摘要
本文用可见半面树冠法、信息段法对福建省洋口林场、尤溪经营林场杉木一代种子园花期、果期预测球果产量进行初步的研究,结果表明:可见半面树冠球果估测法工作量小,精度较高,至少可提前3个月预测杉木的结实量。此法再进一步完善和补充,可在杉木种子园中全面推广应用。
The results indicate that the work amnunt of the vislhle half-sided crown cone estimation method is small,its precision is relatively high and the bearing amount of Cuninghamia lanceolata can be predicted threemonths ahead of time at least with this method.
