摘要
在甘肃中部半干旱区,对近年来当地种植表现突出的9个马铃薯品种的产量水平、农艺性状、生物量变化及水分利用效率等进行了比较试验。结果表明,土壤含水量随品种生育期变化而变化,与品种特性无关。青薯9号、定薯3号、冀张薯8号、陇薯10号和庄薯4号产量分别为44 727.3、42 666.7、41 515.2、41 060.6、40 121.2 kg/hm^2,居前5位,水分利用效率较高,田间表现较好,适应能力强,建议在当地大面积推广。
In the semi-arid area of central Gansu,9 potato cultivars have been compared with yield,agronomic traits,biomass and water use efficiency,which are prominent in the field of planting in recent years.The result shows that the soil water content varied with the growth period of cultivars,but not related to the cultivar characteristics.The yield of Qingshu 9,Dingshu 3,Jizhangshu 8,Longshu 10,Zhuangshu 4 are 44 727.3,42 666.7,41 515.2,41 060.6,40 121.2 kg/hm^2,ranked in the top 5,the water use efficiency and field performance is good,strong ability to adapt,it is recommended in the local areas.
