Abstract:
‘Guanzhong alfalfa’ was the main alfalfa cultivar variety in Guanzhong Plain,but ‘Guanzhong alfalfa’ had low grass yield and poor grass quality.In order to select high yield alfalfa variety in Guanzhong Plain,taking ‘Guanzhong alfalfa’ as control,the phenological period,plant height,grass yield,dry-fresh ratio and leaf-stem ratio of 10 alfalfa varieties were monitored,including ‘Giant energy 601’ ‘Danon VNS’ ‘Thunderclap’‘Giant moisture tolerance’ ‘Polar bear’ and others.The results showed that different varieties of alfalfa all grew and developed normally in rainy year and irrigated Guanzhong Plain,‘Giant energy 601’ and ‘Danon VNS’ not only had higher grass yields,lower plant height,lower dry-fresh ratio,but also had higher leaf-stem ratio.Guanzhong Plain should take ‘Giant energy 601’ and ‘Dannon VNS’ as the main popularized varieties,and phase out ‘Guanzhong alfalfa’.
