| Abstract: |
| The purpose of this experiment was proved the impact of aeration irrigation with different irrigation amount and different aeration irrigation frequency to the growth, yield and quality of greenhouse tomato, laid the foundation for the actual production application. Using the small plots for controlled trials in greenhouse, set three different crop-pan coefficients (Kcp=0.8, Kcp=1.0 and Kcp=1.2) and two aeration irrigation frequencies (1 time per 3 days, 1 time per 6 days) of total six treatments, all with non-aeration irrigation for contrast, comparing the impact of different treatments to the tomato growth, fruit yield and quality. The Results showed that: Under the same irrigation frequency and irrigation amount, the tomato growth, yield and quality can be improved by the aeration irrigation, the plant height increased 1.44%, stem diameter increased 3.03%, the yield increased 19.49%. The aerated irrigation was conducive to stem diameter, plant height growth of the greenhouse tomato, also was useful to improve the yield and quality of tomato. When adopted aerated irrigation treatments, under the condition of same irrigation amount, irrigation frequency 1 time per 6 days was better than 1 time per 3 days, the plant height was increased 8.08% and stem diameter was increased, 6.33%, the yield was increased 26.01%. We can obtain the conclusion that the impact of aerated irrigation on plant growth, fruit yield and quality was much better than the non-aerated treatment; irrigation frequency 1 time per 6 days and Kcp=1.0 was the most useful to the accumulation of the tomato growth, yield increase and quality improvement. |
