摘　　要：[目的]解决云南省会泽县草食畜生产中饲草短缺的问题,筛选出适宜的饲草品种开展推广种植。[方法]引进冬春季饲草品种5个(爱沃126燕麦、贝勒Ⅱ燕麦、青引1号燕麦、优能小黑麦、麦丰小黑麦)开展冬春季饲草品种种植筛选试验,采用随机区组设计,4个重复,其中3个重复用于农艺性状指标测定,1个重复用于物候期观测,开展物候期监测、农艺性状指标测定和养分含量分析。[结果]2个小黑麦品种的株高显著高于3个燕麦品种;青引1号燕麦和爱沃126燕麦的干物质产量显著高于其他3个供试品种,分别达到16536、16176 kg/hm^(2);3个燕麦品种的粗蛋白、粗脂肪、灰分、钙、磷养分含量均高于2个小黑麦品种。[结论]农艺及养分指标综合比较,青引1号燕麦和爱沃126燕麦产量较高,品质较好,适宜作为试验地及会泽类似气候地区冬春季饲草的推广种植品种。[Objectives]To screen out suitable forage grass varieties for promotion and planting to solve the problem of forage grass shortage in herbivorous livestock production in Huize County,Yunnan Province.[Methods]5 forage grass varieties in winter and spring including Everleaf 126 oat,BaylorⅡoat,Qingyin No.1 oat,Youneng triticale,and Maifeng triticale were introduced to conduct a screening and planting experiment for forage grass varieties in winter and spring.A randomized block with 4 replicates was designed,among which 3 replicates were used for measuring the indexes of agronomic traits and 1 replicate was used for observing phenological period.The phenological monitoring,measuring the indexes of agronomic traits,and analyzing the content of nutrients were conducted.[Results]The plant height of two triticale varieties was significantly higher than that of three oat varieties.The dry matter yield of Qingyin No.1 oat and Everleaf 126 oat was significantly higher than that of the other three varieties tested,reaching 16536 kg/hm^(2) and 16176 kg/hm^(2),respectively.The content of crude protein,crude fat,ash,calcium,and phosphorus nutrient in the three oat varieties was higher than that in the two triticale varieties.[Conclusions]Qingyin No.1 Oat and Everleaf 126 oat had higher yield and better quality based on a comprehensive comparison of agronomic and nutrient indexes,making them as suitable forage grass varieties for promotion and planting in winter and spring in experimental sites and similar climate areas in Huize County,Yunnan Province.
