在杉木分布北缘的苏南低山丘陵试验研究表明，利用萌芽杯幼龄速生的阶段优势，能发掘短轮伐小径材的生产潜力。影响萌芽林生长的因素主要有更新林分种源的遗传特性，立地条件，伐桩密度与更新方式。在山洼、山谷阴坡坡脚等优良立地，实施２２５０～２４００株／桩·ｈｍｔ２密度控制，小块状更新，集约肥培管抚，９年生萌芽林蓄积量达１１８．２～１２６．７ｍ２／ｈｍ２，可产出约８５％的小径材．在山坡中下部中等立地条件，实施较高密度（３０００～３３００株／桩·ｈｍ２）控制，窄带状（８～１０ｍ宽）更新，集约管抚，９～１５年生蓄积量达１１１．７～１３９．６ｍ３／ｈｍ２，可产出约４０％的小径材和农用椽材。而在较差岗坡立地，即使采取高密度（４５００株／桩·ｈｍ２：），窄带状荫芽更新与高水平集约管抚，也无生产小径材的可能。
The experimental study on the southern Jiangsu hilly region in the northern margin of the fir distribution shows that the production potential of short-rotation small-diameter timber can be explored by using the stage advantages of young quick-growing young buds. The main factors that affect the growth of sprouted forest are the genetic characteristics of provenances, site conditions, pile density and updating methods. In the mountains, valleys and shady slopes and other fine sites, the implementation of 2250 ~ 2400 plants / pile · hmt2 density control, small updates, intensive fertilizer training tube, 9-year-old sprouting volume reached 118.2 ~ 126.7m2 / hm2 , Can produce about 85% of the small diameter timber. In the middle and lower parts of the hillside, the control of high density (3000 ~ 3300 plants / p · hm2) and the narrow strip (8 ~ 10m wide) were carried out. The intensive storage and management of 9-15 years old reached 111.7 ~ 139 .6 m3 / hm2, can produce about 40% of the small diameter wood and agricultural rafter. In the poor hillside site, there is no possibility of producing small-diameter timber even with high density (4500 plants / pkg · hm 2), narrow-band shade bud renewal and high-level intensive management.
