稻鸭共育应用技术研究

通过田间实验，进行了稻鸭共育技术应用研究。结果显示：每667m2稻田放养25只鸭子，稻鸭共生期60～70d，以鸭粪肥田，基本能满足水稻生长所需的追肥；除草、除虫效果显著，可以取代化学除草和减少病虫害药剂防治，促进稻田生态良性循环。水稻产量增加，效益可观，因此本地区适合稻鸭共育技术大面积的推广。

Study on the Rice-duck Farming Applied Technology

The effect of rice-duck farming technology has been conducted through field experiment,the re-sults show： if 25 ducks would be stocking in every 667m2 rice farms,the symbiosis time of rice and duck would be approximately 60~70 days and the excrement of ducks would satisfy the top application of rice. Weeding,pest control effectiveness was so apparent that chemical weeding and chemical control of insect pests could be reduced or even repalced.Rice-duck farming technology could promote the benign cycle in paddy field ecosystem and increase production.As a result this area is suitable for Rice-duck farming tech-nology and should be applied extensively.
