摘要
【目的】为农牧交错带地区(以宁夏盐池县为例)燕麦品种的引进与筛选提供指导。【方法】试验采用随机区组设计,通过对8个不同燕麦品种的株高、茎粗、干鲜比、叶绿素含量、叶面积、鲜干草产量、粗蛋白CP、中性洗涤纤维NDF、酸性洗涤纤维ADF等进行分析,综合评价比较不同品种生产性能。【结果】株高、茎粗、叶宽、叶绿素含量、叶面积、鲜干草产量、CP、粗灰分、NDF、ADF在各品种间差异显著(P<0.05),其中甜燕1号和牧乐思的干草产量较高,分别达到8 670 kg/hm^(2)、7 877.5 kg/hm^(2),较本地燕麦增产分别达到49.4%、42.3%;茎粗分别为4.74 mm和4.53 mm,粗蛋白达到7.83%和7.80%,品质较好。【结论】牧乐思和甜燕1号品种综合表现较好,适宜在当地推广种植。该研究结果可为宁夏盐池地区乃至农牧交错带地区燕麦种植提供科学依据和数据参考。
【Objective】 The study aimed to provide a guidance for the introduction and screening of oat varieties in the agro-pastoral ecotone of Ningxia,with the Yanchi County as a case.【Method】 A randomized block design was used in this experiment,and eight Oat varieties were analyzed by measuring their plant height,stem diameter,dry-fresh ratio,chlorophyll content,leaf area,fresh hay yield,crude protein,neutral detergent fiber and acid detergent fiber,comprehensively evaluating and comparing production performance of different varieties.【Result】 It was showed that there were significant differences in plant height,stem diameter,leaf width,chlorophyll content,leaf area,fresh hay yield,CP,Ash,NDF and ADF among all varieties(P<0.05).Among 8 varieties,Tianyan 1 and Mulesi had much higher yield of the hay,which were 8 670 kg/hm^(2) and 7 877.5 kg/hm^(2) and increased by 49.4% and 42.3%,respectively,compared with local oat.Both varieties had a high quality in that their stem diameter was 4.74 mm and 4.53 mm,and crude protein content was 7.80% and 7.83%,respectively.【Conclusion】 Among 8 varieties,Mulesi and Tianyan 1was better in the comprehensive performance,which was suitable for local planting and extension.The results could serve as basis data and scientific reference for oat planting in Yanchi region and other agropastoral ecotone of Ningxia.
