摘　　要：通过对沈阳市新民地区杨树与花生、大豆、玉米、西瓜及苗木等作物不同间作模式进行研究及经济效益分析得出沈阳地区杨树林农间作模式中,大行距比小行距经济效益高,因此在沈阳地区,进行速生杨造林时,在满足单株营养面积需求的前提下,尽量选择大行距造林,即4 m×8 m或3 m×10 m株行距。Based on the research and economic benefit analysis of different intercropping patterns of poplar,peanut,soybean,corn,watermelon and seedling in Xinmin area of Shenyang City,it is concluded that the economic benefit of large row spacing is higher than that of small row spacing in poplar agroforestry intercropping pattern in Shenyang area,and“4 m×8 m”or“3 m×10 m”large plant row spacing afforestation is recommended.
