摘要
研究不同质量比的N、P、K、Ca、Mg五种主要养分元素的肥料组合对中苗期红掌品种"热情"的生长与N、P、K、Ca、Mg的吸收利用状况的影响。结果表明,5种元素质量比mN︰mP︰mK︰mMg︰mCa=1︰2︰2︰0.4︰0.6的肥料促进中苗期红掌地上部的生长效果最显著;其质量比为3︰1︰3︰0.6︰0.8的肥料对红掌地下部的生长最为有利,并使植株的总干物质积累量最高。中苗期红掌地上部对5种元素的吸收利用在其质量比为3︰1︰3︰0.6︰0.8的肥料中表现最优,同时,该配方的肥料也使地下部对5种元素的吸收量最高,但在不同肥料配方中地下部对各元素的利用效率却无明显规律性。
Through conducting the treatments of fertilizers constituted by different mass ratios of nitrogen,phosphorus,potassium,calcium and magnesium,the growth indices and nutrient absorption ＆ utilization of N,P,K,Ca,Mg were studied on the middle seedlings of Anthurium andraeanum Linden’Tropical’.The results showed that： for the growth of overground part of the middle seedlings,the fertilizer with a mass ratio was N ∶ P ∶ K ∶ Mg ∶ Ca = 3 ∶ 1 ∶ 3 ∶ 0.6 ∶ 0.8 was the best;for the growth of underground part of the middle seedlings,the fertilizer with a mass ratio was N ∶ P ∶ K ∶ Mg ∶ Ca = 1 ∶ 2 ∶ 2 ∶ 0.4 ∶ 0.6 was the best.The fertilizer with a mass ratio was N ∶ P ∶ K ∶ Mg ∶ Ca = 3 ∶ 1 ∶ 3 ∶ 0.6 ∶ 0.8 was the best one for nutrient absorption and utilization of N,P,K,Ca,Mg in overground part of the middle seedlings and also the best one for nutrient absorption of N,P,K,Ca,Mg in underground part of the middle seedlings,but the nutrient utilization of N,P,K,Ca,Mg in underground part seemed irregular.
