| 1 | 施P肥和外生菌根菌接种对蓝桉林产量和养分积累的影响显示文摘主要研究施P肥和接种外生菌根菌对蓝桉生长、生物量和养分积累的影响。在云南楚雄的试验表明:接种外生菌根菌只能在幼林期促进树木生长,3a后这种促进作用不显著。施P肥能在幼林期促进蓝桉树高和胸径的生长,但4 5a后这种促进作用也变得不显著。由于施P肥提高了蓝桉的保存率,所以也显著地提高了蓝桉林的生物量。低P处理时,树木保存率低,较大的生长空间促进了树木的后期生长,可能会导致施P肥对后期单株蓝桉树高和胸径生长作用不显著。施P肥还增加了树木N、P和K的养分积累量,提高了上述养分的利用效率。施P肥同时还明显增加了林下植被和林下凋落物P的积累量,但不能明显增加N和K的养分积累量。树木叶片和土壤分析结果进一步说明施P肥对蓝桉幼林作用明显。试验表现出接种外生菌根菌只能在低P情况下促进树木生长,不能在高P情况下促进树木生长的基本趋势。 | 徐大平 Bernie Dell 弓明钦 Nick Malajczuk 王志和 | 2004 | 林业科学研究2004，17，1： | 10 |

| 3 | Nutrient Management for Eucalypt Plantations in South China显示文摘Eucalypts are very popular for revegetation in many parts of south China because of their capacity to tolerate degraded sites and unfertile soils,and their fast growth potential to coppice. This paper reviews a decade of field trials in china, undertaken as part of several bilateral researchprograms in plantation forestry, concerning the use of fertilizers, harvest residue management and inoculation with ectomycorrhizal fungi. One of the key questions addressed is whether the productivity of plantation ... | KU Daping Bernie DELL1. Research Institute of Tropical Forestry, CAF, Guangzhou 510520, China 2. Murdoch University.
