摘要： 本文研究在结缕草草坪复播高羊茅的方法。1994－1997年连续三年测定群落中高羊茅和结缕草的密度、盖度和频度,进而探讨较为适宜的复播方法和复播效果。结果表明,每平方米复播10g高羊茅种子加之划上深度3cm是较适宜的复播方法。增加复播量和加深划上深度,将增加高羊茅的优势度而减少结缕草的优势度,从而导致复合草坪群落趋向以高羊茅为优势的方向演替。

Abstract: A zoysiagrass (Zoysia japonica)turf autumn overseeding trial with tall fescue (Festucaarandnacea) under different beatments was first-time conducted in China from September 1994 toSeptember 1997.The turfgrass density, cover degree and frequency were measured to approach the opti-mum overseeding method and the turf community competition mechanism.Results showed that:10g/m2 tall fescue overseeding rate and 3cm vertical cutting depth was the optimum overseeding method amongthese four treatmemts; the increase in tall fescue overseedijg rate and vertical cutting depth could increasetall fescue density (P<0.05 ).cover degree and frequency(P>0.05) whereas it could reduced the zoysi-agrass density (P<0.01), cover degree(P<0.05)and boency (P<0.01); the unbalance competitionwould strengthen the tall fescue dominant degree and subsequently reduce the zoysiagrass domimant degreewithin the zoysiagrass-tall fescue polystand community and it would finally result in the turf communitysuccession tending to polystand community of tall fescue.
