摘要
番茄畸形果的发生与氮、磷、钾营养水平有密切关系。苗期增施氮、磷、钾均会提高畸形果发生率、平均级数和综合畸形果指数。在氮、磷、钾三要素中，以氮对畸形果发生的影响最大，磷次之，钾在低浓度（１２０ｍｇ／Ｌ以下）时的影响较大，但超过一定浓度后作用减小。
During tomato seedling stage,the applications of nitrogen,Phosphorus and potassium nutrients could increase the incidence of malformed fruit,average grade and integrated index. Among the three major elements of N,P and K,nitrogen had the most important effect on occurrence of malformed fruit. Phosphorus was the next. Potassium could give strong effect in the concentration below 120mg /L. Little effect was found if potassium was over this concentration.
