摘　　要：以青绿苔草(Carex breviculmis)为试验材料,研究了5个播种量(5、10、15、20、25 g·m^(-2))对青绿苔草无土草皮质量的影响。结果表明,播种量显著影响草皮质量,随着播种量增加,草皮密度、质地、盖度、均一度等指标均显著提升(P<0.05),地上部生物量无显著变化(P>0.05),地下部生物量先增加后减少(P<0.05)。通过层次分析法和灰色关联度分析法综合评价得出,随着播种量增加,青绿苔草无土草皮质量先增加后减少,20 g·m^(-2)处理无论在等权还是加权评价下均排名第一,但15与20 g·m^(-2)两个处理除地下部生物量外,其余指标均无显著差异,因此在本研究条件下,生产青绿苔草无土草皮的适宜播种量应当控制在15~20 g·m^(-2)。The effects of five sowing amounts(5,10,15,20,and 25 g·m^(-2))on the quality of Carex breviculmis soilless turf were studied.The results showed that the seeding rates significantly affected turf quality.With the increase of the seeding rate,the scores of turf density,texture,coverage,average degree,and other indicators were significantly increased(P<0.05),while aboveground biomass showed no significant change(P>0.05).Underground biomass increased first and then decreased(P<0.05).According to a comprehensive evaluation system using the analytic hierarchy process and grey correlation analysis method,with the increase of the seeding amount,the quality of the soilless turf of C.breviculmis increased first and then decreased,and the treatment of 20 g·m^(-2) ranked first in terms of equal weight or weight.However,there was no significant difference in the other indicators between the 15 and 20 g·m^(-2) treatments,except for underground biomass.Therefore,under the conditions of this experiment,the appropriate sowing rate for the production of soilless grass of green Carex moss should be controlled at 15~20 g·m^(-2).
