摘要： 为探讨高羊茅（Festuca arundinacea）无土草皮生产的适宜播种量,减少生产成本的投入,通过盆栽试验分析了5种播种量（10 g·m-2,20 g·m-2,30 g·m-2,40 g·m-2,50 g·m-2）对高羊茅无土草皮质量的影响。结果表明：播种量显著影响高羊茅无土草皮表观质量与生物量,播种量从10 g·m-2增加到50 g·m-2,草皮高度与颜色显著降低（P<0.05）；播种量从10 g·m-2增加到30 g·m-2,草皮密度、质地、盖度与生物量均显著增加（P<0.05）,当播种量大于30 g·m-2时,草皮的颜色、密度、盖度、均一度与生物量差异不再显著；播种量从10 g·m-2增加到50 g·m-2,草皮均一度呈增加趋势,但各处理间无显著差异。隶属函数综合分析表明,草皮质量随播种量增加而增加,播种量为50 g·m-2时所获得的草皮质量最高,其次为30 g·m-2。综合考虑各项指标,在节约成本且能获得优质草皮的基础上,生产高羊茅无土草皮的播种量以30 g·m-2左右为宜。

Abstract: In order to investigate the suitable sowing rate of Festuca arundinacea soilless sod, the effects of five sowing rates （10 g·m-2, 20 g·m-2, 30 g·m-2, 40 g·m-2, 50 g·m-2） on the quality of Festuca arundinacea soilless sod were analyzed by pot experiment. The results showed that the apparent quality and biomass of Festuca arundinacea soilless sod were significantly affected by increasing sowing amount, while the height and color of sod significantly decreased （P<0.05） , and the density, texture, coverage and biomass of sod significantly increased （P<0.05）. The uniformity of sod showed an increasing trend, but there was no significant difference among different treatments. When the sowing amount was greater than 30 g·m-2, the differences in color, density, coverage, uniformity and biomass of sod were not significant. According to the comprehensive analysis of membership function, sod comprehensive quality increased with the increase of sowing amount. Sod comprehensive quality was the highest when seeding amount was 50 g·m-2, followed by 30 g·m-2. On the basis of cost saving and high quality sod, 30 g·m-2 was the best planting amount for Festuca arundinacea soilless sod in North China.
