阿鲁科尔沁沙地饲用燕麦品种适应性评价

Adaptability evaluation of forage oat varieties in Ar Horqin Sandland

为筛选出适宜阿鲁科尔沁沙地种植的饲用燕麦(Avena sativa)品种,本研究采用田间随机区组试验设计方法,分别对春播13个和夏播12个供试燕麦品种的株高、旗叶长和宽、第一节茎粗、干草产量及营养品质进行了测定,并采用模糊数学隶属函数法对各指标进行综合分析。结果表明,春播和夏播不同品种燕麦的生产性能及营养品质各指标均存在一定的差异。春播燕麦不同品种隶属函数值由大到小排序为‘福燕1号’>‘贝利’>‘甜燕1号’>‘艾博’>‘悍马’>‘海威’>‘梦龙’>‘速锐’>‘莫妮卡’>‘黑玫克’>‘三星’>‘凯撒’>‘特牧’,夏播燕麦不同品种隶属函数值由大到小排序为‘甜燕3’>‘梦龙’>‘悍马’>‘速锐’>‘甜燕2’>‘甜燕70’>‘海威’>‘艾博’>‘萨摩’>‘楷模’>‘甜燕75’>‘福星’。以上结果表明,适宜在阿鲁科尔沁沙地春播的燕麦品种为‘福燕1号’‘贝利’‘甜燕1号’,夏播的燕麦品种为‘甜燕3’‘梦龙’‘悍马’。

To select special forage oat(Avena sativa)varieties suitable for planting in the Ar Horqin sandland,the plant height,flag leaf length and width,stem diameter,hay yield,and nutritional quality of thirteen spring sowing oat varieties and twelve summer sowing oat varieties were measured using the field randomized block design test method.The fuzzy mathematics membership function method was used to conduct a comprehensive analysis of each index.Results showed certain differences in production performance and nutritional quality indicators between different spring-and summersowing oat varieties.The membership function values of different spring-sowing oat varieties were sorted in the following descending order:‘Fuyan No.1’>‘Beili’>‘Tianyan No.1’>‘Aibo’>‘Hanma’>‘Haiwei’>‘Menglong’>‘Surui’>‘Monica’>‘Heimeike’>‘Sanxing’>‘Kaisa’>‘Temu’.The membership function values of different summer sowing oat varieties are sorted in the following descending order:‘Tianyan No.3’>‘Menglong’>‘Hanma’>‘Surui’>‘Tianyan No.2’>‘Tianyan No.70’>‘Haiwei’>‘Aibo’>‘Samo’>‘Kaimo’>‘Tianyan No.75’>‘Fuxing’.The above results showed that the varieties of oats suitable for spring planting in Ar Horqin sandland were‘Fuyan No.1’,‘Beili’,and‘Tianyan No.1’while the varieties of oats suitable for summer planting in Ar Horqin sandland were‘Tianyan No.3’,‘Menglong’,and‘Hanma’.
