【摘要】 丝栗栲结实量大小年现象突出,母株上中下层轮盘枝结实量有明显差异。采取施肥,适度疏花,对母树林进行适度疏伐、改善母树中层轮盘枝采光条件等技术措施,能有效调节光照、肥力、开花数量,保持种子产量稳定性,提高母树的结实量和改善种子品质。本文的试验技术数据可为丝栗栲母树林营建及管理提供可靠技术参考。更多还原

【Abstract】 The biennial fruiting of Castanopsis fargesii is quite usual with significant differences in fruit yields among the upper, middle and lower whorled branches of the seed trees. Technical measures could effectively adjust light, soil fertility and number of flowers to keep the seed yield stable and improve fruiting and seed quality of the seed trees which include fertilizing, moderately thinning of flowers and thinning tending of the seed trees to improve light conditions of the middle whorled branches. The test technical data could provide reliable technical reference for establishing and managing Castanopsis fargesii seed tree plantations.更多还原
