桩坯是盆景生产的物质基础,桩坯养护是盆景生产的关键。桩坯养护成活率的高低,既关系到树木资源的保护和浪费,又关系到盆景生产成本的高低,令盆景工作者十分关心,许多盆景专业户更是如此。近年来,笔者对我院采集的对节白蜡、三角枫、火棘、椎木、水杉、金弹子等十多个树种,一千多个树桩,作了常规养护与全光喷雾养护比较。结果常规养护成活率为59％,其中对节白蜡成活率在70％左右,火棘为50％左右。93年—94年采用全光喷雾养护,成 Pile billet is the material basis for the production of bonsai, pile billet conservation is the key to the production. Pile billet survival rate of conservation, both related to the protection and waste of tree resources, but also related to the level of production costs of bonsai, bonsai workers are very concerned about, many bonsai specialized households even more so. In recent years, I collected more than a dozen trees, more than a thousand stumps, such as white wax, triangular maple, pyracantha, vertebrate wood, metasequoia and gold marbles in our hospital. The results of routine conservation survival rate of 59%, of which section of white wax survival rate of about 70%, about 50% of Pyracantha. 93 - 94 all-optical spray curing, into
