| 摘 要： | 在云南省孟连县进行了山桂花人工林3年生幼林期施用N、P、K、NP、NPK、NK、KP肥及不施肥(CK)的试验,以观测其施肥效应。通过对各施肥处理的山桂花3年生幼林期林木的胸径、树高、材积、树冠生长的观测、分析,表明在山桂花3年生的幼林期间,对其幼林生长的促进作用。以施用N肥的效果最好;其次是施用NP肥;再次是施用NPK混合肥;第4是施用NK肥;另4种施肥处理(含CK),对山桂花幼树生长的促进作用不大。试验结果还表明,在山桂花3年生的幼林期内,2.5年生基本是其幼林径、高生长的高峰期;而年生长节律显现的是6~10月雨季山桂花林木的生长量比11月~次年5月旱季大得多。 |
| 关 键 词： | 山桂花人工林 3年生幼林期 施肥效应 |

| Abstract: | Experiments of fertilization effects on 3 years old Paramichelia baillonii plantation at Menglian county were conducted.The tested treatments were N,P,K,NP,NPK,NK and KP.According to the growth of DBH,tree height,volume and crown,it was concluded that at the sapling stage, the optimum fertilizer for Paramichelia baillonii plantation was N,next came NP,NPK and NK in order.The experimental results also indicated that 2.5 years old was the peak time in growing,and the growth in rainy season namely June to October was much higher than that from November to May. |
| Keywords: | Paramichelia baillonii plantation sapling stage of three years old fertilization effect |
