- Abstract:
- In order to lay out the excellent capability of the sectional subirrigation and its higher water productivity, the subirrigation quality was checked out. The water productivity by 4 irrigation ways were compared. The study results showed that the soil moisture uniformity exceeded 90% and get higher 15% than ordinary subirrigation. The principles of saving water is translating whole profile wetness into root irrigation. The water seep can be effectively held back by paving impervious barrier. The irrigation water can be saved by shallow plan humid layer and little quantity watering once in a while. Comparing the water productivity with 4 kind of irrigation ways, the best way is sectional subirrigation (70.37 kg/m3), the second is ordinary subirrigation (54.55 kg/m3), the third is dripping irrigation under film (53.96 kg/m3) and the worst one is furrow irrigation (42.00 kg/m3).
