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。
Through the dynamic research on the effects of different land preparation methods on the growth of Chinese fir and soil fertility, the results showed that: the site preparation method had a significant impact on the growth of young Chinese fir plantations, with a significant impact from 4 to 14 years of age and the difference of 14 years after birth. In the early stage of soil preparation, the improvement effect of different land preparation methods on soil physical properties showed that all soil reclamation> reclamation> acreage reclamation. Soil physical and chemical properties decreased one year after soil preparation, and presented the situation of reclamation, reclamation and reclamation. Soil fertility by the stage of forest-forming was not significantly affected by site preparation.
