摘要
目的:研究腐殖质土添加不同腐熟程度杉木屑对金线莲生长与活性成分的影响.方法:以金线莲组培苗为材料,设置100%腐殖质土(处理A)、40%腐熟杉木屑 + 60%腐殖质土(处理B)、40%未腐熟杉木屑 + 60%腐殖质土(处理C)3个处理,测定金线莲生长指标以及活性成分含量,分析腐殖质土中添加不同腐熟程度杉木屑对杉木下仿野生栽培金线莲生长及活性成分的影响.结果:种植在处理B中的金线莲幼苗保存率最高,达到了84.80%;幼苗茎粗、叶片数、叶片长、叶片宽、根长的增长量均高于其余2个处理;总黄酮与生物碱含量分别比处理A与处理C高出1.17%、25.63%和3.55%、11.34%.结论:腐殖质土中添加杉木屑可提高金线莲保存率,促进金线莲生长,其中60%腐殖土 + 40%腐熟杉木屑栽培效果最佳,值得进一步推广.
Abstract
Objective:To study the effect of adding different degrees of maturity of Chinese fir sawdust to humus soil on the growth indices and active substances of Anoectochilus roxburghii.Methods:A.roxburghii was employed as the experimental material,and three treatments were established:100%humus soil beneath the forest(treatment A),40%mature fir sawdust + 60%undergrowth humus soil(treatment B),and 40%immature fir sawdust + 60%undergrowth humus soil(treatment C).Results:The highest survival rate of the A.roxburghii seedings in treatment B was 84.8%.The growth incre-ments of stem diameter,blade number,blade length,blade width,and root length surpassed the other two treatments.Flavone and alkaloid contents in A.roxburghii were 1.17%and 25.63%higher than treatment A,and 3.55%and 11.34%higher than treatment C.Conclusion:A.roxburghii growth was en-hanced by the combination of humus soil from beneath the forest with fir sawdust,with the most favor-able cultivation effect observed in treatment B(40%mature fir sawdust + 60%undergrowth humus soil),which was deemed worthy of further promotion.
