| Abstract: |
| Plot experiment was carried out to determine the suitable numeric range of low irrigation limit under subsurface drip irrigation in greenhouse,by comparing the plant height,stem diameter,fruit quality,yield and water use efficiency of tomato under different treatments.The results indicated that when the drip tubes were buried at 30 cm underground,the depth of designed moistening layer of soil was 15 cm～45 cm and the wetted ratio was 0.7,and the upper irrigation limit was field capacity on loam soil while the low irrigation limit was 30 kPa in soil water suction,the growth of tomato was good,and the objectives of high-yield,high quality and water-saving could be achieved. |
