摘要
采用单因素随机区组设计法和大型非称重式蒸渗仪法,在甘南高原地区研究了灌溉量对匙叶翼首草生长、产量和品质的影响。结果表明:随着灌溉量由0mm增至300mm,匙叶翼首草根长、根径、干物质的积累呈现增大的趋势,鲜根的产量由7 087.50kg/hm2逐渐提高至12 429.17kg/hm2,且灌溉量为300mm的产量最高,品质也最优。
Effect of irrigation quantity（IQ） on growth,yield and quality of Pterocephalus hookeri（C.B.Clarke） Diels in Gannan plateau area,with the single factor randomized block and large scale no-weight-lysimeter were studied.The results showed that IQ improved from 0 mm to 400 mm,the root length,root diameter and dry matte showed an increasing trend,and fresh root yields of Pterocephalus hookeri（C.B.Clarke） Diels improved from 7 087.50 kg/hm2 to 12 429.17 kg/hm2.And the production of irrigation amount of 300 mm was the highest,quality was the best too.
