摘要： Maintaining a stable soil water supply is the key for solar greenhouse vegetable production across the North China Plain. A three-season field experiment was conducted over 2 years to evaluate two methods of applying Yamazaki tomato nutrient solution (negative pressure and drip fertigation; NF and DF, respectively) for production of greenhouse tomato and water use efficiency (WUE). Soil moisture in the surface (0-20 cm) and entire soil profile (0-100 cm), as well as soil water storage (SWS) and crop evapo-transpiration (ET) levels were measured during the growing season. Then, plant growth, fruit yield, and WUE were compared. The variations in soil moisture (0-20 cm) were small for the NF treatment, with ranges of 20.0-25.0% and 22.2-24.3% in the early spring and autumn Winter seasons, respectively, which were less than the ranges of 19.7-28.5% and 21.4-26.7% for DF. The average SWS did not significantly differ between DF and NF treatments, while SWS in NF (318.6-339.3 mm) during the growing season showed small fluctuations compared with DF (315.7-342.9 mm). The ET over the whole growing season varied in the range of 224.0-319.9 mm, which was higher during fruit-set and flowering than other growth periods. With its higher irrigation amount, DF had a higher ET level than NF, but there was no significant difference in early spring. The consecutive and stable water supply of NF improved tomato plant height and stem diameter (P< 0.05) and improved fruit yield and WUE by 1.6-8.2% and 9.9-30.5% (P<0.05), respectively, compared with DF. These results demonstrate that the NF system can save more water (11.3% and 32.0% in the ES and AW seasons, respectively) than DF. As a new mode of integrated water and fertilizer management, NF is appropriate for vegetable production in solar greenhouses. (C) 2016 Published by Elsevier B.V.
