| Abstract: |
| The main purpose of this article is to show the variation of soil moisture of spring wheat field under the condition of different irrigation treatments. The experimental results show that: the probability of the variation of soil moisture on vertical direction under different irrigation treatments is the same, and the coefficients of variation of the probability of soil moisture become smaller and smaller as the depth increases; At the period of jointing which is in the highest need of water, all of the intensity of water consumption under different irrigation treatments achieve to the maxi-mum during the whole period of spring wheat growth; From water-saving irrigation treatment T3 can obtain the best effect under different imigation levels, because of the better using water and imigation water and the best imigation level. So that it can achieve the effect of water-saving irrigation. |
