杉木种子园球果产量近期预测方法试验初报

A Preliminary Report on the Experiment of the Short-Term Prediction Methods of Cunninghamia lanceolata Seed Orchard Cone Yield

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.
