摘　　要：通过对无土层河滩地不同整地规格、客土等方法营造杨树丰产林试验，结果表明，在无土河滩地上，当地下水位在1～2．5m时，挖1m×1m×1m大坑整地，客土填抗、深栽、选择耐旱性和抗逆性强的小钻杨，营造的林分能够达到丰产标准。High-yield plantation of poplar were tested on flood land without soil by using different specifications of soil preparation,foreign soil. The result shows that it is need to dig large pit with 1m × 1m × 1m and to fill pit with foreign soil,and to plant deeply on flood land without soil when groundwater level is during 1-2.5m. Populus × xiaozhuanica W. Y. Hsu et Liang whose drought tolerant and stress resistance is strong was selected. Stand can reach standard of high-yield.
