不同栽培方式对金线莲生长状况和品质的影响

金线莲是一种名贵的中草药，人工栽培具有较大经济效益，为探索提高金线莲产量和品质的栽培方式， 设置了2种大棚栽培方式和4种林下栽培方式对金线莲成活率、生长量及总黄酮和多糖含量影响进行研究。结果表明，大棚栽培（T5和T6）的金线莲成活率（分别为92.33%和90.79%）和植株鲜重产量（分别为1.33 g和1.31 g）较高，但其总黄酮含量（分别为11.23 mg/g和12.06 mg/g）和多糖含量（分别为76.97 mg/g和80.43 mg/g）低于林下栽培的。在4种林下栽培方式中，使用控根容器栽培金线莲（T1）成活率较高，达到89.00%，并且其根系生长最好（根数达3.88条，根长达51.40 mm）；但是地面栽培方式可以获得最高的植株折干率，地面栽培（T4）的折干率最高，达到12.12%，其次是T3，其折干率为12.04%。上述结果为金线莲的栽培方式选择提供良好的技术方案。

Effects of Different Cultivation Methods on the Growth and Quality of Anoectochilus roxburghii

Anoectochilus roxburghii is a kind of valuable Chinese herbal medicine, it can gain good economic effect by artificial cultivation. In order to improve the yield and quality of A. roxburghii, a series of experiments were carried out to study the effects of different cultivation methods on the survival rate, growth, yield and contents of active components of A. roburghii. The results showed that, the cultivation in greenhouse（T5 and T6）obtained the higher survival rate(92.33% and 90.79%, respectively) and plant fresh weight(1.33 g and 1.31 g, respectively), but the contents of flavonoids(11.23 mg/g and 12.06 mg/g, respectively) and polysaccharide(76.97 mg/g and 80.43 mg/g, respectively) were lower than the cultivation under forests. In four forests cultivations, using the control container obtained highest survival rate with 89.00%, and roots grew best, the number of root was 3.88 and the lengh of root was 51.40 mm, but the ground cultivation obtained the highest plant drying rate of A. roxburghii, the drying rate of T4 and T3 were 12.12 % and 12.04 %. The findings of the study provided a good technical solution for the cultivation of A.roxburghii.
