Abstract：This paper investigated the impact of drip irrigation (DT),sprinkler irrigation (CT) and surface irrigation (ST) on growth of transplanted fast-growing cotton seedling using pot experiments.During the experiment,water consumption,root growth,accumulation of dry matter,dry matter,as well as water use efficiency (WUEm)was measured.The results showed that the growth of the above-ground dry matter under the three irrigation methods was approximately the same,but DT and ST reduced the water consumption by 30.8％ and 14.4％ respectively compared with CT.The root length per plant in all three irrigation methods was almost the same,while DT considerably increased the root-shoot ratio,single root length and WUEm.DT promoted root growth without scarifying above-ground biomass accumulation,thereby benefiting the reproductive growth of the plant at late stages.
