毛白杨在莱西县有悠久的栽培历史,以大小沽河、渚河两岸及中部平原最多。1957年店埠公社前、后庄头等大队开始利用加杨作砧木嫁接毛白杨,除四旁植树和原地定植外,1959年成片栽植了10亩丰产林(株、行距为2×2.5米,每亩133株),据1965年秋调查:生长茂盛,叶大皮光,平均高12.5米,胸径12.5厘米。为了加速毛白杨的繁殖,我们根据几年来的经验,1965年夏、秋两季在全县范围内,开展了一个群众性的芽接毛白杨运动。我们的做法有如下几点: Populus in Lacey County has a long history of cultivation to the size of the river, the Zhu River and the central plains up. In 1957, before the port commune, the first sub-group of Zhuangtou began to use Poplar as a rootstock for grafting Populus tomentosa. In 1959, 10 acres of high-yielding forest were planted in a piece of planted with a row spacing of 2 × 2.5 meters, 133 per acre), according to the survey of autumn 1965: lush growth, large leather leaves, an average height of 12.5 meters, 12.5 cm in diameter. In order to speed up Populus tomentosa breeding, we based on years of experience, the summer of 1965 and autumn in the county-wide, carried out a mass of budding poplar movement. Our approach has the following points:
