摘要
试验于温室进行 ,利用正交试验及灰色关联度分析 (综合评价指数 ) ,研究了四种代用基质与施肥方法对蝴蝶兰生长发育的影响。结果表明 ,蕾期施肥和基质类型是影响蝴蝶兰开花数量的主要因子。灰色关联度最高 (Ri=0 .6 9337)的处理组合是水藓基质施肥 2 0 0(N ,mg/L) ,N P (P2 O5) K (K2 O ) =15 15 15,现蕾后以磷钾肥加微量元素处理 ;其次是锯末+沙 ,施肥 2 0 0 (N ,mg/L) ,N P K =2 0 10 10 ,现蕾前用磷钾肥加微肥处理 ;三是花生壳 +沙 ,施肥量 10 0 (mg/L) ,N P K =15 15 15。沙 +KD 1型高吸水树脂基质的Ri
Effects of different media(four type)and methods of NPK fertilization on growth and flowering of Phalaenopsis hybridium were studied in greenhouse with method of orthogonal design and gray relational grade analysis(complex index of evaluation).The results showed that media and fertilizing method were the two dominating factors which influence number of flowers.The maximum gray relational grade(Ri)was obtained by the treating combination of N 200mg/L with N P K=15 15 15,PK plus micro nutrients applied after budding and sphagnum(SP)medium.The second one was obtained by the treating combination of N 200mg/L with N P K=20 10 10,PK plus micro nutrients applied after budding and the mixture medium with saw dust and sand(1∶1).The third one was obtained by the treating combination of N 100mg/L in ratio of N P K=15 15 15 and the mixture medium with peanut hull and sand.The lowest R i was obtained by the miture medium with sand and KD 1 Hydrophilic gel.
