摘　　要：通过对施用硝酸钾肥和复合肥的比较试验 ,表明硝酸钾肥对促进黄山药 (Dioscoreapanthaica)地上、地下部分生长 ,提高次生根茎产量有显著效果。栽培 32个月的次生根茎平均生长量达 40 5 9± 2 5 4 0g/株 ,产量 5 8 5t/ha ,比施用复合肥的增产 37 5 %和 2 0 5 % ,比对照增产 2 9 9%和 17 9%。施用复合肥的次生根茎平均生长量 2 5 3 6± 148 6g/株 ,产量 46 3t/ha,比对照低 10 8%和 3 1%。Fertilizer KNO 3 has distinct effect on the output of aboveground and underground part of Dioscorea panthaica and increase the biomass of secondary rhizomes.After 32 months's growth period,the average individual biomass of secondary rhizome is 405.9±254.0 g and the hectare output is 58.5 t,increasing individual production 37.5% and 29.9% and hectare production 20.5% and 17.9% in compared with compound fertilizer and non fertilizer comparison respectively in 2 duplicates.The individual output of secondary rhizome with compound fertilizer is 253.6±148.6 g,with which the output in one hectare is 46.3 t,decrease 10.8% and 3.1% in individual and field output respectively.The content of diosgenin has no evident difference in these treatments.
