Abstract: Self-suction micro-irrigation is a new kind of micro-irrigation equipment. In order to prospect the better application of the new technology, in this paper, comparative analysis between self-suction micro-irrigation (SI) and furrow irrigation (FI) on growth and yield of Cucumis statirus L. was researched. Results showed that air temperature and soil temperature of the greenhouse under SI treatment both increased 9.6%, while air humidity decreased 4.4%; the SI treatment had a higher plant height and a larger stem diameter, besides that, it increased yield about 4.4%; meanwhile, daily water consumption of each growth stage was lowered and water consumption of entire period was about 54.9% of FI treatment; water use efficiency was promoted significantly under SI condition, it increased 130% and reached 60.8 g/kg. Therefore, since SI had a better working performance, saved water and increased yield, it is a suitable irrigation method for greenhouse.
