阶段性干旱对夏玉米生长发育及产量的影响
Effects of Phased Drought on the Growth Development and Grain Yield of Summer Maize
摘要
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 signiifcantly. 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 inlfuence on yield. The ear length, grain number per ear, ear dry mass and grain mass per ear decreased signiifcantly, but the changes of ear diameter, length of bare tip and 100-kernel mass were insigniifcant compared with the suitable water treatment.关键词
