摘要
[目的]通过在保护地番茄上进行水肥一体化应用,确定最佳灌溉量和最佳施肥量。[方法]在管理水平一致的条件下,设置2个处理,进行水肥一体化技术与常规灌溉和施肥条件的处理。[结果]不同灌溉方式对比试验表明,应用水肥一体化技术能够增产8.8%、节水22.7%、节肥20.69%。初步确定了保护地番茄最佳灌溉量为2 184 m3/hm2、氮、磷、钾肥料的最佳施用量为420、263、240 kg/hm2。[结论]温室蔬菜水肥一体化技术可进行大力推广。
Objective] Through the application of integrative water and fertilizer in greenhouse tomato, the optimum irrigation and fertilizer amount were determined. [Method] 2 treatments were designed？under the same management conditions. Integrative water and fertilizer technique and conventional irrigation were compared. [Result] The comparison of different irrigation methods test showed that there were an increasing yield rate of 8.8%, saving water rate of 33.5%and saving fertilizer rate of 33.5%. [Conclusion] Tomatoes best irrigation amount was 3 750 m3/hm2 and nitrogen, phosphorus potassium fertilizer content were 420, 165, 75 kg/hm2 respectively.
