灯盏细辛栽培密度与产量关系研究

目的：通过试验，找出最佳栽培密度，进一步降低成本，提高单位面积产量和经济效益。方法：采用随机区组试验。结果：增加株行距有利于单株或单丛的生长发育；密度越大，单位面积产量越高；在构成产量的三因素中，株距贡献率最大，行距次之，双株略低于行距。栽培管理及育苗成本是株距>双株>行距。结论：最佳密度组合为（20cm×10cm）+双株。

Studies on Effects on Yield of Erigeron breviscapus under Different Cropping Density

Purpose:Through experiment, finding out the best cropping density that reduce cropping cost in order to improve per unit area yield and the economic effect.Method:Adopt the random area group experiment.Result:It is benefit for single plantlet or thicket growing to develop that increase planting space.The cropping density is higher the yield is higher.There are three factors of composing output which are row room, space and single or pair of plants.Among three factors, row room contributes to the most yield, space take the second place, pair of plant contributes less yield than space.The cost of growing seedling and cropping management are composed by three factors:row room > pair of plant > space Conclusion:The best compose of cropping density is 20cm10cm by row room and space with pair plant.
