摘要
目的:通过对党参种子基本品质的研究,为企业制定党参生产管理规范提供参考。方法:采用常规方法对山西陵川产党参种子样品进行了初步分级,测定了其大小、净度、千粒重、发芽率等基本品质。结果:党参种子经过筛处理后,初步分为两级,一级种子大小为(1.26～1.48)mm×(0.70～0.78)mm,净率为99.5%,千粒重为334.6mg;二级种子大小为(1.14～1.38)mm×(0.60～0.70)mm,净率为96.1%,千粒重为247.8mg。陈种子的发芽率较低。结论:在党参的规范化生产管理中,必须对种子进行过筛去杂分级,提高净率,即使当年新种子,也要注意种子的储存环境,以保证其含水量,确保种子的发芽率,陈种子忌用。
Objective:By studying the basic quality of the Codonopsis pilosula seed, we can offer reference for the standard management in the production of Codonopsis pilosula.Methods:By the routine method, the Codonopsis pilosula seed samples, which were provided by farmer in Lingchuan county of Shanxi province, were graded first and determined the basic qualities, such as its size, net seed rate, weight of the thousand seeds, germination rate, etc.Results:After sifting the Codonopsis pilosula seed is divided into two grades, the first class size of seed was (1.26～1.48)mm×(0.70～0.78)mm, the net seed rate was 99.5%, the weight of the thousand seeds was 334.6 milligrams; The size of second seed was 11.4～1.38 mm×0.60～0.70 mm; The net seed rate was 96.1%, the weight of the thousand seeds was 247.8 milligrams. The germination rate of old seed was lower.Conclusion:In the standard management of the production of Codonopsis pilosula, we must sift and grade the seed for raising the net seed rate, and pay more attention to the store environment of the new seed for its water content, so ensure the higher germination rate. Don't use the old seed.
