摘　　要：以草石蚕为试验材料,研究氮磷钾肥配施对草石蚕产量及其构成因素的影响。结果表明:草石蚕单株结块茎数、单块茎重、大块茎率及产量均以处理N_(2)P_(3)K_(1)(纯N 146.67 kg/hm^(2)、P_(2)O_(5)140.00 kg/hm^(2)、K_(2)O 73.33 kg/hm^(2))最高,均与空白对照差异显著。Taking Stachys sieboldii Miq.as test material,the paper studied the effects of combined application of nitrogen,phosphorus and potassium on its yield and yield components.The results showed that N_(2)P_(3)K_(1)(pure N 146.67 kg/hm^(2),P_(2)O_(5)140.00 kg/hm^(2),K_(2)O 73.33 kg/hm^(2))were the highest in the number of tuber per plant,single tuber weight,large tuber rate and yield,which were significantly different from the blank control.
