摘要
针对目前水资源紧缺与蔬菜生产用水的矛盾,采用滴灌、渗灌等新的节水灌溉技术与传统漫灌方式进行比 较,研究了3种不同灌溉方式对番茄植株生长、产量和品质的影响和节水效果。试验表明,滴灌和渗灌灌溉方式的植 株生长和产量都较漫灌方式有较大的提高,可溶性固形物含量增加;采用滴灌和渗灌栽培的灌水量显著减少,极大地 提高了水分生产率。
According to the contradiction between water resources shortage and vegetable production, the new irrigation methods of subsurface irrigation and drip irrigation were compared with flood irrigation. The effect of different irrigation methods on the plant growth, yield of tomato and irrigation rate were studied. The plant growth and yield under subsurface irrigation and drip irrigation were higher than those under flood irrigation, the soluble solid contents under subsurface irrigation and drip irrigation were also increased. The subsurface irrigation and drip irrigation decreased significantly the irrigation rate and increased significantly water use efficiency.
