Objective] To study effects of different harvest time on the quality of Juglans sigillata from Yangbi, in order to provide the techni-cal basis for the determination of the best harvest time.[Method] With Juglans sigillata as test material, samples were collected on Aug.20, Aug.30, Sep.4, Sep.9, Sep.14 in 2013 and 2014.Before each sampling, with fruit surface having obvious small cracks as the standard, the proportion of fruit peel cracking was observed, the main economic traits of the sample were determined and analyzed.[Result] The results showed that during ripening, with the increase of the proportion of fruit green husk surface having obvious cracks, the average quality of dried fruit and kernel are increased.When the whole tree fruit peel cracking ratio reached 50.00%, the average quality of dry fruit and kernel rate had almost no change, crude fat content and protein content changed little.[Conclusion] When the whole fruit peel cracking ratio about 50. 00% is the optimal harvest time of Juglans sigillata.%[目的]研究不同采收期对漾濞泡核桃品质的影响，为确定漾濞泡核桃的最佳采收期提供依据。[方法]以漾濞泡核桃为试验材料，分别于2013年和2014年8月20日、8月30日、9月4日、9月9日、9月14日进行采样，每次采样前以果实青皮表面具有明显的细小裂痕为标准，观测统计青皮开裂果实的比例，并对样品的主要经济性状进行测定分析。[结果]果实成熟期间，随着全树果实青皮开裂比例的增加，漾濞泡核桃平均干果质量、出仁率都有所增加，当全树果实青皮开裂比例达到50％时，其平均干果质量和出仁率几乎无变化，粗脂肪含量及蛋白质含量变化甚小。[结论]全树果实青皮开裂比例达50％左右时是漾濞泡核桃最适采收期。
