摘要
2011-2013年在江苏省江阴市开展了稻鸭共作有机稻生产与鸭子安全放养技术的研究。结果表明,提高栽插密度是稻鸭共作有机稻取得高产的关键;40.0℃是稻田鸭子生存的极限高温,在36.0℃~38.5℃的连续高温条件下,通过灌20 cm左右的深水层,并采用边灌边排的方法可有效防止鸭子中暑死亡;将两块稻田隔成一个围养单元,通过两块稻田轮流搁田的方法可有效解决水稻中后期的水分管理。
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 improve 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 20cm 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.
