湖北天麻GAP基地不同品种天麻最佳采收期研究

Study on the Optimum Harvest Period of Different Varieties Gastrodiae elata Bl.GAP Cultivation Habitat in Hubei Province

摘要: 对湖北两个天麻GAP(good agricultural practice)基地不同品种的天麻进行了天麻素含量的动态检测和生态条件及产量的考察。结果表明,天麻在5~9月份生长迅速,从10月下旬开始逐渐停止生长,进入11月份天麻产量达到最大;采用RP-HPLC法测定,11~12月份采收的样本天麻素含量最高。据此,确定了湖北GAP基地天麻的最佳采收期:兴山基地的乌天麻、红乌天麻和乌红天麻,广水基地的红天麻均以11月份采收为宜;兴山基地的红天麻以12月份采收为宜。

Abstract: By reversed-phase HPLC to determine the content of gastrodin in different varieties Gastrodiae elata collected with different dates from Hubei GAP cultivation habitat,and at the same investigating the ecological condition and yields.The results indicated that G.elata grew fast from May to Sep.,in Nov.it nearly stop growing and the yield was heaviest,and the peak of gastrodin was in Nov.or Dec.So the optimum harvest period of black G.elata,red black G.elata,black red G.elata from Xingshan and red G.elata from Guangshui were in Nov.,and red G.elata from Xingshan was in Dec.
