在北亚热带苏南低山丘陵研究表明，杉木无性繁殖，萌条扦插成活率北带种源＞南带种源；１～２年生幼株＞４～５年生幼株；秋插＞春插＞夏插；上方芦帘遮荫十薄膜封闭＞上方遮荫（芦帘，林冠）＞全光。自动间歇喷雾装置＋砻糠灰基质，春、夏、秋扦插效果均好，以春插苗生长最佳。７００×１０－６浓度激素处理能促进提早生根，效果为ＡＢＴ＞ＩＢＡ＞ＮＡＡ。且无性苗造林效果好。故大田扦插不宜全光，也不宜夏插。需选用幼龄萌苗的根际萌条，秋季寄插催根或早春扦插，适量激素浸条，并辅以芦帘上方遮荫，塑料薄膜封闭保温等项技术措施，才能获得较高的生根成活率。
Studies in the northern subtropical south hilly region show that the seedling growth of the Chinese fir is mainly from the south of the south belt, ; Shade above the top of the shade shade film closure> shade above (reed, canopy)> all-light. Automatic intermittent spray device + 砻 chaff ash matrix, spring, summer and autumn cuttings are good, the best growth in spring seedlings. The concentration of 700 × 10-6 hormone treatment can promote early rooting, the effect of ABT> IBA> NAA. And no seedlings afforestation effect. Therefore, cuttings should not be all-green field, it is not appropriate summer inserted. Need to choose the young sprout seedlings of rhizosphere, sprouting in autumn or in early spring cuttings, the amount of hormone immersion, and supplemented shade shade above the plastic film insulation and other technical measures in order to get a higher rooting Survival rate.
