Experiment on drip irrigation schedule of cucumber in sunlight greenhouse

In view of water needs chara eteristics of the sunlight greenhouse cucumber,the paper carried out the experimental reasearch for the cucumber irrigation schedule by drip irrgation under membrane in sunlighe greenhouse,selected the irrigation volume and irrigation period as the test factors.In sunlight greenhouse the growing period of spring cucumber last for 92 days,the suitable irrigation times are 15~16,the average irrigaion interval is 5~6 days,the irrigation quota is 267~271 m3/hm2,so the total irrigation volwme in whole growing season is 4065~4275 m3/hm2,the estimated cucumber yield can reached 9.9×104 kg/hm2 above.
