Abstract: Researched the mixed sowing populations' yield and yield components in order to improve maize yield and land use capability through the corn 'Zhengdan 958' and semicultivated soybean mixed sowing by 1:1, 1:2, 1:3 mixture ratios, and let the maize monoculture as control. The results showed that, corn production accounts for more than 90% of the population yield; corn production declined slightly, the stem and leaf yield decreased obviously, and semicultivated soybean yield increased with proportions increasing. Groups of mixed biomass yield on the ground and economic yield increased with proportions increasing, and all the mixed sowing treatments were significantly higher than that of maize monoculture, where mixed biomass yield on the ground of 1:3 (A1B3) and 1:2 (A1B2) increased 15.5%, 16.4%than monoculture maize yield.
