由云南省文山州三七研究所主持、云南农业大学协作研究的“三七地膜覆盖栽培研究”课题,于1991年11月30日在昆明通过省科委主持的专家鉴定。该项研究从1986年开始,1989年被列为云南省“七·五”重点攻关课题,历时六年,科研人员根据目前三七栽培中存在的需水需肥多、产量低等问题,将地膜覆盖栽培技术引进到三七栽培上,从育苗、大田移栽、荫棚透光度、水分、肥料等方面进行了较为系统的研究,取得了满意的效果。三七地膜覆盖栽培具有显著的增产效果和明显的经济效益。地膜覆盖栽培产量种苗较对照增产8.82～24％,商品七较对照增 Yunnan Province Wenshan Prefecture Panax Institute, Yunnan Agricultural University collaborative research “Panax film mulching cultivation” project, in November 30, 1991 in Kunming, led by the Provincial Science and Technology Commission identified experts. The study began in 1986 and was listed as a key issue of the “Seventh-Five-Year Plan” in Yunnan Province in 1989. It lasted for six years. According to the current demand for water and fertilizer needed by Panax notoginseng, Film mulching cultivation techniques were introduced into the cultivation of Panax notoginseng, and the systematic researches were made from the aspects of nursery, field transplanting, translucency, moisture content and fertilizers, and achieved satisfactory results. Panax notoginseng mulching has significant yield-increasing effect and obvious economic benefits. Plastic film mulching cultivation yield seedlings 8.82 ~ 24% increase compared with the control, commodity seven increase compared with the control
