【摘要】 用同位素32P、15N、86Rb标记技术,证实天麻除必需由蜜环菌获得营养外,还能从土壤养分中得到补充营养,可称为第二营养来源。土壤养分(肥料)可通过蜜环菌或天麻表皮进入天麻体内(参与天麻代谢生理活动),可能影响天麻和蜜环菌的关系和天麻生长,因此研究天麻施肥技术和对产量、质量的影响是很有意义的。更多还原

【Abstract】 Using isotopic labelling technique (with 32P. 15N. 86Rb) , we demonstrated that Gastrodia elata Bl. might draw nutrients from the soil besides their main nutritional source Armillariella mellea (Vahl. ex Fr) Karst. Hence the soil may considered as its second nutritional source.The nutritional components in the soil (fertilizer) are able to enter Gartrodia elata directly or indirectly though the mediation of Armillariella mellea. They may influence the interrelationship between Gastrodia elata and Armillariella mellea, and the growth of the former. Therefore, the study of the influence of fertilization technique on the yield and quality of Gastrodia elata is of significance.更多还原
