摘　　要：粗放经营的山杏果实产量株间相差悬殊,传统理论解释乏力。归纳甘肃西峰、天水、定西等市山杏观察案例,分析果实产量株间差异定性资料,指出现象与传统理论的矛盾。利用基于化感作用的生长/生存假说圆满解释了山杏果实产量株间相差悬殊的现象,进而结合生态位构建理论和叶片-未级根共同体理论,提出根系化感塑型假说,阐明了根系的生长机制,进一步提高了理论解释力。The yield of wild Prunus sibirica in extensive management varies greatly among plants,and the traditional theory is weak to explain.The observation cases of Prunus sibirica in Xifeng,Tianshui,Dingxi and other cities in Gansu province were summarized to analyze the qualitative data of fruit yield differences among plants,and to point out the contradiction between phenomenon and traditional theory.The growthsurvival hypothesis based on allelopathy was used to explain the phenomenon of the wide difference in fruit yield among Prunus sibiricaplants.Then,combining the niche construction theory and the leaf-root community theory,the allelopathy modeling hypothesis was proposed to clarify the root growth mechanism and further improve the theoretical interpretation.
