3个鸡足豆品种在北亚热带地区的适应性评价

Adaptability evaluation of three serradella cultivars in northern subtropical areas

在北亚热带对3个鸡足豆品种的植物学特征和物候期进行了观测,对其草产量、种子产量、抗病性、抗虫性和抗旱性进行了测定和评价。结果表明,3个鸡足豆品种的干物质产量和种子产量较高。其中,皮特曼黄花鸡足豆牧草产量达到6 484 kg/hm2,与当地优良牧草品种相比,略高于云光早光叶紫花苕(P>0.05),显著高于楚雄南苜蓿(P<0.01);马德拉黄花鸡足豆种子产量最高,为1 009 kg/hm2,显著高于其他供试品种(P<0.01)。另外,3个鸡足豆品种的营养价值较高,抗病虫害能力强,中等抗旱,适宜在北亚热带地区生产种植。

Botany characteristic and phenology of three different serradella cultivars （Ornithopus compressus ,Madeira,Pitman and Jebala） were studied through measuring the grass yield, seed yield,disease resistance, insect resistance and drought resistance. The results showed that the dry matter yield and seed yield of three cultivars were high. Among them,compare with the local high quality legume cultivars,the hey yield of Pitman reached 6 484 kg/hm2,higher than Yunguangzao villose vetch（P〉0.05）and higher than Chuxiong burr medic （P〈0.01）. The seed yield of Medeira serradella is the highest （i 009 kg/hm2）,and obvious higher than the other tested cultivars（P〈0. 01）. The results also showed that the nutritive value of three cultivars were high and their ability of diseases and insect resistance and drought resistance was strong. The three cultivars were suitable in the northern subtropical areas.
