【摘要】 连续3年对不同培育措施的杉木大径材培育效果进行定位监测,对取得的重复测量数据建模进行重复测量方差分析,结果表明:间伐抚育措施对杉木单株立木胸径和蓄积生长有极显著促进作用;施肥措施对单株立木胸径和单株立木蓄积生长有一定的促进作用,但效果未达到显著水平。在杉木大径材培育生产中,应及时实施间伐抚育措施,辅以施肥措施。更多还原

【Abstract】 Through different cultivation measures for large diameter timber of Cunninghamia lanceolata cultivation effect of positioning monitoring for three years in succession, we got plenty of repeated measures data. Then, we conducted analysis of variance for repeated measurement data by making use of the data obtained to build a model. Results showed that the treatments of thinning tending had a significant promoting effect on the growth of stumpage DBH and volume growth for Cunninghamia lanceolata, and fertilization measures as well. To be sure, the latter promoting effect did not reach a significant level. In summary, we can conclude that, in the large-diameter timber cultivation and production of Cunninghamia lanceolata, we should implement thinning measures promptly,supplemented by fertilization.更多还原
