摘　　要：优化传统马铃薯—夏蔬菜模式并探索新型种植模式是挖掘辽西地区周年高产潜力,提高资源利用效率的重要途径。以马铃薯—夏花生不同种植模式为研究对象,于2014年在辽宁省绥中进行田间试验,对其周年资源分配、产量及资源利用效率进行了比较。结果表明3种模式协调了两季的积温资源分配比例(0.2∶08和0.25∶0.75;0.32:0.68),3种模式光温分配的变化,引起了相应植株生育性状和产量的变化,3种模式的投入产出比比例为模式Ⅰ0.63∶0.38;模式Ⅱ0.5∶0.49;模式Ⅲ0.37:0.58,模式Ⅰ经济效益最佳,但是投入产出比在3个模式中最大。经济效益的增加主要受马铃薯价格和产量的影响。Optimization of the traditional potato-summer mode and vegetable planting pattern is to explore new mining Bohai annual yield potential,an important way to improve the efficiency of resource use. In this study, potato-summer peanut different cropping patterns for the study, conducted field trials in 2014 in Liaoning Prov-ince Suizhong, compared to its annual allocation of resources, yield and efficiency of resource use. The resultsshow that three modes coordinated two quarters accumulated resource allocation ratio （0.2 ： 08 and 0. 25 ： 0. 75 ;0.32 ： 0.68） ,changes in light and temperature distribution of the three modes, causing a correspondingchange in plant growth and yield traits, the input-output ratio of the proportion of the three modes of mode I 0. 63 ： 0. 38 ; mode II 0. 5 ： 0. 49 ; IDO. 37 mode ： 0.58 , Model I is the best economic benefit, but input-outputratio is the biggest in the three models. The increase of economic benefit is mainly affected by the price and yield of potato.
