WANG Jiangang;XU Demei;ZHOU Yan;DONG Guichun;Jiangyin Agricultural Technology Promotion Center;College of Agriculture, Yangzhou University ,Key Laboratory of Crop Genetics and Physiology of Jiangsu Province , A Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions, Key Laboratory of Crop Physiology, Ecology and Cultivation in Middle and Low Reaches of Yangtze River of Ministry of Agriculture;  
The current study was conducted in Jiangyin which was mainly focused on organic rice production and security technology of duck raised, namely rice-duck farming from 2011 to 2013. The results showed that the key to achieve high grain yield was to im-prove seedling density under the culture of rice-duck farming; forty degrees is the highest temperature that duck survived in paddy field. During continuous high temperature(36℃~38.5℃), it could effectively prevent the ducks died of sunstroke by irrigating 20 cm deep layer water and adopting irrigation and drainage method; combining two piece of paddy field into a compound unit, with the method of field draining in turn, the water during mid and late rice growth period could be effectively managed.
