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 值最低
The experiment was carried out in the greenhouse. The effects of four kinds of alternative substrates and fertilization methods on the growth and development of Phalaenopsis were studied by orthogonal test and gray relational analysis (comprehensive evaluation index). The results showed that budding stage and substrate types were the main factors influencing the flowering of Phalaenopsis. The treatment combination with the highest gray correlation degree (Ri = 0. 6 9337) was fertilized by 200% (N, mg / L) and NP (P2 O5) K (K2O) = 15 15 15, Followed by sawdust + sand, fertilization 200 (N, mg / L), NPK = 210 10 10, treated with phosphorous and potassium fertilizer plus micronutrient before budding; third, peanut shell + sand, Fertilizer amount 10 0 (mg / L), NPK = 15 15 15. Sand + KD 1 type superabsorbent matrix has the lowest Ri value
