摘要
为探究N元素对杉木幼林生长的影响,2021年开展杉木幼林施肥试验,肥料为尿素,采用4个施肥处理,即30 g/株、60 g/株、90 g/株和不施肥对照(CK).结果表明:30 g/株施肥处理杉木树高和地径相对CK分别增长了 0.2％和38.3％;60 g/株施肥处理杉木树高和地径相对CK分别增长了 7.6％和54.2％;90 g/株施肥处理杉木树高和地径相对CK增长了 6.3％和62.2％.
Abstract
To investigate the effect of N element on the growth of young Cunninghamia lanceolata forests,in 2021,the fertilization experiments on young Chinese fir forests are conducted.The fertilizer is urea,and four fertiliza-tion treatments are used,namely 30g/plant,60g/plant,90g/plant,and no fertilization control(CK).The results indi-cate that:the relative CK of height and diameter of Cunninghamia lanceolata trees increased by 0.2％and 38.3％respectively under the fertilization treatment of 30g/plant;The relative CK of height and diameter of Cunning-hamia lanceolata trees increased by 7.6％and 54.2％respectively under the fertilization treatment of 60g/plant;The 90g/plant fertilization treatment increased the relative CK of Cunninghamia lanceolata trees by 6.3％and 62.2％,respectively.
