摘　　要：目的:研究有机肥和磷肥不同梯度施肥水平对直缘乌头产量的影响。方法:采用单因素随机设计研究有机肥和磷肥对直缘乌头块根商品产量、苗块根产量及总产量的影响。结果:直缘乌头商品块根产量与有机肥施用量呈正相关关系,有机肥施用量高于2 00kg/667m2对苗块根的产生没有显著差异,在中等以下的土壤肥力条件下,有机肥最佳施用量为3 00kg/667m2。直缘乌头栽培对磷肥较为敏感,过量磷肥易对商品块根的生长可产生肥害,磷肥最佳施用量为30kg/667m2。结论:施用适量的有机肥和磷肥可显著提高直缘乌头产量。Objective]The study is on the the effect of different fertilizer levels on yield of Aconitum transsectum Diels.[Method]To adopt different grading levels amount of organic fertilizer and phosphate fertilizer to study the output of transsectum big roots used as commodity,small roots used as seedling and total yield.[Results]The per unit area yield of of Transsectum big roots was positively correlated with the amount of organic fertilizer;Organic fertilizer above 2 000kg/667m2 has no remarkable difference on small roots For soil fertility below medium,the suitable amount of organic fertilizer is 3 000kg/667m2;Transsectum are quite sensitive to phosphate fertilizer,overdose would be harmful to the gowth of big roots.[Conclution]Appropriate organic fertilizer and phosphate fertilizer can improve remarkably the output of Aconitum transsectum Diels.
