摘　　要：为了探索兴安落叶松幼林合理间作模式,连续2年对造林当年和第2年的林地进行间作。结果表明:不同模式间兴安落叶松幼林树高和地径生长量差异均极显著,显著水平为0.0001。造林当年,生长量最大的间作模式是间作红小豆,树高和地径生长量分别达到59.49 cm和0.70 cm;造林第2年,生长量最大的间作模式是间作大豆,树高和地径生长量分别达到109.35 cm和1.77 cm。间作后净收入最大的作物是籽角瓜,造林当年为235.19元/667 m2,造林第2年为290.62元/667 m2。In order to explore the reasonable intercropping pattern in young forest of Larix gmelinii Rupr. , the inter- cropping has been carried in afforest first year and the second year for continuous 2 years. The results show that there are significantly differences between the height and ground diameter of young forest of Larix gmelinii Rupr. with different intercropping patterns, which the significant level is 0. 0001. In afforest first year, the intercropping pattern with the maximum growth is red bean, which the tree height and ground diameter are 59. 49 cm and 0. 70 cm separately. In the second year, the intercropping pattern with the maximum growth is soybean, which the tree height and ground diameter are 109.35 cm and 1.77 cm separately. The highest net income of intercropping pattern is pumpkin, with 235.19 Yuan/667 m^2 for the first year and 290. 62 Yuan/667 m^2 for the second year.
