| 摘 要： | 为了探讨氮肥对松树苗木生长的影响,以油松和樟子松为试验材料,对这2种松树的高度和生物量的变化及转移情况进行研究。结果表明:施用氮肥对油松和樟子松高度的生长有显著影响,依次为高氮中氮低氮;低氮肥处理的地上生物量最高,中肥和高肥处理的生物量向根系转移量降低,3种施肥处理均以高氮量处理生物量最低。

Effect of Nitrogen Fertilizer on Growth of Two Kinds of Pine Seedlings |
| |
| Abstract: | In order to investigate the effect of nitrogen fertilizer on the growth of pine seedlings,taking Pinus tabuli-formis and Pinus sylvestris var.mongolica as material,change and transfer of height and biomass for these two kinds of pine were studied.Result shows that nitrogen fertilization have significant effects on the growth of height for Pinus tabuliformis and Pinus sylvestris var.mongolica.Followed by high nitrogen>middle nitrogen> low ni-trogen;biomass of pine treated with low-nitrogen fertilizer is highest;the amount transferred to the root of biomass of pine treated with middle and high fertilization treatment reduced;biomass treated with high nitrogen is lowest a-mong three kinds of fertilization. |
