摘　　要：以4个扁桃品种为试材,采用Logistic曲线对其实生苗高与地径生长过程进行拟合,其拟合相关系数均达0.990 0以上,并估测了速生期的2个拐点及其长度。结果表明:扁桃实生苗高、径生长均符合"S"型曲线,年生长可划分为生长初期、速生期、硬化期3个时期。"莎车一号"、"莎车五号"、"莎车九号"、"莎车十八号"4个品种扁桃的地径生长速生期起始时间比苗高生长早12、14、16、12d;地径生长结束时间分别比苗高生长晚2、4、3d;"莎车九号"的径生长结束时间分别比苗高生长早3d;4个品种扁桃的地径生长持续时间均比苗高生长长14、18、13、15d。不同扁桃品种苗高、地径连日生长量曲线均为双峰型。其中,苗高生长高峰分别出现在5月中旬和7月中旬,而地径生长高峰分别出现在7月上旬和8月上旬。Taking 4kinds of Amygdalus communis L.as test materials,used the Logistic curve to fit different varieties of almond seedling height and ground diameter growth process,the fitting correlation coefficient of more than 0.990 0,and estimated the fast-growing period,two turning point and its length.The results showed that Amygdalus communis L.seedling height and ground diameter growth both in line with the‘S＇type curve,years of growth could be divided into initial stage and fast-growing stage,hardening stage three times;SC-1,SC-5,SC-9,SC-18,four varieties of Amygdalus communis L.diameter growth fast growth period starting time earlier than the seedling height growth of 12 d,14d,12 d,16d;SC-1,SC-5,diameter growth over time compared with the seedling height growth of late 2d,4d,3d;SC-9diameter growth over time compared with the seedling height growth as early as 3d;Four varieties of Amygdalus communis L.diameter growth duration was longer than seedling height growth 14 d,18d,13 d,15d;Different almond varieties seedling height,ground diameter growth curves were bimodal type.Among them,seedling height growth peaks appeared in mid May and mid July,the diameter growth peaks appeared in early July and early August.
