摘　　要：为探究氮肥施用对松树苗木生长的影响,以山东临沂地区的广林9号桉树为研究对象,考察不同氮肥施用量对松树苗木树高、胸径、地径及生物量生长情况的影响。结果显示,不同氮肥施用量均对松树苗木树高、胸径、地径及生物量生长具有促进作用,综合经济效益和松树苗木的生长状况,推荐氮肥施用量为30 g/株,有利于改善松树苗木生长状况,提高松树的经济效益。In order to investigate the effects of nitrogen fertilizer application on the growth of Pinus seedlings,Eucalyptus Guanglin No.9 in Linyi was selected as the research object to investigate the effects of different nitrogen fertilizer application rates on tree height,DBH,ground diameter and biomass growth of Pinus seedlings.The results showed that different nitrogen fertilizer application rates had a positive effect on the growth of tree height,DBH,ground diameter and biomass of Pinus seedlings.The comprehensive economic benefit and growth status of Pinus seedlings were analyzed.The selection of 30 g/plant nitrogen fertilizer application rate was conducive to improving the growth status and economic benefit of Pinus seedlings.
