为探寻适合在红壤侵蚀区应用和推广的杉木经营模式,对红壤侵蚀区的多种杉木营林措施进行了调查和研究。结果表明：采用2.5代杉木苗的试验地较采用普通苗造林的试验地,杉木植株平均树高和平均地径分别增长58.44%和51.75%。采用扩穴连带抚育措施的试验地 NS4较不抚育的试验地 NS2,平均树高和平均地径分别超出19.67%和21.39%；而采用块状抚育较扩穴连带抚育效果更佳,分别超出27.05%和28.32%。追施沼肥的NS6号试验地中,杉木平均树高为2.18 m,平均地径为3.06 cm；追施化肥的 NS5号试验地中,杉木平均树高为1.89 m,平均地径为2.71 cm；种苗选择和抚育措施相同但未进行追肥的 NS3号试验地,苗高只有1.55 m,平均地径仅为2.22 cm。施用沼液肥能更有效地促进杉木的生长。

In order to find a management model of Cunninghamia lanceolata which are suitable in eroded area of red soil,various silvicultural measures on C.lanceolata in red soil erosion area were studied.Result shows that the mean tree height & ground diameter by using the 2.5 generation seedling of C.lanceolata increase by 58.44% &51.75% than that by using normal seedlings in the testing ground.The mean tree height & ground diameter by a-dopting hole-spread with tending measures in the testing ground (NS4)increase by 19.67% and 21.39% than that in the testing ground (NS2)without tending measures.The tree height & ground diameter by adopting block tend-ing exceed 27.05% and 28.32% than that by adopting hole-spread with tending.In the testing ground (NS6)top dressed biogas manure,the mean tree height &ground diameter is 2.18 m and 3.06 cm,respectively.In the testing ground (NS5)top dressed fertilizer,the mean tree height&ground diameter is 1.89 m and 2.71cm,respectively.In the testing ground (NS3)with same seed selection and tending measures,but without dressing ,the seedling height is only 1.55 m,the mean ground diameter is only 2.22 cm.Application of biogas fertilizer can effectively promote the growth of Cunninghamia lanceolata.
