饲用油菜品种比较试验报告

Report on Comparative Test of Forage Rape Varieties

以饲用油菜饲油1号和豆科牧草兰箭3号箭筈豌豆、凉山光叶紫花苕为对照,对饲用油菜新品系饲油36的物候期、农艺性状、生产性能及品质等在川西北高原进行了品种比较试验。试验结果表明:饲油36与对照饲油1号生育期一致,在农艺性状上优于对照,具有植株高大、叶量丰富、分枝数多等特点;饲油36连续两年鲜草产量和干草产量平均值分别为36 607.07kg/hm^2和5 233.64 kg/hm^2,均显著高于对照(P<0.05);饲油36粗蛋白含量较高,可达21.2%,比对照饲油1号高4.8%,与供试豆科牧草相当。可见,饲油36具有高产优质饲草开发的潜力。

In this paper, Brassica campestris L. cv. Siyou No. 1 of forage rape and Vicia sativa L. cv. Lanjian No. 3 and Vicia villosa Roth var. glabrescens cv. Liangshan of leguminous forage were used as control. Comprehensively analysis on phennlogical period, agronomic traits, production performance and quality of new strain named Brassica campestris L. cv. Siyou No. 36 was conducted in Northwest Sichuan Plateau. The results showed that Siyou No. 36 was consistent with the control of Siyou No. 1 on phenological period, which had a better performance than the control of Siyou No. 1 on agronomic traits, such as taller height, richer leaves and more branches. The average values of fresh yield and hay yield of Siyou No. 36 were 36607.07 kg,/hm 2 and 5233.64 kg/hm2 for two consecutive years, respectively, which were significantly higher than the control varieties. In addition, Siyou 36, with the crude protein content of 21.2%, was significantly higher than the control of Siyou No. 1 , and almost the same as the tested leguminous forages. Therefore, Siyou 36 has development potential as a kind of high yield and good quality forage varieties.
