基于熵值赋权的DTOPSIS法对鲁南地区11个饲用燕麦品种的综合评价研究

Comprehensive Evaluation of 11 Feed Oat Varieties in Southern Shandong by DTOPSIS Method Based on Entropy Weighting

为筛选适宜在鲁南地区种植的饲用燕麦品种及探讨燕麦新品种综合评价的方法,利用基于熵值赋权的DTOPSIS法对11个燕麦品种的株高、鲜草产量、干草产量、茎叶比、粗蛋白含量、中性洗涤纤维含量、酸性洗涤纤维含量和相对饲草品质等方面进行综合分析。结果表明,熵值赋权法客观评价了各指标在该评价体系中的重要程度,指标中权重最大的是茎叶比,其余依次是鲜草产量、粗脂肪含量、相对饲草品质、干草产量、粗蛋白含量、株高、中性洗涤纤维含量、粗灰分含量和酸性洗涤纤维含量,符合对燕麦饲料的要求。C_(i)值排名前5的品种是燕王、牧王、魄力、贝勒和甜燕麦。这5个品种产量较高,综合性状表现优良,适宜在鲁南地区推广种植。

By DTOPSIS method based on entropy weighting,comprehensive analysis of plant height,fresh grass and hay yield,stem-leaf ratio,crude protein content,neutral detergent fibre content,acid detergent fibre content and relative forage quality was made for screening forage oat varieties in southern Shandong and exploring a new method of comprehensive evaluation of oat varieties.The results showed that the entropy value method could evaluate objectively the importance of indicators in the evaluation system.The index with the largest weight was the stem-leaf ratio,followed by fresh yield,crude fat content,relative quality forage grass,hay yield,crude protein content,plant height,neutral detergent fiber content,crude ash content and acid detergent fiber content,which conformed to the requirements for oats feed.The top five C_(i) values were Forage plus,Haymaker,Charisma,Baler and Sweet oat.The five varieties not only had higher yield,but also had better comprehensive characteristics,and were suitable for planting and popularizing in southern Shandong.
