就龙须草草地不同田间持水量和不同淹水时期对龙须草分蘖发生、叶片生长和产量形成的影响进行了比较研究,结果表明,保持龙须草草地田间持水量在70%～80%有利于龙须草分蘖发生、叶片生长和产量形成,而田间持水量过高(90%～100%)或过低(40%～50%)都不利于龙须草分蘖发生、叶片生长和产量形成;龙须草生育过程中,大田淹水不利于龙须草分蘖发生、叶片生长和产量形成,尤其是在6月下旬至7月上旬淹水产生的不利影响程度最为严重.

The influence of different soil-water content and water-logging times on tiller emergency, leaf growth and yield formation was studied. The results showed: keeping soil-water content on 70%-80% was favorable to tiller emergency, leaf growth and yield formation of Eulaliopsis binata. Water-logging could influence Eulaliopsis binata growth, especially during the period with active Eulalio...
