摘要
2010-2011年,在山西省大同盆地中度苏打盐碱地对来自国内外的金皇后、三得利、农宝等18个紫花苜蓿品种进行了品比试验,对各品种的发芽率、出苗率、鲜草产量进行了比较,测定了2011年的牧草干鲜比并对干草产量进行了对比分析。结果表明,金皇后、德宝和三得利3个苜蓿品种在中度盐碱地有较强的耐寒、耐盐碱特性和明显的高产优势。建议在大同盆地和其它同类型轻度-中度盐碱地大力推广金皇后、德宝和三得利,提高种植效益。
From 2010 to 2011, a variety test on 18 domestic and overseas alfalfa varieties such as Golden Queen, Three Profits and Farmers was conducted on the moderate saline-alkali land in Datong Basin. The germination rate, emergence rate and fresh forage yield of various varieties were compared. The dry weight/fresh weight ratio of forage for each variety was determined in 2011, and a comparative analysis was conducted to the dry forage yields of the varieties. The results showed that Golden Queen, Three Profits and Farmers had good adaptability for cold and salinity resistance and obvious yield-improving strength in moderate saline-alkali soil. Therefore we suggest that Golden Queen, Three Profits and Farmers be wildly promoted in mild to moderate saline-alkali soil in Datong Basin and other areas, so as to raise the effectiveness of cultivation.
