黄河三角洲中度盐碱地不同燕麦品种生产性能和营养价值的综合评价
Comprehensive evaluation of production performance and nutritional quality of different oat varieties in moderately saline-alkali land of the Yellow River Delta
摘要
Abstract
To select suitable oat varieties in the moderately saline-alkali land of the Yellow River Delta,five oat varieties introduced from abroad,namely'Baler 2','Haymaker','Forage','Challenge'and'Morton',were studied as experimental materials.A completely randomized block design was adopted with three replicates for each variety,totaling of 15 plots.The production performance,agronomic traits,and nutritional quality of each variety were measured.Correlation analysis was conducted among these indicators.Principal component analysis and grey relational analysis were used to comprehensively evaluate the tested oat varieties.The results showed that:1)The fresh yields of'Haymaker'and'Challenger'were 14 700 and 21 133 kg/hm2,hay yields were 4 219 and 5 709 kg/hm2,and plant heights were 67.37 and 70.73 cm,respectively.Meanwhile,leaf proportions of'Forage'and'Haymaker'were 30.65％and 33.31％,and the spike proportions were 32.41％and 35.45％.2)The neutral detergent fiber contents of'Haymaker'and'Forage'were 49.53 and 54.28 g/100 g,respectively,acid detergent fiber contents were 23.61 and 27.23 g/100 g,respectively.The crude protein and total digestible nutrients contents of'Haymaker'were 12.77 and 64.46 g/100 g,respectively,and relative feeding value was 133.35,which were higher than other varieties.3)Correlation analysis showed that fresh yield and hay yield were significantly positively correlated with plant height and stem proportion,while leaf proportion was significantly negatively correlated with hay yield.Dry matter,neutral detergent fiber and acid detergent fiber were significantly negatively correlated with leaf proportion and leaf to stem ratio.Total digestible nutrients and relative feeding value were significantly positively correlated with leaf proportion,leaf to stem ratio,and crude protein,and significantly negatively correlated with dry matter,neutral detergent fiber,and acid detergent fiber.4)The results of principal component analysis and grey relational analysis indicated that'Challenger','Haymaker',and'Morton'ranked as the top three varieties.In conclusion,the production performance,nutritional quality and other indicators of'Challenger'and'Haymaker'outperformed other tested varieties,and the over performance in the moderately saline-alkaline land of the Yellow River Delta is better than that of other varieties,showing great potential for widespread planting.关键词
