| Abstract: |
| Under the condition of high-density planting and mulched drip irrigation, the rules of water consumption and yield of tomato are studied. The results show that the maximums water consumption period is from June 26 to August 7, CWC is 6.8 m
m in early July, CWC is 7.3 mm in mid July, CWC is 5.1 mm in late July, and the everyday capacity of water consumption (CWC) is 6.15 mm. When the average daily temperature is in 20℃～25℃, the maximum evapotranspiration is 205.19mm, the duration is 56 days, the CWC is 3.66 mm, and the total CWC is 205.19 mm. During this period of time, the frequency of drip irrigation should be 5～6 times, with a quantity of 40 mm in each time of irrigation, and the interval bwtween two time
s of irrigation should be 9～10 days. The field experiment shows that tomato yield increases gradually along with the increase of irrigation and, calculated by means of the regression equation, the maximum theoretical yield may reach 188.69 t/hm2. |
