中文摘要	在气候变化的背景下,为了探寻陇中黄土高原半干旱区马铃薯的适宜播种期,2010年在甘肃定西进行了马铃薯分期播种试验,并对不同播期条件下马铃薯生长发育及产量形成进行了分析。结果表明:随着播期的推迟,马铃薯全生育期缩短,株高出现明显变化,单株干物质最大积累速率提前;从不同播期来看,5月27日播种的植株高度、叶面积指数、单株干物质积累量和最大积累速率均最大,马铃薯块茎鲜重的增长过程呈"慢-快-慢"S型曲线;块茎鲜重最大积累速率出现的时间随播期的推迟而提前;产量数据的方差和多重比较分析结果表明,播期是影响产量的主要因素,其中5月27日播期的丰产性最好;对各播期不同生育期的气候条件进行比较表明,5月底或6月初是陇中黄土高原半干旱区马铃薯的适宜播种时间。
英文摘要	A field experiment with six sowing dates of potato was conducted in Dingxi of Gansu in 2010,and the growth and yield formation of the potato after sowed at different dates were analyzed,aimed to search for the suitable sowing period of potato in semi-arid area of the loess plateau in central Gansu under the background of climate change.With the delay of sowing dates,the whole growth period of potato shortened,plant height had obvious change,and the dates corresponding to the peak values of dry matter accumulation rate per plant advanced.Among the test sowing dates,the potato sowed on May 27 had the largest plant height,leaf area index,and dry matter accumulation and maximum accumulation rate per plant,and the tuber fresh weight showed an S-variation curve of "slow-fast-slow".The dates corresponding to the peak values of tuber fresh weight accumulation rate were also advanced with the delay of sowing dates.The variance analysis and multiple comparisons of the yield data showed that sowing date was the main factor affecting potato yield which was the highest when the sowing date was May 27.The analysis of the meteorological conditions at different growth stages of potato indicated that the suitable sowing period of potato in semi-arid area of the loess plateau in central Gansu was by the end of May or in early June.
