21个紫花苜蓿品种的生产性能和营养价值比较研究
Comparative Study on Production Performance and Nutritional Value of 21 Alfalfa Varieties
摘要
Abstract
[Objective]This study aims to evaluate the production performance and nutritional value of 21 alfalfa(Medicago sativa)cultivars in the Aohan Region of Chifeng,Inner Mongolia,to identify high-yield and high-quality cultivars suitable for local cultivation,to provide a scientific basis for the development of the regional forage industry.[Methods]A three-year field trial was conducted to assess the production performance indicators of 21 alfalfa cultivars,including overwintering survival rate,plant height,fresh forage yield,hay yield,and fresh-to-dry ratio.The nutritional indicators such as crude protein content,crude protein yield,crude fat content,ash content,acid detergent fiber content,neutral detergent fiber content,and relative feed value were also measured and compared.The comprehensive performance of different cultivars was analyzed,and classification was conducted accordingly.[Results]In terms of production performance,Longmu 803 exhibited the highest average annual overwintering survival rate(98.83%),while WL440 had the lowest(74.00%).WL363HQ had the tallest average annual plant height(189.99 cm),whereas WL319HQ was the shortest(163.43 cm).4020MF produced the highest average annual fresh forage yield(52.17 t·hm⁻²),while AC Caribou had the lowest(34.14 t·hm⁻²).Xinmu No.4 and 4020MF had the highest average annual hay yield(14.34 t·hm⁻² and 14.32 t·hm⁻²,respectively),while AC Caribou had the lowest(9.96 t·hm⁻²).WL326 exhibited the highest fresh-to-dry ratio(3.57),whereas WL354HQ had the lowest(3.22).Regarding nutritional value,Longmu 803 had the highest crude protein content(23.03%),while WL363HQ had the lowest(20.78%).Xinmu No.4 had the highest crude protein yield(3.27 t·hm⁻²),while AC Caribou had the lowest(2.25 t·hm⁻²).Longmu 806,WL326,and Magnum Ⅱ exhibited the highest crude fat content(1.72%),whereas WL440 had the lowest(1.55%).WL298 had the highest ash content(10.59%),while Gongnong No.1(9.59%)and AC Caribou(9.54%)had the lowest.The annual variations significantly affected multiple traits,and the performance trends of different cultivars varied across years.Based on an analysis of 12 phenotypic traits,the 21 cultivars were classified into three categories:high-yield and high-quality,medium-yield and low-quality,and low-yield and medium-quality varieties.[Conclusion]Considering both production performance and nutritional value,Xinmu No.4 and 4020MF demonstrated the best overall performance,exhibiting both high yield and high quality.These cultivars are recommended for promotion in the Aohan Region to enhance local forage production efficiency and feed supply capacity.关键词
