| 摘 要： | 采用单因素随机区组法,在甘南高原地区研究了红芪剪茎高度对其生长和产量的影响.结果表明:红芪剪茎比不剪茎能极显著地提高产量,且红芪在7月下旬现蕾前进行剪茎,留茎高度50 cm的主根长、根径、单株根干物质积累、折干率、一等率等经济性状和产量最高,且比CK增产14.07％(p＜0.01).

| Abstract: | Using single factor randomized block method to study the effects of height of kept stem on growth and yield of Hedysarum polybotrys Hand.-Mazz in Gannan plateau area.The results showed that cutting stem of Hedysarum polybotrys Hand.-Mazz can extremely significant increase yield in comparison with non-cutting stem;the economic traits(main root length,root diameter,root dry matter accumulation per plant,dry discount rate,first-class rate and etc.) and the yield of Hedysarum polybotrys Hand.-Mazz were the high... |
