摘 要: 通过黑加仑基本物理力学特性的测试与分析,得到了布劳德杂交X14-1和东农大粒两个品种黑加仑果粒直径的分布范围分别为(11.1±3.18)、(11.7±3.54)mm,质量的分布范围分别为(0.87±0.72)、(1.0±0.9)g,密度的分布范围分别为(1.16±0.14)、(1.13±0.12)g·cm-3;黑加仑果实与果柄结合部位的抗拉强度、浆果名义抗压极限和刚度等力学特性指标随成熟度和采收日期的变化规律。为黑加仑采收机械系统的研制提供了设计依据。 The basic physical and mechanical properties were measured and analyzed. The results showed that the distributions of diameters of Brodtorp and Dongnongdali were (11.1±3.18) and (11.7±3.54) mm, the dis- tributions of qualities were (0.87±0.72) and (1.0±0.9) g, the distributions of density were (1.16±0.14) and (1.13±0,12) g·cm-3. The law of the tensile strength, berry nominal counterpressure limit and rigidity and other physical property indexes of the link part of the fruit and its stem changed with the mature degree and the harvesting date was obtained. It offers the basic information for developing the blackcurrants' harvesting machinery system.
