| 摘 要： | 本项研究采用3种不同的刈割次数处理和7种不同的留茬高度处理。结果表明,刈割次数处理75天/次与30天/次、45天/次处理差异极显著(P<0.01),王草的单株鲜重472.07g,鲜草产量341666.7kg/hm2.a;不同刈割高度最佳处理为150cm,与30cm、60cm、90cm、120cm、180cm、210cm处理间差异极显著(P<0.01),王草的单株鲜重480.0g,鲜草产量332486.7kg/hm2.a。

| Abstract: | There are 3 treatments of cutting frequency and 7 treatments of cutting height in this study.The discrepancy is very prominence comparing 75d with 30d and 45d in cutting frequency(p<0.01),fresh weight of individual plant of king grass(Pennisentum×P.americanum cv.)is 472.07g,yield of fresh grass is 341 666.7kg/hm2.a;the best treatment of cutting height is 150cm,the discrepancy is very prominence comparing with 30cm?60cm?90cm?120cm?180cm?210cm,fresh weight of individual plant of king grass is 480.0g,yield of fresh grass is 332486.7 kg/hm2.a. |
