天麻双扣膜栽培,就是在塑料大棚内的天麻床面上,再覆盖一层塑料薄膜。采用此法栽培天麻无性繁殖比裸地栽培增产23—35％。由于双扣膜有保温、提温作用,到2月份棚内麻床温度即可达10℃以上,天麻便解除休眠开始生长。到10月下旬气温降至10℃以下时,棚内麻床温度仍高于10℃,天麻还可继续生长。这样,双扣膜比裸地可延长冬栽天麻生育时间3个月左右。扣膜可使天麻早栽,密环菌与天麻有充分时间进行结合。待第二年春天麻一萌动即可获得充足的养分,促进子麻的生长发育,为天麻高产打下基础。
Gastrodia double buckle film cultivation, is in the plastic greenhouse Tianma bed, and then covered with a layer of plastic film. This method of cultivation of Gastrodia asexual reproduction than bare cultivation yield 23-35%. As a double button membrane insulation, heating effect, to February shed temperature up to 10 ℃, Tianma will start lifting the dormancy. By the end of October the temperature dropped to below 10 ℃, the studio bed temperature is still higher than 10 ℃, Gastrodia can continue to grow. In this way, the double buckle film can extend the winter planting Tianma fertility than 3 months or so. Buckle membrane can make Tianma early planting, bacteria and gastrodia have sufficient time to combine. To be the second spring Ma Ma move to get enough nutrients to promote the growth of Zi Ma, lay the foundation for high yield Gastrodia.
