木醋液对茅苍术生长发育的影响

目的]研究木醋液对茅苍术生长发育的影响。方法]在茅苍术生长发育阶段，经叶面喷施和灌根方式给予4种不同浓度的木醋液，调查茅苍术的各种生物学性状和产量性状。结果]叶面喷施和灌根方式给予木醋液都能促进茅苍术生长发育，根茎产量分别提高60．33％和75．05％；叶面喷施的木醋液适宜浓度为200倍，灌根处理的木醋液适宜浓度为500倍。结论]木醋液能促进茅苍术的生长发育，以灌根方式的效果最佳。

Application of Wood Vinegar in Atractylodes lancea Growth

Objective ] To study the effects of wood vinegar on the growth of Atractylodes lancea. Method ] In the growth stage of A. lancea, treated by foliar spraying and root irrigation ways with 4 different concentrations of wood vinegar, the biology traits and rhizome yield of A. lan- cea, were investigated. Result] Foliar spraying and irrigation treatments of wood vinegar promoted the growth of A. lancea, and improved 60.33% and 75.05% of the rhizome yield. The suitable concentration of wood vinegar foliar spraying is 200 times. The suitable concentration of wood vinegar irrigation treatments is 500 times. Conclusion] Wood vinegar could promote the. growth and development of A. lancea, the effect of irrigation treatment is better.
