摘要
以铜仁市马尾松幼林为研究对象,研究不同施肥处理对其生长量、新鲜针叶营养物质含量的影响。结果显示,包膜型缓释氮肥(V_(N)∶V_(P)∶V_(K)=18∶5∶12)施用量为2000 g/株时,马尾松幼林的平均胸径、总胸高断面积、蓄积量、新鲜针叶营养物质含量最高,植株生长情况最佳。
Taking young plantations of Pinus massoniana in Tongren City as the research object,the effects of different fertilization treatments on its growth and the content of nutrients in fresh needles were studied.The results showed that the average diameter at breast height,total thorax height area,storage volume and fresh needle nutrient content of young plantations of Pinus massoniana were the highest when the application rate of enveloped slow-release nitrogen fertilizer was 2000 g/plant,and the plant growth was the best.
