针对江苏南部丘陵地区的气候生态特征,开展了引进紫花苜蓿品种的适应性和相关栽培技术研究。结果表明:加拿大品种得龙,美国品种WL320、WL323、金皇后的产量和适应性都显著优于其他品种;丘陵岗坡地种植苜蓿,采用基施纯氮60.0 kg/hm2、硼砂7.5 kg/hm2、钼酸铵300.0 g/hm2、石灰4 500.0~6 000.0 kg/hm2,5%苜豆壮1 200 ml/hm2+苗期用除草剂5%精禾草克900 m l/hm2或秋播种植伴生作物可获得高产。
According to the climatic and ecological characteristics of southern Jiangsu hilly region, the adaptability of introduced alfalfa varieties and related cultivation techniques were studied. The results showed that the yield and adaptability of Canadian variety WL320, WL323 and Golden Queen were significantly better than those of other varieties. Alfalfa was planted in hilly and hillsides with basal nitrogen 60.0 kg / hm2, borax 7.5 kg / hm2, Ammonium molybdate 300.0 g / hm2, lime 4 500.0 ~ 6 000.0 kg / hm2, 5% clove Zhuang 1 200 ml / hm2 + seedling with herbicide 5% fine grass grass 900 ml / hm2 or autumn planting companion crops Get high yield.
