云南丽江云木香地膜覆盖规范化栽培技术

目的：研究云木香地膜覆盖规范化栽培技术。方法：在云南丽江对云木香地膜覆盖栽培技术多年试验研究的基础上,总结了云木香全生育期地膜覆盖规范化栽培技术措施,同时讨论了丽江地膜覆盖栽培云木香增产的原因。结果：通过地膜覆盖栽培云木香,出苗率可达90％以上,2年生的主根长达20．36—42．71cm;最大根粗达3．37～5．40cm;折干率达31．60％-34．74％;最高产量可达10032kg·hm2;总灰分小于4％,酸不溶灰分小于2％。结论：通过此技术,在生产上可实现云木香的规范化种植,促进丽江及周边地区云木香产业化发展。

Technical Regulation in Saussurea lappa Cultivation by Covering Plastic Mulch in Yunnan Lijiang

Objective：To study technical regulation in Saussurea lappa cultivation by covering plastic mulch in Lijiang. Methods： After many tests were carried out, technical regulation in Saussurea lappa＇ s whole growth period by covered plastic mulch were summarized. The reasons of Saussurea lappa＇ s production increased by covering plastic mulch were also discussed. Results： Through this technique, the percentage of seeding reached more than 90%, the length and diameter of taproot were 20. 36 -42.71 em and 3.37 - 5.40 em respectively, the sulphated ash weight is less than 4% , the acid insoluble ash weight is less than 2% two years later. Conclusion： Normative euhivation of Saussurea lappa in Yunnan can be achieved by this technique, and industrialization development of Saussurea lappa in Yunnan will be promoted in Lijiang and around areas.
