摘要
在位于临洮县东北部半高寒阴湿山区的上营乡进行5个不同马铃薯品种的种植对比试验.结果表明:‘陇薯5号’‘陇薯6号’‘庄薯3号’‘陇薯7号’对马铃薯晚疫病表现抗病,对照品种‘上梁红花’表现感病;‘陇薯5号’‘陇薯6号’‘庄薯3号’‘陇薯7号’‘上梁红花’的平均产量分别为37 200、33 352、32 550、24 052、23 090kg/hm2,‘陇薯5号’‘陇薯6号’‘庄薯3号’的产量比‘上梁红花’的产量分别高出40.97%、44.44%、61.11%;出苗率、株高、产量、大薯率、大薯质量百分数、畸形薯率、经济系数、根冠比等指示在各品种间差异显著(P<0.05),中薯、中薯质量百分数、小薯、小薯质量百分数、绿薯率、烂薯率、块茎干物质含量等指标在各品种间差异不显著(P>0.05).在临洮县东北部高寒阴湿山区进行高产、高淀粉、大薯形马铃薯栽培以选取‘陇薯5号’‘陇薯6号’‘庄薯3号’较好.
This experiments was supposed to study the tuber yield of 5 potato varieties planted in the high cold overcast and moist mountain area of northeast Lintao county.The result showed that the variety ＇Longshu 5＇＇Longshu 6＇＇Zhuangshu 3＇＇Longshu 7＇ resisted to potato late blight,while the variety ＇Shanglianghonghua＇ was sensitive to it.The tuber yield for ＇Longshu 5＇＇Longshu 6＇＇Zhuangshu 3＇ and ＇Longshu 7＇ was respectively 37 200 kg/hm2,33 352 kg/hm2,32 550 kg/hm2,24 052 kg/hm2,which was respectively higher 40.97%、44.44%、61.11% 4.4%,when compared with ＇Shanglianghonghua＇,which tuber yield was 23 090 kg/hm2.Further more,these characters such as the rate of plantlet emergence,plant height,tuber yield,big tuber number rate,big tuber mass rate economic coefficient and root shoot ratio were deferent among these 5 potato varieties treatments（P0.05）,while these characters such as middle tuber number rate,middle tuber mass rate,small tuber number rate,small tuber mass rate,green tuber rate,blet tuber rate and tuber dry matter content were not deferent among these 5 potato varieties treatments（P0.05）.So these 3 potato varieties such as ＇Longshu 5＇＇Longshu 6＇＇Zhuangshu 3＇ can be popularized for its high starch,big tuber and high tuber yield.
