实施庭院栽培法能在不增加能耗的条件下，把苗床土壤温度降低2．7～3℃，同时由于遮光和空气相对温度的增加，致使贝母引种栽培可以扩大到某些非适生区。使用此方法，秦贝母由原产地降低海拔1200m，在陕西省凤县首次引种栽培成功并获得高产。

Cultivation of wild Fritillaria glabra can be easily achieved without extra energy consumption simply by shading the seedbed from light to lower 2.7 to 3℃ C of bed temperature with concomitant increase of relative humidity. By so doing, ciltivation can be carried out on ground 1200m lower sea level than its native habitat. Successfal cultivation of F.glabra in Feng county, Shaxi Province, resulted in excellent thigh yield.
