Effects of Soil Water Deficit on Growth of Potted Peach TreesUnder Drip Irrigation

摘要

This paper discusses the effects of soil water deficit at different growth stages of potted peach treeson fruit setting ratio, shoot and fruit growth. Data from experiments carried out in peach field were analyzedand 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 showedthat, fruit setting ratio was related to soil water deficit, the severer soil water deficit the pea ch underwent, theless fruit setting ratio was; shoot growth under soil water deficit was slower than that under full irrigation; theeffects of soil water deficit on fruit growth were complex; fruit total soluble wasn't affected during floweringbut was affected during RDI stage.
