Abstract
The effects of drip irrigation frequency and nitrogen fertilizer on water consumption of tomato in greenhouse were studied under sufficient irrigation,and the estimation accuracies of water consumption were discussed with different deep percolation interfaces and different types of soil water content sensors.The results indicated that there were no significant influences of irrigation frequency and nitrogen fertilizer on deep percolation and total water consumption.Deep percolation accounted for 13.8% of irrigation amount during tomato growth season.The total water consumption of tomato was 210.2mm,and the daily mean water consumption rate was 2.3mm/d.The deep percolation deviation rate between 40 cm and60cm interfaces accounted for 0.9%of irrigation amount,and their tomato total water consumption deviation rate was 2%.The deviation rate between tomato total water consumption estimated by Trime tubes and Hydra Probe sensors was 0.9%,while there was larger difference at different growing stages.The measurement of water consumption during the crop growing stages should be on the basis of soil water content measured by one type sensor continuously.The measurement of deep percolation might base on the depth where 80%root concentrated.
