摘　　要：以马铃薯新品种闽薯1号为试材,应用四因素三水平正交试验方案,研究了播种时间、种薯大小、种植密度和生长调控措施对马铃薯产量和质量的影响。结果表明:在试验设置范围内,对闽薯1号产量影响大小的因素依次为:播种时间﹥种薯大小﹥生长调控措施﹥种植密度,不同因素间存在显著差异。综合评价结果显示,采用播种时间为7月5日、种薯大小为50～79 g、每667m2种植6 500株且花蕾期喷施多效唑的栽培方式种植闽薯1号最适宜,其产量高、质量好且成本较低。Using the perpendicular experiments of four factors and three levels, the research investigated sowing time, size of seed potato, planting density, and growth regulate measures influenees on yield and quality of potato with the potato new variety of Minshu 1. The results showed that factors influencing the yield of seed propagation successively were sowing time, size of the seed potato, growth regulate measures, planting density, according to the seriousness of influence within the experiment＇s design ranges. There was a significant difference of yield with different factors. Further analysis showed： The most suitable time of seed propagation was July 5. The most suitable size of the seed potato was 50-79 g.The most suitable planting density was 6 500 plants in 667 m^2. And the most suitable growth regulate measures was the treatment by spraying the paclobutrazol during the flower bud stage. These factors could bring about high yield, good quality and low costs.
