几种冷季型草种直播建坪和营养体建坪方法的比较研究

Comparative Studies on Direct Planting Measures and Nutritive Substances for the Establishment of Lawngrass Lands by Several Cold Season Grass Species

以８种冷季型草种为材料对２种建坪方法从盖度、成坪时间、成坪质量及坪用性状等方面进行综合比较，结果表明：营养体建坪能明显提高草坪盖度，增加草坪草种苗地上和地下生物量，缩短成坪时间，直播建坪成坪时间慢，但成坪质量高。通常情况下２种方法依待建草坪类型而采用。

By using 8 cold season grass species as testing materials,the authors were studying comprehensively in comparing two lawngrass species construction on coverage,time of lawngrass make-up,quality of lawngrass formation and characters of lawngrass usage and so on, the results indicated that the nutritive lawngrass construction was not only able to raise the coverage of lawngrass prominently;increase the seedling of lawngrass species on both the biomasses of aboveground and underground parts;meantimely shorten the time-duration of lawngrass make-up as well as lengthening the time of lawngrass make-up directly, but also improve the quality of Lawngrass make-up. On the basis of general condition, these two methods would be able to be used for the typing construction of lawngrass on success.
