| 摘 要： | 根据对头状沙拐枣（Calligonum caput-medusae）、泡果沙拐枣（C. junceum）、蒙古沙拐枣（C. mongolicum）、红皮沙拐枣（C. rubicundum）的不同种群生长效益的野外调查结果，对平均地径、新梢长、冠幅（南北、东西）、同化枝节长、灌高6项生长效益指标进行方差分析。 结果表明各种种群间生长效益差异显著，新疆石河子和宁夏沙坡头地区种群的生长效益较好。

| Abstract: | According to the investigation statistics on the 6 growth indexes (mean root-stem diameter, length of annual branch, shrub height, broad of canopy (south-north, east-west), length of two knots of assimilative shoot of Calligonum caput-medusae, C.rubicurdum, C.mongolicum and C.rubicudum, the difference among the population of each species was studied applying the method of variance analysis. The result shows that: the difference are significant, and the growth benefits are better in the populations of Shihezi region of Xinjiang and the Shapotou of Ningxia province. |
