摘　　要：采用4因素3水平正交试验,分析不同膜上覆土厚度、密度、品种和膜内包芯方式对闽西山区春种马铃薯产量及经济性状的影响。结果表明,品种对产量起主要作用,其次是膜上覆土厚度和密度,膜内包芯方式对产量的影响最小。试验最优的组合为膜上覆土厚度1~2 cm、密度为60 000株/hm^2、品种为中薯5号、膜内包芯方式为稻草+覆土。L9(3^4)orthogonal test was used to analyze the effects of different film covering soil thickness,density,varieties and intramembrane core-wrapping methods on yield and economic characteristics of spring potato in mountainous areas of western Fujian.The results showed that varieties played a major role in the yield,followed by the film covering soil thickness and density of the overlying soil,and the intramembrane core-wrapping mode had the smallest effect on the yield.The optimum combination was as follows:the film covering soil thickness was 1-2 cm,the density was 60000 plants/hm^2,the variety was Zhongshu 5,and the intramembrane core-wrapping method was straw+mulched soil.
