Effects of soil water deficit on growth of potted peach trees under drip irrigation

This paper discusses the effects of soil water deficit at different growth stages of potted peach trees on fruit setting ratio, shoot and fruit growth. Data from experiments carried out in peach field were analyzed and soil water potential variation described The regularities of fruit setting ratio, shoot growth, fruit growth, fruit total soluble under different soil water deficit treatments were analyzed. The experimental results showed that, fruit setting ratio was related to soil water deficit, the severer soil water deficit the peach underwent, the less fruit setting ratio was; shoot growth under soil water deficit was slower than that under full irrigation; the effects of soil water deficit on fruit growth were complex; fruit total soluble wasn't affected during flowering but was affected during RDI stage.
