Abstract:

Drought is one of the main meteorological factors affecting the growth and yield of maize. In order to find effective ways to reduce drought damage, keep maize yield and increase drought resistance of maize, this study introduced the chemical control technology of drought resistance in maize, concluded the effects of drought on seed germination and the physiological and biochemical indexes of maize seedling, reviewed the drought-resistance mechanism of plants, and summed up the application of chemical regulation in the drought resistance of maize. At last, the problems in the chemical regulation were pointed out, and some advices were proposed, including highlighting the research and application of mixed dosages.

Key words: maize, drought stress, physiological and biochemical index, drought-resistant mechanism, chemical regulation
