| With pot experiment, the effects of different soil water levels (60%～65% (W1) , 75%～80% (W2) , 90%～95% (W3) of field moisture capacity) and two Zn solutions (0% (Z0) 、0.2% (Z1) ) on the growth, yield, quality, water consumption and WUE of tomato fruit were studied.The results indicated that the plant height and biomass increased obviously with the increase of soil water, that is the biomass of W3 treatment was 20.8% and 35.9% higher than W2 and W1, but the changes of fruit yield performed for the first rise after the lower trend, that was W2>W3>W1.Fruit yield decreased significantly with excessive soil water or soil drought.There was no significant difference in biomass with spraying Zn on leaves.However, the fruit yield of W1, W2 and W3 increased by 9.4%, 9.2% and 3.1%, and the taste and quality of fruit improved.The improvement of soil moisture to the plants increased water consumption, but WUE declined.There was no significant difference at WUE of biomass level with soil water and spraying Zn on leaves, but significant difference at WUE of fruit yield and nutritional components level.W2Z1 was the best treatment with high WUE of fruit, with WUEyield=61.62 kg/m3, WUEVc=9.56 mg/m3, and WUEsugar=4.7 g/m3. |
