七叶一枝花育苗及林下栽培技术

七叶一枝花通过采用种子冷藏和沙藏后,再经控温催芽的方法,加快种胚的后熟过程,打破种子的休眠,缩短了种子的出苗时间。将已经出苗的七叶一枝花种植于阔叶林、针叶林、灌木林下进行栽培,种植于阔叶林下的七叶一枝花的成活率较高。通过比较可以发现该方法能够扩大生产,节约成本,提高产量,缓解因七叶一枝花市场货源紧缺所产生的供需矛盾,可充分利用林地资源,有效提高林地的利用率。

Research of the cultivation technology and plant technology under forest of Paris polyphylla Smith

Paris polyphylla Smith has been using the storage for seed in refrigeration and sand,then controlling the temperature hastens the process of after-ripening embryo,breaks the seed dormancy,and it will shorts the time of emergence of seed. The emergence of P. polyphylla has been planted in broad-leaf forest,coniferous forest and shrub forest for cultivation,and grown in broad-leaved P. polyphylla Smith has a higher survival rate. Basing the comparation,this method could be expanding production and yield,saving the costs,and alleviate the contradiction of P. polyphylla Smith market supply shortage,it＇s can make full use of forest land resources and improve the utilization of forest.
