目的:考察人工剪蔓对白条党参药材产量、质量及种子产量的影响,为该药材的资源利用提供参考。方法:以产籽量、药材产量及质控参数为评价指标,在地上茎叶生长旺盛期对白条党参的地上藤蔓实施1次和2次剪蔓打尖,1次剪蔓于7月中旬剪除地上藤茎30cm,2次剪蔓于8月初再次剪除地上藤茎20cm,以自然生长植株作对照,于10月中旬至11月底统一采集种子与药材,测定单位种植面积产籽量、药材产量及质控标准指标参数。结果:1次剪蔓的产籽量高于对照21.4%,2次剪蔓的产籽量低于对照16.5%;1次剪蔓单位面积的药材增产幅度达到25%~35%,且对药材质控参数影响甚微。结论:剪蔓技术能有效调控甘肃党参单位面积的产籽量与产量,生产的党参符合2010年版《中国药典》的质量标准规定,为甘肃白条党参的GAP种植提供参考。
Objective: To investigate the effects of Artemisia sclerotiorum on the yield, quality and seed yield of Codonopsis pilosula, providing references for the resource utilization of this herb. Methods: The seed yield, medicinal material yield and quality control parameters were used as the evaluation indexes. One-time and two-time cut-off manure spikes were performed on the above-ground shoots of Codonopsis pilosula in the vigorous growth of shoots and leaves on the ground. One cut manure was cut off in the middle of July Cane 30cm, 2 cut Manchurian in early August once again cut the ground cane 20cm, with the natural growth of plants as a control, from mid-October to the end of November uniform collection of seeds and herbs, measure the unit acreage of seed yield, yield and quality of medicinal herbs Control standard indicators parameters. Results: The seed yield of one cut manchurian was 21.4% higher than that of the control, and the seed yield of two cut manchurian was lower than that of the control by 16.5%. The yield per unit area of cut manure reached 25% -35% Quality control parameters have little effect. Conclusion: Manchurian technology can effectively control the yield and yield of Codonopsis pilosula per unit area in Gansu province. The produced Codonopsis pilosulae conforms to the quality standard of “Chinese Pharmacopoeia” in the 2010 edition and provides a reference for GAP cultivation of Codonopsis pilosula.
