苜蓿新品种应用技术及经济效益对比分析

Application of New Alfafa Varieties and Comparative Analysis on Economic Benefits.

对引种苜蓿的生产性能及其经济效益研究结果表明:在试验地条件下,苜蓿品种不同,干草和种子产量及其经济收入也明显不同,多数品种都表现出较高的产量和经济效益。其中,杂种1代、Makiwakaba原种、Baralfa、阿尔冈金、牧歌40Hz、金皇后、杂种4代、甘农3号等8个品种表现出较高的产草量和经济效益;Euver99、Makiwakaba98、Makiwakaba原种、Vertus原种、Euver98、爱菲尼特、甘农3号等7个品种表现出较高的种子产量和经济效益。在水肥条件较好的地块,国外的苜蓿品种产草量较国内的品种高18%～27%。

31 alfalfa cultivars were seeded in the experimental plots at Grassland Management Station, 5km east around Linxi county. The results showed that most of the new cultivars of them introduced performed higher productive ability and higher economic effects. For example, the eight cultivars, including the first generation hybrid, Makiwakaba original, Baralfa, the fourth generation hydrid,Gan-nong,No.3 displayed a higher herbage production and better economic benefits; another seven cultivars, including Euver99、Makivakaba98、Makiwakaba original,Vertus original,Euver98,Gan-nong No.3 performed high seeds production and economic benefits. Further study showed that the herbage yield of the foreign cultivars was more than 18%～27% of the Chinese alfalfa cultivars.
