| In order to verify the effects of moistube-irrigation on the growth of tomato and water condition of soil, three different buried depths and two different pressure heads were designed. In addition, the resulting the effects were further analyzed on the growth and yield of tomato and water use efficiency. The results showed that after 94 days of planting, the buried depth at 15 cm had the highest plants which were increased by 9.17% and 7.55% from the buried depths at 10 cm and 20 cm, respectively. At this time, tomatoes had the minimal stomata conductance and highest photosynthetic rate and WUE within all of the four treatments employed in this investigation, resulting in yield increases of 3.24% and 7.45% more at buried depth at 15cm than those at buried depths at 10 cm and 20 cm, respectively. The temporal variations of soil water content along vertical distribution were different under different buried depths, with the buried depth at 15 cm the highest. The buried depth of moistube was the main factor influencing the temporal variations of soil water content. However, the effects of temporal variations of soil water content under different pressures were secondary. |
