摘　　要：【目的】寻找适宜核桃振动采收装置的技术参数,对新新2、扎343、实生核桃三个品种的果柄分离力和影响因素进行测试与研究。【方法】以核桃的青皮硬度、果皮开裂度作为影响果柄分离力的主要因素进行测试,分析各因素与果柄分离力的皮尔森相关系数。【结果】由相关性检验可知,在0.01水平下3个品种果实青皮硬度与果柄分离力正相关,青皮开裂度与果柄分离力负相关。【结论】曲线拟合结果中,开裂度对果柄分离力的影响,扎343欠佳;青皮硬度对果柄分离力的影响,实生核桃欠佳,其他拟合度均较高。[Objective] In order to find suitable technical parameters for walnut vibration harvesting device,this project aims to test and research the peduncle separation force and influence factors of walnut Xinxin 2 and Zha 343.[Method] The walnut peel cracking-splitting degree and peel hardness were taken as the main factors affecting peduncle separation force to analyze the factors and peduncle separation force of Pearson correlation coefficient.[Result] The correlation test showed that at the 0.01 level,peel cracking-splitting degree and peel hardness had significant influence on fruit peduncle separation force.The peel hardness was positively related to peduncle separation force,and the peel cracking-splitting degree was negatively correlated with peduncle separation force.[Conclusion] Observing curve fitting results,the cracking-splitting degrees had influence on peduncle separation force.The walnut Zha 343 was not good enough.The peel hardness had effect on peduncle separation force,but seedling walnut was not ideal enough.Fitting degrees of other walnuts were all higher.
