本文作者对我省南部毛白杨雌、雄株在沙地上的生长状况作了一些具体的调查和比较,说明了毛白杨雌株在沙地上较雄株具有一定的生长优势。但从全省来看,雄株远较雌株分布的范围广泛,而且木材材质较雌株紧密、坚实。至于雄株在其他适生的立地条件下,是否低于雌株,尚待进一步调查证明。另外,雌株每年在蒴果成熟期,果絮飞扬,对环境有不利影响,不适于做为城市绿化的树种。 The authors made some specific surveys and comparisons on the growth status of male and female poplar plants in the southern part of our province, which shows that the female plant of Populus tomentosa has some growth advantages on the sandy land. However, from the perspective of the province, male plants are far more widely distributed than female plants, and the wood material is more compact and firm than the female plants. Whether the male plant is lower than the female plant under other suitable habitat conditions remains to be confirmed by further investigation. In addition, the female plant every year in the capsule maturity, Xu Xu flying, have an adverse effect on the environment, not suitable as a green tree species.
