摘  要：
在云南省的孟连县开展营造山桂花人工林施用N、P、NP、NPK肥及其每种植穴用量为0 g、100 g、200g、300 g的不同施肥措施对3年生期间山桂花人工林林木生长影响的试验研究。试验结果表明,当3年生时山桂花人工林林木的材积不同施肥处理的比不施肥处理的高1.6~5.4倍。所施用的4种肥料相比较,施肥效果为:N>NP>NPK>P。其3年生山桂花人工林林木平均材积,施用N的比施用NP的高2.7%,施用NP的比施用NPK的高49.3%,施用NPK的比施用P的高191.8%。不同施肥量对山桂花人工林(3年生)林木生长的效应是P300 g>200 g>100 g>0 g;N和NP是200 g>300 g>100 g>0 g;NPK是300 g>100 g>200 g>0 g。受当地气候影响,山桂花人工林(3年生)的生长可分为两季,12月~次年5月处于旱季,因气温低,降水少其幼林生长慢,6~11月为雨季,气温高、降水足其幼林生长快,雨季生长量比旱季高50%以上。

摘  要：
Experiments were conducted in three years old Paramichelia baillonii plantation in Menglian county to study the effects of N,P,NP,NPK of different applying amounts on growth of plants.The experimental results showed that the volume under fertilization treatment was 1.6 to 5.4 times higher than plants without fertilization treatment.The effects of different fertilizers were ranked as N>NP>NPK>P.As far as the volume of three years old plants was concerned,those applied N was 2.7 % higher than NP,NP was 49.3 % higher than NPK,NPK was 191.8 % higher than P.The effect of different applying amount of P was 300 g >200 g > 100g > 0 g,ranks of N and NP were all 200 g >300 g > 100g > 0 g,and that of NPK was 300 g >100 g > 200g > 0 g.Influenced by the climate,the growth of saplings of Paramichelia baillonii could be divided into 2 seasons,December to next May was dry season,the growth of trees was slow owing to the low temperature,June to November was rainy season,the growth of trees was fast,the growth increment of rainy season was 50 % or more higher than dry season.
