| 摘 要： | [目的]为杉木人工林的经营管理提供指导。[方法]对3种不同抚育方式(全面铲草、铲草+化学除草、割草+施肥)下杉木幼林的生长量及抚育成本进行比较,确定其最佳抚育方式。[结果]3种抚育方式下,杉木幼林的平均树高分别为3.8、5.0、4.2m,平均胸径分别为5.0、6.4、5.3cm;铲草+化学除草抚育方式杉木幼林的单株材积最高,达0.00970m3,分别为全面铲草和割草+施肥抚育方式杉木幼林单株材积的2.29和1.66倍;割草+施肥抚育方式投资最高(4900元/hm2),其次为全面铲草抚育方式(3600元/hm2),铲草+化学除草抚育方式投资最少(2250元/hm2)。[结论]南方林区杉木幼林的最佳抚育方式为人工除草+化学除草。

| Abstract: | [Objective] The study was to provide the guidance for management of Cunninghamia lanceolata plantation.[Method] The growth increment and tending costs of young C.lanceolata plantation in 3 tending methods(completely weeding,handed weeding+ chemical weeding,mowing+ fertilizing)were compared,and then the optimum tending method was determined.[Result] In 3 tending methods,the average height of young C.lanceolata plantation were 3.8,5.0,4.2 m resp.,and their average dbh were 5.0,6.4,5.3 cm resp..The individual ... |
