摘要
以大丽花品种深玫红为试材,采用"3414"不完全正交回归设计,研究了不同氮、磷、钾施肥处理对盆栽大丽花生长发育、叶片及土壤有效养分含量的影响。结果表明,不同施肥处理能显著提高大丽花花量、花瓣数和功能叶片数,以N3P2K2处理的效果最显著。不同施肥处理对大丽花植株氮、磷、钾含量的影响不同。单因素分析表明,氮磷钾肥显著提高叶片氮、磷、钾含量。与对照相比,不同施肥处理的土壤有效养分含量均有所增加。
Taking Dahlia pinnata variety Shenmeihong as material, the effects of formulated fertilization with N, P and K on its growth and development and the nutrient contents in leaves and soil were studied through pot experiment with ＂3414＂ incomplete regression -orthogonal design. The results indicated that all the fertilization treatments improved the number of total flowers, petals and functional leaves significantly. The effect of N3P2K2 treatment was the best. Different fertilization treatments had different effects on the content of N, P and K in leaves. The single factor analysis indicated that fertilization improved the contents of N, P and K significantly in leaves. Compared with the control, the content of available nutrients in soil increased in different degree.
