Abstract: In this paper, an experiment was conducted to study the impact of drought on the growth and the production of maize at the jointing-tasseling stage and the tasseling-mature stage. The soil moisture was controlled quantitatively in different growth periods by the movable water-proof canopy. The result shows that: compared with the suitable water treatment, the growth and development of maize were restrained by drought, and the yield decreased significantly. Compared with the drought at the jointing-tasseling stage, the drought at the tasseling-mature stage has less effect on the growth of nutritional organ, but has a greater influence on yield. The ear length, grain number per ear, ear dry mass and grain mass per ear decreased significantly, but the changes of ear diameter, length of bare tip and 100-kernel mass were insignificant compared with the suitable water treatment.
