摘　　要：在对水稻钵体苗的质量、含水率、苗高等基本参数测试分析的基础上,测试研究了水稻钵体苗茎叶拉断力、拔苗力以及秧苗抗折断力,并计算了拉断应力。探讨了拉断力与秧苗横断面、拔苗力与起拔角度的关系。The physical and mechanical properties in addition to the weight, water content and plant height of the pot-grown rice seedlings were measured. The pulling strength of the stem and leaves, the shearing strength of the stem and the picking force were also tested. The pulling stress was calculated. The relations between pulling strength and cross section of the stem, picking force and picking angle were analyzed.

关 键 词：水稻钵体苗 物理参数 拔苗力 拉断力 折断力
