“苏特”燕麦品种比较试验报告

Comparative Test Report of Shooter Oat Varieties

通过连续两年对引种在四川地区的"苏特"燕麦与对照"青引2号"燕麦、"阿坝"燕麦进行了相关指标的观测比较。试验结果表明:在物候期方面,3个材料均能完成生育,但"苏特"相比两个对照材料晚40余天进入拔节期,且其两年平均生育周期也明显长于两份对照材料。在生长发育上,"苏特"株高为158.4cm,分别高于"青引2号"20.6 cm和"阿坝"燕麦15.7cm;在干草产量上,"苏特"为10905.76kg/hm^2,分别比"青引2号"和"阿坝"燕麦高出12.97%和16.29%(P<0.01)。"苏特"在抽穗期的粗蛋白含量为7.21%,高于"青引2号"的6.64%和"阿坝"燕麦的6.52%。"苏特"在该区域适应性强、生育期长、株高较高、干草产量高、适口性好等特点,综合评价最高,适宜在该区域推广。

Observation and comparison of related indicators were carried out for two consecutive years between the"Shooter"oats introduced in Sichuan,the control Qingyin No.2 oats and Aba oats.The test results showed that:on the phenological phase,all three materials could complete fertility,but Shooter oats entered the jointing stage more than 40 days later than the two control materials,and its two-year average fertility cycle was significantly longer than the two control materials.In terms of growth and development,the plant height of Shooter oats was 158.4 cm,which was 20.6 cm higher than that of Qingyin No.2 oats and 15.7 cm of Aba oats;In terms of hay production,Shooter oats was 10905.76 kg/hm^2,which was 12.97%and 16.29%higher than Qingyin No.2 oats and Aba oats,respectively(P<0.01).The crude protein content of Shooter oat at heading stage was 7.21%,which was higher than 6.64%in Qingyin No.2 oats and 6.52%in Aba oats.Shooter oats is highly adaptable in this region and has the characteristics of long growth period,high plant height,high hay yield and good palatability.The comprehensive evaluation is the highest and suitable for extension in the region.
