Abstract. This study clarified the applicability of micro-sprinkler irrigation under plastic film (MSPF) in a greenhouse and finding the optimal micropores group spacing and capillary arrangement density. The effects of different micropores group spacing (L1: 30 cm micropores group

A completely randomized trial design was used, and drip irrigation under plastic film and micro-sprinkler irrigation were used as controls. The results showed that MSPF in a greenhouse can lead to saving water, increase yield, and improve crop quality. Compared to 50 cm micropores group spacing, 30 cm was better for tomato growth and also increased fruit quality, yield, and WUE. Considering our results comprehensively, the combination of one pipe for two rows under a micropores group spacing of 30 cm is recommended as technical parameters for greenhouse tomato cultivation under MSPF in arid and semi-arid sandy loam soils.
