of vermiculite,pearlite,peat,well-composted chicken manure,or well-composted hog waste on the seedling quality of China-aster [Callistephus chinensis（L.）Nees] was studied in greenhouse conditions.The dry weight,stem diameter,seedling height,the strong seedling index,photosynthesis rate,and chlorophyll contents were measured.The results indicated that the growth of the China-aster seedlings was the best in the treatment 3 containing vermiculite, peat, well-composted chicken manure, and pearlite at the ratio of 3：3：2：2. The total seedling dry weight, underground portion dry weight, stem diameter, seedling height, strong seedling index, chlorophyll content, and photosynthesis rate were 1440.21 mg,406.56 mg,0.37 cm,7.22 cm, 1 367.43,2.82 mg.dm-2,5.39 μmol（CO2） ·m-2·s-1 respectively.
