【摘要】 用3种农家肥(圈肥、油枯、柴灰),3种一元化肥(尿素、过磷酸钙、氯化钾)和复合肥,经2年对艾纳香(Blumea bal-samifera)的试验观察认为:施肥比CK生物产量增加,有效成分含量不减。施用多元肥比一元肥产量和有效成分含量都有提高,且较稳定。其中N素主要增加生物产量,药用有效成分含量与K肥用量呈正相关。更多还原

【Abstract】 Application trials of 3 farm manures(manure, rapeseed cake,plat ash),3 single element chemical fertilizers(urea,calcium phosphate,potassinm chloride) and a composite fertilizer on Ai-na-xiang(Blumea balsamifera) were conducted at Libo county for two years,The results showed that the treatment of applying fertilizers got higher yield with stable efficacious ingredients contents than that of non-fertilization;applying multielements fertilizers increased both of yield and efficacious ingredients and more stable than that of applying single element fertilizer;the increase of biological yield mainly depended on nitrogen and the medical efficacious ingredients showed positive correlation with the applying amount of potassium fertilizer.更多还原
