文摘内容 The orthogonal experiment of different factors in 6-year-old poplar stands,including intereropping crops, appli-cation rate of fertilizer, and planting density of forest tree etc., was carried out in the sandland of the Yellow River original course. The results indicated that doing intereropping, enlarging the row spacing and prolonging the time of intereropping were the effective ways by which the needs of forest tree for nutrients could be applied, and the level of forest land produc-tivity could be increased. Meanwhile, the optimum intercropping way of poplar plantations at different ages was gound, which was useful for the site of tne present experiment。
