Abstract：In order to clear the effects of different maize -peanut intercropping modes on system yield and its components and land use efficiency,a two -year field experiment was conducted from 2013 to 2014 in North China.In the experiment,six cropping patterns were designed including maize monoculture,peanut monoculture,maize -peanut intercropping planting with row ratio as 2∶3,2∶4,3∶3 and 3∶4 respectively, and their effects on crop yield,yield components and land equivalent ratio were analyzed.The results showed that the maize yield on net area of intercropping pattern increased significantly with ear number per hectare in-creasing,while the grain number per spike and 100 -grain weight decreased.The intercropping mode of maize and peanut at the ratio of 2∶4 obtained the highest maize ear number per hectare and yield on net area and the intercropping peanut yield,so it was the most conducive to the intercropping peanut yield increase un-der the experimental conditions.The land equivalent ratios of these intercropping modes were all greater than 1,which showed the obvious advantage on yield.The intercropping of maize and peanut at the ratio of 3∶4 ob-tained the highest system yield,which was 8 367.0 kg/hm2 in 2013 and 10 432.5 kg/hm2 in 2014;this inter-cropping pattern had advantages on maize and peanut yield,system yield,land equivalent ratio and the land use efficiency which increased 15% ~21%,so it is the ideal cultivation pattern for stabilizing crop yield and increasing oil production.
