室内石硫合剂对杨柳树花序生长的影响

Effects of Indoor Lime Sulphur on Inflorescence Growth of Poplar and Willow

在杨柳树花序伸长期,室内对雌雄花序喷施不同浓度的石硫合剂,通过测定雌雄花序长度的变化,研究石硫合剂对杨柳树花序生长发育的影响。结果表明,室内喷施不同浓度的石硫合剂对毛白杨雌雄花序生长均有明显的抑制作用;对垂柳花序抑制效果不显著,需重新对垂柳进行试验设计。

During the inflorescence elongation, Effects of lime sulphur on inflorescence growth of poplar and willow were studied by indoor spraying lime sulphur with different concentrations to male and female inflorescence and measuring the changes of the inflorescence length. The results showed that it had obvious inhibition effect on the growth of male and female inflorescence of white poplar; the effect on weeping willow inflorescence was not significant. So a new experiment design is necessary for the weeping willow.
