摘要
针叶树球果的物理力学特性是影响针叶树种子采收的重要因素，也是确定采种方式，研究和设计采种机械的重要依据。本文对油松、樟子松球果的基本物理特征、果柄的拉断阻力及果柄的切断阻力进行了试验研究，分析了球果的物理力学特性对采种的影响，并提出了一些建议。
The physical and mechanic properties of coniferous cones are the important factors to affect seed harvesting and the main foundation to determine harvesting method, to study and to design harvesting mechinery. In accordance with the cones of chinese pine and scotch pine in the northern area of China, the paper is dealing with the basic physical characteristics, picking resistance and cutting resistance of cones and their stalk, and with analysis of their impact on seed harvesting. At last, it puts forward some Suggestions.
