5个饲用燕麦品种在乌兰察布不同地区的品质性状比较分析

Comparative analysis of quality characters of five forage oat varieties in different areas of Ulanqab

为了明确适宜乌兰察布市3个不同地区种植的饲用燕麦品种,试验采用灰色关联度法对5个饲用燕麦品种的农艺性状和营养品质进行综合评价,同时分析地区和品种对饲用燕麦品质的影响。结果表明:在兴和县,甜燕1号综合性状表现最好;在丰镇市和察哈尔右翼前旗,牧乐思综合性状表现最好;牧乐思在察哈尔右翼前旗鲜草产量达39 530.00 kg/hm2,CP含量为12.88%,均为3个地区的最高值;地区和品种的交互作用对饲用燕麦的株高、鲜草产量、茎叶比、单株分蘖数、主穗长、干物质(DM)、粗灰分(Ash)、粗蛋白(CP)、酸性洗涤纤维(ADF)均有极显著影响(P<0.01),对NDF有显著影响(P<0.05),对粗脂肪(EE)含量没有显著影响(P>0.05)。说明不同品种饲用燕麦的适宜种植区是有限的,察哈尔右翼前旗最适宜种植饲用燕麦,牧乐思和甜燕1号适宜在乌兰察布地区种植。

In order to make clear the suitable forage oat varieties and areas for cultivation in three different regions of Ulanqab, the agronomic traits and nutritional quality of 5 forage oat varieties were comprehensively evaluated by the grey correlation degree method in this study, and the influence of region and variety on the quality of forage oat was analyzed. The results showed that the comprehensive traits of Tianyan No. 1 in Xinghe County had the best performance. In Fengzhen and Chayouqianqi Banner, the comprehensive character of Molasses was the best. The fresh grass yield of Molasses in Chayouqianqi Banner reached 39 530.00 kg/hm2, and the CP content was 12.88%, which were the highest in the three regions. The interaction of regions and varieties had the most significant effects(P<0.01)on plant height, fresh grass yield, stem-leaf ratio, tiller number, panicle length, DM, Ash, CP, ADF, had a significant effect(P<0.05)on NDF, and had no significant effect(P>0.05)on EE content. The results indicated that the suitable planting area of different forage oat varieties was limited, Chayouqianqi Banner was the best region to grow forage oat, Molasses and Tianyan No.1 were suitable for cultivation in Ulanqab.
