Effect of the Root Outside Fertilization on Yield of Aucklandia lappa Decne

为探索提高云木香产量的根外施肥技术,在云木香植株生长盛期喷施施收多和金刚两种丰产剂,5月和7月各喷施1次,清水作对照,比较施用效果。结果表明以喷施金刚(B处理)的产量最高,每公顷产干品10473.77kg,较施收多(A处理)的增产9.13%,较清水(CK)增产20.11%。合理施用叶面肥,可改善云木香的生长状况,能大幅度促进增产,提高经济效益,该技术可在生产中推广。

To explore the root outside fertilization technique who can increase the yield of Aucklandia lappa Decne. , we sprayed facilities using Shouduo （ treatment A） , Jinggang （ treatment B） and Qingshui （CK） in May and July. The results showed that the effect of treatment B was the best. Next is treatment A. And CK was the worst. The yield with treatment B had raised 9. 13% and 21.11% ,respectively,compared with that of treatment A and CK. The rational application of foliar fertilizer could increase the plant growth, increase the yield and economic benefit. This method is simple and has reference value for the cultivation of Aucklandia lappa Decne..
