Abstract: Irrigation scheduling of greenhouse vegetable has a strong regional suitability,in order to obtain appropriate drip irrigation scheduling of cucumber under solar greenhouse in coastal area of Tianjin,an experiment of six combinations of irrigation rate one time and irrigation interval was carried out in spring season,particularly including T1(6 mm+3 d),T2(12 mm+3 d),T3(18 mm+3 d),T4(12 mm+6 d),T5(18 mm+6 d)and T6(24 mm+6 d). It was showed that the yields under six treatments were respectively 75 056,79 352,80 042,73 023,76 398,78 891 kg/ha,correspondingly,the values of irrigation water efficiencies were 397,257,187,386,307,255 kg/mm. Generally,greater irrigation water rate or lower irrigation interval was beneficial to obtain higher production of cucumber,however,there were down trends of quality and irrigation water efficiency of cucumber with adding irrigation water rate. Therefore,it is recommended that the T2 treatment,12 mm of irrigation rate one time and 3d of irrigation interval,is suited for the cultivation of cucumber under solar greenhouse in spring,comprehensively considering factors of yield,quality and water-saving of cucumber.
