摘要
通过对青栲的育苗、造林试验,结果表明:采用种子随采随播育苗,1年生苗木高生长达49 cm,地径达0.75 cm;幼苗的年生长节律明显,高、径生长的高峰期分别在7—11月、8—11月,5年生青栲幼林平均树高达2.5 m、平均胸径2 cm,其生长量低于同龄木荷幼林。在2008年雨雪冰冻灾中,青栲纯林受损指数低于木荷、红楠纯林;在柳杉+青栲异龄混交林中,青栲个体的受损低于纯林。
Our seedling raising and afforestation studies showed that 1 year-old seedlings of Cyclobalanopsis myrsinaefolia had 49 cm of stand height and 0.75 cm of basal diameter. These seedlings had a distinct growth rhythm： July to November was a period of high growth rate of height and diameter. 5-year-old young forest had 2.5 m of height and 2 cm of average DBH, and their mass growth was lower than young stand Schima superba forests at the same age. With suffering the snow-frost damage in 2008, damage indexes of pure Cyclobalanopsis myrsinaefolia forests were lower than Schima superba forests and Machilus thunbergii forests; while damage of, non-even aged mixed forests Cyclobalanopsis myrsinaefolia was much lower than that of pure forests.
