摘　　要：不同时间、不同立地条件下的核桃楸花粉密度以及气象因子对花粉密度的影响研究结果表明：散粉盛期为3天,日散粉密度最大值出现在11：00~14：00;园内授粉有效花粉密度不到地面的一半,且分布不均匀,园内花粉流失量大;花粉密度与座果率密切相关。With different time and different site conditions of Juglans mandshurica pollen density and the influence of meteorological factors on pollen density were studied. The results showed that powder stage for3 days, Day powder density maximum value appeared at 11：00 PM, Campus pollination effective pollen density less than half of the ground, and uneven distribution of garden of pollen loss is big. The pollen density and fruit-set rate are closely related.
