| 摘 要： | 采用4因素5水平二次回归通用旋转组合试验设计,研究了氮、磷、钾和灌水量的耦合效应对日光温室生菜的影响。结果表明:4因素对生菜产量影响顺序是磷肥>氮肥>灌水量>钾肥;各因素之间存在交互作用,其中氮肥和磷肥、钾肥和灌水量的交互作用显著;经过计算机模拟,得到生菜高产的最适水肥管理措施。每公顷施氮量为467.9～586.5 kg、施磷量为510.5～622.3 kg、施钾量为156.0～221.5 kg和生菜生长期内累计灌水量为543.2～668.4 m~3。

| Abstract: | The comprehensive effects of K,P,N fertilizer and water on yield of Lactuca sativa L.was studied by means of quadratic general rotational(1/2 practice)combination design in the greenhouse.The water-fertilizer coupling regression models demonstrating the relationships between yield and four factors were established.The results showed thar,the effect of four factors on the yield of lettuce increased by degree in the series of P>N>K>water.The interaction among these four factors existed,coupling effect of N an... |
