冀北冷凉山区燕麦品种引种试验

Introduction Experiment of Oat Varieties in Cold Mountain Area of Northern Hebei Province

以筛选适合冀北冷凉山区种植的粮饲兼用燕麦品种为目标,对燕麦新品种进行适应性鉴定试验。结果表明,籽粒产量和干草产量最高的为坝燕4号,分别为2 509.5,30 435.0 kg/hm^2,抗病、抗倒等方面都相对较好;白燕15号的籽粒产量和干草产量分别为1 800.0,19 051.5 kg/hm^2,且生育期短;晋燕8号籽粒产量和干草产量相对较高,分别为1 468.5,19 857.0 kg/hm^2;坝莜18号的干草产量为24 613.5 kg/hm^2,仅次于坝燕4号。因此,坝燕4号、白燕15号、晋燕8号可作为粮饲兼用品种,坝莜18号可作为饲用优良品种在冀北冷凉山区推广。

To select the adaptation of grain-feeding oat varieties for planting in the cold mountainous area of northern Hebei,the adaptation test of new oat varieties was carried out.The results showed that the highest grain yield and hay yield were Bayan 4,which were 2509.5,30435.0 kg/hm^2,respectively,the disease resistance and lodging resistance were relatively good.The grain yield and hay yield of Baiyan 15 varieties were 1800.0,19051.5 kg/hm^2,respectively,and the growth period was short.The grain yield and hay yield of Jinyan 8 varieties were relatively high,which were 1468.5,19857.0 kg/hm^2,respectively.The hay yield of Bayou 18 varieties was 24613.5 kg/hm^2,second only to Bayan 4.Therefore,Bayan 4,Baiyan 15 and Jinyan 8 can be used as grain-feeding varieties,and Bayan 18 can be popularized as a fine feeding variety in the cold mountain area of northern Hebei province.
