[Effects of Lime on Seedling Growth,Yield and Volatile Constituents of Atractylodes lancea].

OBJECTIVE: To investigate the effects of different amounts of lime on yield and quality of Atractylodes lancea, and to provide reference for the herb growing site soil improvement and self-poisoning ease. METHODS: Add different gradients of lime, and then measure their growth targets, yield and four kinds of volatile constituents content(hinesol, atractylone, ß-eudesmol and atractylodin). Volatile constituents yield per plant was calculated. RESULTS: Adding 160 g/m2 lime had a significant role in promoting the growth and yield of herb; Adding 80 g/m2 lime was conducive to the volatile constituents production, and adding lime decreased the atractylone and atractylodin content, while increased the hinesol and ß-eudesmol content; Adding 160 g/m2 lime promoted the volatile constituents yield per plant. CONCLUSION: Adding lime plays a role of neutralize soil pH, antibacteria and prevention incognita, and has a certain degree of ease autotoxicity and obstacle,and then promotes the yield and volatile constituents production of Atractylodes lancea.
