| Research on drip irrigation about different irrigation quota for growth and yield of tomato, analyzes the full irrigation and different water stress on the dynamic changes of soil moisture, and discussed tomatoes nutrition growth、yield、WUE and economic benefits at different water treatments and irrigation methods. The results showed that: (1) The water amplitude are differents in different layers of different water treatments on mulch drip irrigation, severe stress amplitude maximum, full irrigation less than it 4%～5% for each time; (2) the trends is consistency about soil moisture and the height of tomato, the impact was not obvious on stem diameter, the plant height、stem diameter large than severe stress were 44.7% and 18.5%, tomato exhibited different growth compensation after each stress irrigation treatment; (3) The WUE、yield and economic benefits respectively were 26.64 kg·m-3、75 349 kg·hm-2、49 747 yuan·hm-2 after full water drip irrigation treatment, higher than furrow irrigation were 37.1%、3.8% and 3.7%. |
