摘要
为筛选出适应西昌冬闲田种植的燕麦品种,对3个燕麦品种的产草量、株高、分蘖数及叶茎比等进行了研究.结果表明:OT1352的干草产量最高,为19?612.93kg/hm2,其次是林纳,为17?904.43kg/hm2,分别比OT834的干草产量13?432.63kg/hm2高46.01%和33.29%.OT834的株高最高,为156.43cm,显著高于其他两个品种;三品种的茎粗、叶重、茎重、株重差异不显著;叶片和穗占单株的比例OT834为39.39%,OT1352为47.83%,林纳为44.10%.林纳的粗蛋白含量最高,为8.47%,其次是OT834(为7.91%),分别比OT1352高29.51%和20.95%,林纳和OT834的酸性洗涤纤维、中性洗涤纤维含量低于OT1352,RFV值分别为101.56和94.86,高于OT1352.综合产草量和营养品质得出,适宜在西昌冬闲田种植的燕麦品种为林纳和OT834.
Abstract
In order to select appropriate planting oats varieties in Xichang, we studied the yield, plant height, tiller number and leaf stem ratio of 3 oat varieties. The results showed that OT1352 had the highest hay yield, up to 19612.93kg/hm2. The second was Linus by 17904.43 kg/hm2, increased 46.01% and 33.29% than OT834 (13432.63 kg/hm2). The plant height of OT834 was up to 156.43cm, significantly higher than the other two varieties. There was no significant difference in stem diameter, leaf weight, stem weight and plant weight of three varieties. The proportion of leaf and panicle per plant of OT834 reached 39.39%, OT1352 was up to 47.83%, Linus was up to 44.10%. Linus had the highest crude protein content (8.47%), followed by OT834 (7.91%), 29.51% and 20.95%higher than OT1352 respectively. The acid detergent fiber, neutral detergent fiber of Linus and OT834 were less than OT1352. The RFV values of Linus and OT834 were 101.56 and 94.86, higher than OT1352. Comprehensive forage yield and nutritional quality can come to conclusion that Xichang winter fallow land suitable oats varieties is Linus and OT834.
