珍稀药用植物黑蒴育苗试验

Seed Propagation of Rare Medicinal Plant Melasma arvense

[目的]研究黑蒴育苗方法。[方法]应用正交试验设计的方法,从播种基质、水分、播种深度和种子处理4个因素出发,探讨对黑蒴出苗率的影响。[结果]种子处理对播种育苗试验结果的影响最大,其次是播种深度影响较大,其余2个因素对播种育苗存在一定的影响,但差异性均较小;通过试验结果分析选择出最佳的播种育苗方案为:以珍珠岩与红壤土作为栽培基质,3 d浇一次水,播种深度0.3 cm,种子用自来水浸泡24 h后进行播种最好。[结论]该研究为黑蒴的育苗提供理论依据和技术支持。

[Objective] The research aimed to study the method of seedling cultivation of Melasma arvense .[Method] The orthogonal test design method was applied to explore the influence of four factors, namely, sowing media, water content, depth of seeding and seed treatment on the emergence rate of Melasma arvense seedlings.[Result] Seed treatment had the most significant effect on the seedling cultivation followed by depth of seedling. The differences of other factors were insignificant. Through an analysis of the experiment results, the optimal program for sowing and seedling cultivation was selected and shown as follows: taking perlite and red soils as the cultivation medium, water the seed covered with 0.3 cm-thick sand every three days, and the optimal timing to sow the seed was 24 hours after it was soaked in tap water.[Conclusion] This study provides theoretical basis and technical support for seedling of Melasma arvense .
