狗牙根在植被砼上的适应性研究

Study on Adaptability of Bermudagrass in Vegetation Concrete

通过观测发芽、分蘖及株高等指标,比较了狗牙根(Cynodon dactylon(L.)Pers.)4个品种(Jackpot、Hulled、Unhulled、Sahara)在植被砼上生长发育的差异性,结果表明Unhulled极显著优于其它3个品种,而Jackpot与Hulled相比,无显著差异,但它们极显著优于Sahara。通过观测4个草种在植被砼上的盖度、色泽、质地、成坪性等坪用性状指标,应用"九分制"评分法对各项指标评分,结果表明各草种成坪性的综合评定得分从高到低顺序为:Unhulled>Jackpot>Hulled>Sahara。供试的狗牙根4个品种在植被砼生境下,基本能完成整个生活史,有比较强的适应性,其中Unhulled适应性最强,其次是Jackpot,再次是Hulled,Sahara最差。

By observing morphological indexes (germination, tiller and height etc.) of 4 bermudagrass(Cynodon dactylon) varieties (Jackpot, Hulled, Unhulled, Sahara) in the vegetation concrete,the differences of their development were carried out. The results show that Unhulled shows differences to other varieties at 0.01 level;Jackpot shows no differences to Hulled at 0.05 level; but they show differences to Sahara at 001 level.Observing all tested materials’ turf-type characteristics in vegetation concrete,such as ...
