摘要
【目的】药用植物施肥措施的研究对于提高药材产量、保证药材品质均具有重要的意义。【方法】采用林下随机区组试验设计,测定施用磷肥和复合肥对云黄连生长性状指标、产量和品质的影响。【结果】磷肥的单独施用(35 kg/hm2)对云黄连生长的促进作用较小,而磷肥与复合肥混合施用[25 kg/hm2过磷酸钙和10 kg/hm2复合肥m(N)∶m(P)∶m(K)=18∶9∶5]可显著促进云黄连生长(P<0.05)。【结论】在保证云黄连优良品质的前提下,磷肥与复合肥混合施用能极显著地提高产量。本研究可为制定合理的云黄连规范化栽培管理措施提供科学的理论依据和实践基础。
[ Purpose ] The research about medicinal plant fertilization is very important for improving the yield and ensuring the quality of medicinal materials. [Method] The effect of application of phos- phate and synthetic fertilizers on growth traits, yield and quality of Coptis tecta Wall. was determined by the randomized blocks design of three replications. [ Results ] The phosphate fertilization （35 kg/ hm2） would not improve C. tecta growth. Application of phosphate and synthetic fertilizers together [25 kg/hm2 calcium superphosphate and 10 kg/hm2 compound fertilizer m （N） ： m （P） ： m （K） = 18：9：5 ] could significantly promote C. teeta growth （P 〈 0. 05 ）. [ Conclusion ] It was on good quality premise that mix phosphate and synthetic fertilizers could accelerate C. teeta growth and increase yield significantly. This research offered the theoretical and practical basis for standardized cultivating meas- ures of C. teeta.
