摘要: 通过对短葶山麦冬生长周期内定期取样,测定植株不同时期和不同部位氮、磷、钾含量,结果表明:分蘖期、开花期、块根生长期和块根膨大期均为吸肥高峰期;每生产100kg干麦冬需吸收氮、磷、钾分别为5.17kg、0.69kg、4.83kg,对氮、磷、钾的吸收比例为1:0.13:0.74。Abstract: By regular monitoring the nutrients in various parts of Liriope.muscari(Decne.) Bailcy,the plant's N,P and K assimilation pattern throughout the growth periods was obtained.It showed that at the tilling,flowering,tuber-bearing and the tuber-expanding stages,a peak fertilizer assimilation occurred.For 100 kg dry liriope harvested,5.17 kg,0.69 kg and 4.83 kg of N,P and K,respectively,were needed,with an N P K assimilation ratio of 1:0.13:0.74.
