内蒙古地区10个燕麦品种生产性能及营养品质的比较研究

Comparative study on production performance and nutritional quality of ten oat varieties in Inner Mongolia

试验旨在筛选出适宜内蒙古土默特右旗种植的优质燕麦品种。以10个燕麦品种为供试材料,对其物候期、农艺性状、产量性状和营养品质等进行分析。结果显示,10个燕麦品种均能够在试验区完成整个生长发育过程,生育期87~110 d。定燕2号株高显著高于其他品种(P<0.05),而蒙燕1号株高显著低于其他品种(P<0.05)。坝莜18号籽粒产量最高,坝燕6号次之,而远杂1号显著低于其他品种(P<0.05)。定燕2号与坝莜18号干草产量显著高于其他品种(P<0.05),而远杂1号显著低于其他所有品种(P<0.05)。GL381粗蛋白含量最高,魁北克粗蛋白含量最低。粗脂肪含量最高的是坝莜3号,最低的是蒙燕1号。定燕2号粗纤维含量最高,坝莜3号粗纤维含量最低。远杂1号粗灰分含量显著高于其他品种(P<0.05),魁北克粗灰分含量显著低于其他品种(P<0.05)。定燕2号酸性洗涤纤维含量最高,显著高于除魁北克之外的其他燕麦品种(P<0.05),最低的是远杂1号。定燕2号的中性洗涤纤维含量显著高于其他品种(P<0.05),坝莜3号显著低于其他品种(P<0.05)。坝莜3号相对饲喂价值最高,为107.67,定燕2号最低。灰色关联度综合分析显示,张燕4号、坝莜18号和坝莜3号生产性能和营养品质综合表现较好。研究表明,张燕4号、坝莜18号和坝莜3号适宜在土默特右旗及其周边地区种植及推广。

The aim of the experiment was to screen out high quality oat varieties suitable for planting in Tumet Right Banner,Inner Mongolia.Ten oat varieties were used as test materials,and their phenological period,agronomic characters,yield characters and nutritional quality were analyzed.The results showed that 10 oat varieties could complete the whole growth and development process in experimental area,and the growth period was 87-110 d.The plant height of Dingyan No.2 was significantly higher than that of other varieties(P<0.05),while the plant height of Mengyan No.1 was significantly lower than that of all other varieties(P<0.05).The grain yield of Bayou No.18 was the highest,followed by Bayan No.6,and Yuanza No.1 was significantly lower than that of other varieties(P<0.05).The hay yield of Dingyan No.2 and Bayou No.18 was significantly higher than that of other varieties(P<0.05),while that of Yuanza No.1 was significantly lower than that of all other varieties(P<0.05).GL381 had the highest crude protein content and Quebec had the lowest crude protein content.The highest crude fat content was Baoyou No.3,and the lowest was Mengyan No.1 and Dingyan No.2 crude fiber content was the highest,Bayou No.3 crude fiber content was the lowest.The crude ash content of Yuanza No.1 was significantly higher than that of other varieties(P<0.05),and the crude ash content of Quebec was significantly lower than that of other varieties(P<0.05).Dingyan No.2 had the highest acid detergent fiber content,which was significantly higher than that of other oat varieties except Quebec(P<0.05),and the lowest was Yuanza No.1.The neutral detergent fiber content of Dingyan No.2 was significantly higher than that of other varieties(P<0.05),and Bayou No.3 was significantly lower than that of other varieties(P<0.05).Bayou No.3 had the highest relative feeding value(107.67),while Dingyan No.2 had the lowest.The comprehensive analysis of grey correlation degree showed that Zhangyan No.4,Bayou No.18 and Bayou No.3 had better performance in terms of production performance and nutritional quality.The study indicates that Zhangyan No.4,Bayou No.18 and Bayou No.3 are suitable for planting and promoting in Tumet Right Banner and its surrounding areas.
