摘    要:探讨以不同体积比(0%,20%,40%,60%,80%,100%)混合的蚓粪与供试土壤基质对黑麦草绅士(Lolium perenne ‘Esquire’)和匍匐剪股颖帕特 (Agrostis stoloniferal ‘Puter’) 种子萌发及初期生长的影响,旨在为蚓粪能够更好地应用于草坪草建值提供更有力的科学依据.结果表明:黑麦草20%处理组的萌发率和发芽势最高,同时平均萌发时间最短,相比于对照提前了近1 d,且差异显著(P<0.05),但初期生长的叶片数和地上生物量在不同处理组之间无显著差异.匍匐剪股颖在20%处理下的平均萌发时间最短,生长初期60%处理下的叶片数显著多于对照,达到了3.01 片·株-1,且地上生物量最大,平均每株比对照高出0.42 mg.故在黑麦草种子萌发和初期生长过程中,蚓粪最适宜的添加体积比为20%,而匍匐剪股颖在种子萌发期的适宜蚓粪添加比为20%,而在初期生长中的添加比为60%.表明针对不同的草坪草及其不同生长阶段,应选择适宜的蚓粪添加量.

关 键 词:蚓粪  黑麦草  匍匐剪股颖  种子萌发  初期生长

Abstract:In order to provide scientific basis for well applying vermicompost in the establishment of turfgrass, the effects of incorporating vermicompost into soil in proportions of 0%,20%,40%, 60%,80%,100% (V/V) on the seed germination and early development of Lolium perenne ‘Esquire’ and Agrostis stoloniferal ‘Puter’ were investigated. The results showed that under the 20% proportion of vermicompost treatment, both the germination and germination energy of Lolium perenne arrived the highest value, which were 22.50% and 27.50% significantly higher than the control, respectively (P<0.05). However, the different treatments did not affect the numbers of leaves and aboveground dry weight of Lolium perenne. To Agrostis stoloniferal, when the proportion of vermicomposr was 20%, the mean germination time was the shortest, and at the 60% proportion, the numbers of leaves 3.01 per plant were significantly higher than the control, the aboveground dry weight was significantly larger by 0.42 mg per plant than the control. So during the germination and early development of Lolium perenne, the suitable proportion of vermicompost was 20%. To Agrostis stoloniferal, the proper proportion was 20% during germination, and then turned to 60% in its early development. Therefore, different turfgrass and growth stages should be added the suitable proportion of vermicompost.
Keywords:Vermicompost  Lolium perenne  Agrostis stoloniferal  Seed germination  Seedling growth
