摘要
试验结果表明,常规施肥基础上麦冬施钾效果显著。麦冬对氮磷钾的吸收比率为N∶P∶K∶=1∶0.18∶0.7。钾肥能明显提高植株干物重,并有利于碳水化合物向根部运输积累,促进植株对氮磷钾的吸收。
The article reports the effects of N and K fertilizer supplement on the output and nutrient absorption of Ophiopogon japonicus. The result showed that the effect of k was quite notable. The ratio of Ophiopgon japonicus absorption on N, P and K was N:P:K= 1: 0.18:0.7. K fertilizer benefit the transportation and accumulation of carbonhydrates to root and accelerated the absoption of N, P and K. plant dry wight was increased for the application of K fertilizer.
