Abstract:In this paper, an analysis is made by comparing the effects of three irrigation techniques, including drip irrigation, furrow irrigation under membrane and border irrigation, on the greenhouse environment, water consumption, yield and quality when they are used for the irrigation of cucumber grown in sunlight greenhouses and by comparing the output and input ratio when cucumber is grown in greenhouses where the same three irrigation techniques are adopted. The results indicate that, compared with border irrigation, drip irrigation lowers the relative humidity of the air in the greenhouse by 10 15%, increases ground temperature by 3 8 ℃ in winter, reduces water consumption of cucumber by 43.4%, whichmeans a saving of irrigation water by 59.9%, raises cucumber yield by 33%, achieves an output value increment of 67,500 yuan (RMB)/hm 2, increases the contents of crude protein and soluble sugar both by 4%, makes the marketable date of cucumber 10 days earlier and enhances the annual output and input ratio by 1.01. Also compared with border irrigation, furrow irrigation under membrane lowers the relative humidity of the air in the greenhouse by about 13%, reduces water consumption of cucumber by 13.6%, which means a saving of irrigation water by 20%, raises cucumber yield by 13%, achieves an output value increment of 31,500 yuan (RMB)/hm 2 and increases the annual output and input ratio by 0.82.
Keywords:cucumber grown in greenhouses  furrow irrigation under membrane  drip irrigation
