摘　　要：以43个紫花苜蓿品种为试材,通过监测各品种发芽率、越冬率、物候期、生长速度及田间生长表现,初步筛选出15个相对表现优良、适应性较强的品种,进而研究初筛品种在覆膜穴播、年刈割三茬的条件下,其株高、分枝数、叶茎比、鲜干比等农艺性状表现、生物产量差异及经济效益分析。结果表明:甘农三号、三得利、WL343HQ、巨能7和龙葳6010这5个紫花苜蓿品种在株高、叶茎比、鲜干比和生物产量等方面较其他供试苜蓿品种表现突出,每公顷干草产量分别达18.21 t、17.63 t、17.58 t、17.47 t和17.11 t,每公顷纯收益分别为15954元、14862元、14292元、13488元和13104元,较对照品种陇东苜蓿,每公顷纯收益分别增加7320元、6228元、5658元、4854元和4470元,是当地实现高产的首选品种,具有较高的经济效益。In this study,43 alfalfa varieties were used as experimental materials,and the germination rate,overwintering rate,phenological period,growth rate and field growth performance of each variety were monitored.We preliminarily screened 15 varieties with relatively good performance and strong adaptability,and then studied their plant height,number of branches,leaf-to-stem ratio,fresh-to-dry ratio,etc.Agronomic performance,biological yield difference and economic benefit analysis.The results showed that five alfalfa varieties,Gannong 3,Suntory,WL343HQ,Juneng 7 and Longwei 6010,performed better than other tested alfalfa varieties in terms of plant height,leaf-to-stem ratio,fresh-to-dry ratio,and biomass.Hay yields per hectare were 18.21 t,17.63 t,17.58 t,17.47 t and 17.11 t,and the net income per hectare were 15954 yuan,14862 yuan,14292 yuan,13488 yuan and 13104 yuan,respectively.For Longdong alfalfa,the net income per hectare increased by 7320 yuan,6228 yuan,5658 yuan,4854 yuan and 4470 yuan respectively.This is the preferred variety for local high-yielding,with high economic benefits.
