【摘要】 经过3年的试验,对引自美国和加拿大的9种草坪型羊茅在引黄灌区的物候期、生长特性以及种子生产性能进行了较为系统的研究。结果表明,所有参试品种在银川地区均可良好结实,但结实性能差异极大,Lowgrow,Arid高羊茅和Ruby及Boreal紫羊茅的种子产量最高。通过试验认为,在宁夏引黄灌区建立草坪型羊茅种子生产基地是完全可行。更多还原

【Abstract】 The phenology,growing characteristics and seed productivities of 9 varieties of turftype tall fescue(Festuca ovina)and red fescue(Festuca rubra),which introduced from United states and Canadawere systemicallystudied in the Yellow River irrigation area of Ningxia through 3year experiments. It is showed that all of the tested varieties can produce seed in Yinchuan region,and the fecundity rates are different significantly. The tall fescue varieties of"Lowgrow"and"Arid"produce the highest seed yields,and the red fescue varieties of"Ruby"and"Boreal"produce the highest seed yields. It is possible to establish seed productionbase for turftype tall fescue and red fuscus in the irrigation area of Ningxia?更多还原
