五针松(Pinus parviflora)原产日本,姿态苍劲,叶色浓绿,四季常青,是我国人民喜爱的盆栽观赏植物,长期以来,多用我国沿海各省广泛栽培的日本黑松(Pinus thunbergii)作五针松砧木嫁接育苗。为寻找到新的砧木,我们选用原产于美国东南部、古巴等地的火炬松(P.ta-eda)、湿地松(Pinus elliottii)、短叶松(P.echinata)作砧,这三种松树在我国江南各省已广泛引种,种源方便。根据松属植物愈合能力弱、愈合过程长,接后需要砧木根系及地上枝促进五针松生长成活的特点,我们用腹接法进行嫁接,接穗和嫁接部位用薄膜套袋保持接穗周围有较高的湿度。嫁接是在1983年10月下旬至 Pinus parviflora native to Japan, vigorous, dark green leaves, evergreen, is our favorite potted ornamental plants, long been widely used in our coastal provinces of Japan Pinus thunbergii (Pinus thunbergii) Five needles pine seedlings grafted seedlings. In order to find new rootstocks, we use P.ta-eda, Pinus elliottii and P.echinata, which originated in the southeastern United States and Cuba, Pines in China’s southern provinces have been widely introduced species, convenient source. According to Pinus plant healing ability is weak, the healing process is long, and then need rootstocks and shoots to promote the growth of Pinus pentaphylla survival characteristics, we use the grafting method of grafting, scion and graft sites with thin film bagging to keep the scion around more High humidity. Grafting was in late October 1983
