马尾松母树林种子产量预测方法的研究

Studies on Prediction Methods of Seed Crop for Masson Pine (Pinus massoniana)

１９９２～１９９４年在福建省清流县灵地马尾松母树林中研究了预测球果和种子产量的可见半面树冠法、信息段法和球果切开法。结果表明，上述方法均能较好地预测马尾松母树林的球果和种子产量，且操作简便、精度高。但由于本文调查对象为结实初期的母树，还需要在推广应用中对拟合方程进一步验证和补充。

A threeyear investigaton has been made to predict cone and seed crop by means of counting number of visible cones in crown from an observation point,counting number of cones in certain informatives section of crown and cone cutting at Qingliu Masson Pine seed production stand.The results show that above methods can easily be and precisely used to predict cone and seed crop of masson pine.
