氮磷钾对阔叶十大功劳生长的影响

Effects of N ,P and K fertilizer on the growth of Mahonia healei

采用田间小区试验方法,研究了氮、磷、钾肥对阔叶十大功劳生长的影响。结果表明,氮、磷、钾肥不同配比对阔叶十大功劳的株高和茎粗有显著影响,在6种不同施肥处理中,以处理4(N50g/株,P2O5100g/株,K2O50g/株)最利于植株的生长。阔叶十大功劳小苗生长需要提供钾肥,3年生植株的生长需要补充氮肥。

The effects of N, P and K fertilizer on the growth of Mahonia healei was studied by the field plot experiment.The result showed that the effects of different ratios of N, P and K fertilizer on the growth of Mahonia healei were significant and the best ratio was treatment 4 （N 50 g/plant, P2O5 100 g/plant, K2O 50 g/plant） in the 6 treatments. K fertilizer could promote the growth of seedling. However, N fertilizer could promote the growth of plant of 3 year old.
