Abstract: Puyang City in summer maize growth period, drought, floods and other weather disasters occur frequently. In order to study during the growth of summer maize in Puyang drought, floods and other weather disasters on the growth and yield of the, study of drought, flood prevention measures; This paper made a systematic analysis on Puyang in 1953-2012, nearly 60 years of drought, floods and other weather disasters, and discussed the influence of different degree of the disaster on the growth and yield of summer maize. The results showed that, the drought and flood disasters on summer maize growth and yield harm was bigger, tend to affect the summer maize yield abundant, owe. Puyang 60 years 1953-2012 corn yield typical climate owe a total of 19 years, which affected by drought and years of production had 12 years, affected by the flooding year for seven years. Puyang summer corn "drought and waterlogging disasters mitigation defense technology was mainly to disasters preventing and resisting, subtract, fill". Raising our every generationquality varieties, still should be adopted timely early sowing, ridge tillage cultivation and intertillage farming practices and management measures, such as digging. In order to extend the corn growth period, to accumulate more nutrients, increase sunlight hours, thus reducing the disaster effect on maize growth and yield. And targeted to strengthen the monitoring, early warning of meteorological disasters and drought and defense, In order to ensure the summer corn production safety, and provides a powerful reference for disaster prevention and mitigation.
