以番茄为供试作物,在温室内采用二次D-饱和最优设计进行水肥试验,探讨了滴灌条件下水、肥交互对温室番茄产量的影响。试验结果表明:影响番茄产量的主要因素是灌水量与钾肥用量的交互作用,其次是氮肥用量;仅从产量角度评价,以中等氮肥用量、高钾肥用量和高灌水量为水肥调控的最佳组合。
Taking tomato as tested crop, water-fertilizer experiment was carried out in the greenhouse using the optimal design of secondary D-saturation, and the effects of water and fertilizer interaction on tomato yield in greenhouse were discussed. The results showed that the main factors influencing the yield of tomato were the interaction between irrigation amount and potash fertilizer, followed by the amount of nitrogen fertilizer. Only from the perspective of yield evaluation, the best combination of water and fertilizer was medium nitrogen fertilizer, high potassium fertilizer and high irrigation amount .
