Effects of Forest Stand Types and Fertilizer Types on the Height and Ground Diameter of Polygonatum cyrtonema Hua
Polygonatum cyrtonema Hua is a valuable medicinal herb.This study explores the effects of different forest canopy types and fertilization methods on the growth of Polygonatum cyrtonema Hua to optimize its growth conditions,enhance medicinal yield and quality,and provide scientific guidance for its cultivation.Field experi-ments were conducted in different forest types(including broad-leaved forests,bamboo forests,Cunninghamia lanceolata forests,and pine forests)in Liandu District,Lishui City,Zhejiang Province.The study compared the growth conditions of Polygonatum cyrtonema Hua under different forest environments and investigated the effects of different fertilization methods(organic fertilizer,compound fertilizer,organic+compound fertilizer)in Cun-ninghamia lanceolata forests.Systematic experimental design and data processing methods were employed to quantify the specific effects of different environmental factors and fertilization strategies on the growth indicators of Polygonatum cyrtonema Hua.Results showed that in broad-leaved forest environments,Polygonatum cyrtone-ma Hua exhibited optimal growth performance,with an average plant height of 583 mm,underground tuber weight of 36.2 g,and average leaf count of 12.8.In the fertilization experiment,the combined use of organic and com-pound fertilizers significantly enhanced the growth of Polygonatum cyrtonema Hua,with an average plant height reaching 622 mm,average ground diameter increasing to 2.14 mm,underground tuber weight rising to 35.2 g,and leaf count reaching 12.8.This study revealed that the cultivation strategy combining organic and compound fertil-izers in broad-leaved forest environments effectively enhances the growth performance and medicinal yield of Po-lygonatum cyrtonema Hua.This finding not only enriches our understanding of the growth requirements of Polyg-onatum cyrtonema Hua in the Lishui region but also provides scientific support for optimizing its cultivation tech-niques.
