目的：为了寻找三七建棚替代材料，以缓解三七生产与林业发展的矛盾。方法：通过田间小区试验及多点试验，从田间小气候，三七生长发育及三七产量等方面，进行遮阳网与传统荫棚的对比试验，用田间统计的方法观察差异性。结果：采用三七专用塑料遮阳网栽培，产量比传统栽培提高１７％，存苗率提高４．５％。出苗率提高１４％。结论：三七专用塑料遮阳网栽培技术是适宜三七主产区的一项新技术，具有明显的经济效益和生态效益，可在生产中推广应用
Objective: In order to find alternative materials for the construction of Panax notoginseng, in order to alleviate the contradiction between the production of Panax notoginseng and the development of forestry. Methods: Field experiments and multi-point experiments were carried out to compare the contrast between shading net and traditional shady canopy from the field microclimate, the growth and development of Panax notoginseng and the yield of Panax notoginseng. The field statistics was used to observe the difference. Results: Panax notoginseng plastic net cultivation, the yield increased 17% than the traditional cultivation, storage seedling rate increased 4.5%. Emergence rate increased by 14%. Conclusion: Panax notoginseng plastic shade net cultivation technology is a new technology suitable for the main producing areas of Panax notoginseng, with obvious economic and ecological benefits, which can be widely applied in production
