Effects of Different Overwinter Measures on Growth and Yield of Pennisetum purpureum

研究了不同越冬措施对矮象草生长状况和生产性能的影响。结果表明：相对于覆草、盖土和对照，覆膜措施更能有效提高矮象草的返青率、鲜草产量和品质；茎粗和单株叶片数是预测鲜草产量的主要指标，与鲜草产量呈正相关关系。

Effects of different overwinter measures on growth and yield of Pennisetum purpureum were studied. The result showed that rectorial measure is more effective to enhance regreening ratio, yield and quality of Pennisetum purpureum than those of covering grass, covering soil and comparison. Cauline width and leaves quantity express fresh grass yield exactly and are positive relative to the latter.
