烯效唑对柑橘秋梢生长发育的影响

摘要

Objective] The aim was to study effects of uiniconazole on growth and development of autumn shoots of citrus.[Method] With citrus variety "Dafen"in Suzhou region as test material, spraying different concentrations of uiniconazole suspending agent, effects of uinicon-azole on shoot number, shoot length, stem diameter, leaf number and spacing were studied.[Result] The result showed that different concen-tration of uiniconazole could inhibit the growth of shoot number, shoot length, stem diameter, leaf number, and leaf spacing, the effect of 750 times 10% uiniconazole suspending agent was most significant.[Conclusion] The study can provide a certain theoretical basis for drug control of fruit tree shoots.%[目的]研究烯效唑对柑橘秋梢生长发育的影响。[方法]以苏州地区柑橘品种“大分”为试验材料，采用不同浓度的烯效唑悬浮剂对其进行喷施处理，研究烯效唑对柑橘抽梢数、梢长、茎粗、叶片数和叶间距的影响。[结果]不同浓度的烯效唑悬浮液处理均能抑制柑橘幼树的秋梢数、梢长、茎粗、叶片数和叶间距的生长，且浓度越高效果越明显，以750倍液10％烯效唑悬浮剂处理的效果最显著。[结论]该研究可为果树的枝梢药物调控提供一定的理论依据。
