摘要
通过不同整地方式对杉木生长进程和土壤肥力影响的动态研究,结果表明:整地方式对杉木幼林生长有显著影响,4~14年生影响较大,14年生后生长差别减小以至消失。不同整地方式在整地初期对土壤物理性质的改善作用表现为全垦>带垦>穴垦,整地后一年土壤理化性状指标较整地初期下降,并呈现穴垦>带垦>全垦的态势,至成林阶段土壤肥力受整地方式的影响已不显著。
The dynamic study results of the effects of different site preparation modes on the growth course and soil fertility of Cunninghamia lanceolata the growth of C.lanceolata young forests are significant and the effects at the age of 4-14 are relatively large;the improvement action of different site preparation modes on the soil physical property shows as whole reclamation>band reclamation>hole reclamation in the early days of site preparation;the soil physico-chemical character indexes one year after site preparation reduce as compared with those in the early days of site preparation and assume the state of hole reclamation>band reclamation>whole reclamation;and the effects of site preparation modes on the soil fertility are not significant any longer to the stage of forest establishment.
