摘　　要：通过对正常留种和夏播留种的对比试验,可以获得正常留种和夏播留种的差异性,为当地马铃薯生产提供相关的理论依据。试验结果表明:由于夏播留种生长时间短,它的各项生长指标弱于春播留种是很正常的。但从产量和经济效益分析来看,夏播留种试验是成功的。按当年商品薯地头收购价格计算,夏播留种每667 m2收入为727.5元,比当地农民平均每667 m2毛收入700元多27.5元,说明夏播留种在当地实施是可行的,具有广阔的发展前景。The difference in summer planting seeds and spring planting seeds can be revealed in a comparative experiment in order to provide relevant data for local potato production.Production of potato seed by planting in summer is a measure to avoid the drought and disaster.The growth and yield from seed produced by summer planting were poor due to short growth period of seeds compared with spring planting.However,from the point of view of economic return,seed production by summer planting was successful.The income by growing seed from summer planting was 727.5 Yuan based on local ware potato price,which was higher than that by growing traditional seed from spring planting,700 Yuan,in an area of 667 m2.These data suggested that the seed production by summer planting had bright prospects.
