摘　　要：不同间种模式试验结果表明，玉米与大豆间种的土地产出系数达１．１０７～１．５４７，其产值比大豆单种提高５．３％ ～５２．９６％ ，比玉米单种提高２６．８％ ～５６．６８％ ；不同间作模式的粗蛋白总量排序为玉米花生＞ 玉米大豆＞ 玉米红薯，干物质总量排序为玉米红薯＞ 玉米花生＞ 玉米大豆；红壤稻田种植玉米等旱作物后，土壤ｐＨ值呈上升趋势，水解氮呈下降趋势。The results of different intercropping patterns experiment showed that in the intercropping pattern of maize/soybean, the coefficient of land productivity reached to 1.107～1.547, its output value was 5.3%～52.96% more than that in the single cropping of soybean, and was 26.8%～56.68% more than that in the single cropping of maize; Different intercropping patterns were arranged in the following order: maize/peanut>maize/soybean>maize/sweet potato according to total amount of crude protein, and maize/sweet potato>maize/peanut>maize/soybean according to total amount of dry matter; After planting upland crops such as maize and so on in red soil paddy, the pH value of soil showed a rise trend, and available N content showed a fall trend.
