摘要
[目的]探索宁夏地区设施蔬菜生产水肥高效利用模式。[方法]应用单棚简易精量水肥一体化灌溉设备,研究不同灌溉频度对春茬日光温室番茄生长的影响。[结果]全生育期平均灌溉量1 475.00 m^3/hm^2,追肥量2 156.48 kg/hm^2条件下,每7 d滴灌1次,单果质量180.23 g,产量160 814.81 kg/hm^2。[结论]每7 d滴灌1次省时、省工,可作为设施番茄水肥一体化最佳灌溉制度应用推广。
[Objective] In order to explore the efficient mode of water and fertilizer in protected vegetable production of Ningxia. [Method] Simple and accurate irrigation equipment was used in single greenhouse, study on the effects of different irrigation rates on growth and development of protected tomato were done in January. [Result] The average irrigation amount was 1 475 m^3/hm^2 and the fertilizer rate was 2 156.48 kg/hm^2 during whole growth period, irrigated by every 7 days, the fruit weight was 180.23 g, the yield was 160 814.81 kg/hm^2. [Conclusion] This irrigation mode saved time and labor, it could be used as a good irrigation schedule of integrative water and fertilizer in greenhouse tomato production.
