对大小年毛竹林施行单株立竹断鞭(A)、大年春季强度疏笋(B)、改变立竹砍伐期(C)和自然留养小年竹(D,作对照处理)等改制技术措施,经三度(1985～1990年)的试验表明:单项技术处理中以强度疏笋对小年竹的诱发及林分的改制速度作用效果最为明显,较对照处理达到极显著差异,在三度半立竹年龄结构的竹林中小年竹数占立竹总数的42.6％,完成了大小年毛竹林到花年毛竹林的改制。A和B两项措施合并施行(B+A)的改制效果优于A或B,与对照的差异达到极显著水平。其三度半立竹年龄结构的林分中小年竹占49％。断鞭处理在第三度时出现明显的改制效果,与对照相比达到显著差异。改变伐竹期(C)的改制效果与对照处理无显著差异。
The size of the year-old bamboo forest bamboo stand whip (A), the Spring Festival strenghten spring strewing (B), changing bamboo felling period (C) and natural retention of small bamboo (D, as a control treatment) and other restructuring Technical measures, after three degrees (1985 ~ 1990) tests showed that: single technical treatment with strong sparse bamboo shoots of small bamboo and wood conversion rate of the most obvious effect, compared with the control treatment reached a very significant difference in the Three and a half bamboo age structure of bamboo forest middle and small number of bamboo accounts for 42.6% of the total number of bamboo, bamboo completed the size of the year to the annual conversion of Moso bamboo. A and B two measures combined implementation (B + A) restructuring better than A or B, with the control of the difference reached a significant level. The three-year-old bamboo standing structure of middle and small bamboo accounted for 49%. Broken whip processing in the third degree obvious restructuring effect, compared with the control to achieve significant differences. There was no significant difference between the control effect and the control effect when changing the dezhang period (C).
