三七种子包衣育苗技术研究

目的:研究和筛选适用于三七种子包衣的专用种衣剂产品及配套栽培技术,在三七生产中推广应用。方法:通过室内种子带菌检测、药剂消毒处理效果研究确定3种供试种衣剂配方,并以常规药剂浸种及空白处理为对照,通过田间小区试验比较种衣剂、药-种比和包衣时间对三七出苗率、产量、质量的影响。结果:三七对不同的种衣剂具有明显的适应性差异,种衣剂的使用浓度、包衣时间等因素对三七的出苗率、产量有显著影响。结论:SQ2号种衣剂按照1:50的药、种比,于播种前1～2天包衣处理,能够提高三七种子出苗率和种苗产量。

The Research of Technique of Panax notoginseng Seed Coating for Culturing Seedlings

Objective: To screen seed coating formulation and to investigate culturing seedling technique for Panax notoginseng (Sanqi). Methods: Fungus check for the seeds in room and study on medicament disinfecting effect were carried out to obtain three optimum seed coating fromulation. In contrast with routine medicament immersing seed and blank test, the effects of different seed coating formulation, rate between medicament and seed, and coating time were studied on nursery rate, yield and quality of Sanqi. Results; The different seed coating formulation had evident difference on Sanqi. Concentration of seed coating formulation and coating time notably affected nursery rate and yield of Sanqi . Conclusion: The optimum method is using No. SQ2 seed coation formulation in the rate 1 :50 between medicament and seed, and coated one or two days before sowing.
