摘　　要：以不施肥、浇灌营养液和施用等量NPK养分化肥作对照,对不同用量的控释复合肥在甜椒育苗中的应用效果进行了研究。结果表明,控释复合肥比普通化肥更有利于甜椒出苗,与化肥等养分含量的控释复合肥处理的秧苗肥料利用率显著提高,在控释复合肥用量减少20%的条件下,甜椒幼苗的生物量、壮苗指数、叶绿素含量、花芽分化水平均能达到浇灌营养液和施用普通化肥的效果。以上表明,控释复合肥用于甜椒育苗效果明显,具有一定应用前景。A trial was conducted to evaluate the effects of controlled-release and common compound fertilizers with various rates in nursing media on growth and fertilizer use efficiency of pepper seedlings ,using no fertilizers, nutrient solution and equal rate of NPK common compound fertilizers as controls. The results indicated that controlled-release and common compound fertilizers is advantageous to emergence of pepper seedlings, the treatment of equal rate of NPK controlled-release and common compound fertilizers had the best effects on fertilizer use efficiency, when the rate of NPK controlled-release and common compound fertilizers reduced by 20%, biomass, the sound seedling, the chlorophyll content, floral bud differentiation levels of pepper seedlings had the same good effects as nutrient solution and common compound fertilizers. The results of this study suggested that the controlled-release and common compound fertilizers may have potential as a commercial controlled-release fertilizer.
