【Background】 Tomato is a vegetable grown widely across Ningxia in greenhouses with the soil mulched. Drip irrigation is the main irrigation for greenhouse crops, but excessive irrigation is common resulting in not only water waste but also environmental contamination due to agrochemicals leaching. Increasing water use efficiency and reducing detrimental impact of the mulching film is hence critical to sustaining tomato production in Ningxia. 【Objective】 The purpose of this study was to find an optimal drip-irrigation scheduling and film mulching in attempts to provide guidance for improving water use efficiency while in the meantime increasing yield of the greenhouse tomato in Ningxia. 【Method】 A two-year experiment was conducted in a solar greenhouse with the soil either not mulched (M) or mulched (NM) with plastic film. Added to these were three irrigation levels by keeping the soil moisture at 100% (W1), 80% (W2) and 70% of the field capacity respectively, with the irrigation used by local farmers (123% of the field capacity) taken as the control (CK). 【Result】 It was the film much rather than the irrigation amount that affected the growth of plant height and stem diameter from seedling stage to flowering and fruit setting stage at significant level (P |
