摘　　要：研究影响乌桕结实量的土壤因子、地形地貌因子及不同品种因子,结果显示品种是影响乌桕结实状态的根本性内部因素,优良品种的单株结实量远远大于较差品种;其次是土壤因子和立地条件的影响。运用数理统计分析方法及公式计算其综合效应,制定《信阳乌桕结实量收获评估等级表》,为信阳地区乌桕经济林定向培育提供科学技术支撑。Effects of soil factors, topography factors and varieties on yield of Sapium sebiferum were studied. The results showed that variety was the fundamental influence on fruiting state of S. sebiferum, yield per plant of good varieties was far higher than the poor varieties. Soil factors and site conditions also had effects on fruiting effect of S. sebiferum. This study used mathematical statistics analysis method and formula to calculate the comprehensive effect of above factors, drawn up ＂harvest assessment scale of Xinyang Chinese tallow tree＂, to provide scientific and technological support for the orientation of S. sebiferum economic forest in Xinyang.
