摘要
[目的]探索白术化学除蕾方法,确定抑芽丹（芽敌）30.2%水剂在不同时期与不同浓度的抑蕾效果。[方法]用抑芽丹对白术在不同时期与不同浓度进行系统的化学抑蕾效果研究。[结果]喷施抑芽丹完全可代替手工摘蕾,能够达到省工增产增效的目的。药剂浓度越高,抑制白术花蕾开花的效果越明显,施药时期越早对白术花蕾开花的抑制效果越好;药剂浓度、施药时间与植株高度具有相关性,浓度越高植株越矮,施药越迟植株越高;但过早施用和高浓度会造成白术减产。[结论]在白术现蕾期采用50.0~62.5倍的药剂喷施,能达到增产增效的目的。
[Objective] To explore the chemical bud removal method of Atractylodes macrocephala Koidz.,and determine the inhibition effects of 30.2% maleic hydrazide solution with different concentration at different periods.[Method] The chemical bud inhibition effects of maleic hydrazide with different concentrations against Atractylodes macrocephala Koidz.at different growth periods were systematically studied.[Result] The spary of maleic hydrazide could completely replace bud-picking by hand and achieve the purpose of labor-saving,yield-increasing and efficiency-improving.The higher the concentration of maleic hydrazide and the earlier the spraying time,the better the bud inhibition effect;the plant height was related to the maleic hydrazide concentration and the spraying time,the higher the concentration,the shorter the plant;the later the spraying,the higher the plant;too early spraying and high concentration of maleic hydrazide would reduce the yield of Atractylodes macrocephala Koidz..[Conclusion] The spraying of 50.0-62.5 maleic hydrazide during the budding period would increase the yield.
