稻田养鸭防控福寿螺试验

稻田养鸭防控福寿螺试验(8000字)
摘　要: 为了探索出一套可操作性强、易推广、安全、高效的稻田福寿螺生态防控技术，于2010年4月～7月在湖南省浏阳市通过采用不同鸭品种和不同养鸭密度对稻田福寿螺的防控效果及水稻产量的影响进行了对比试验。试验结果表明：稻鸭共育的生产模式对防控稻田福寿螺的效果十分显著。当稻田养鸭时间达到40d时，对福寿螺的平均防治效果达到93.94%；当稻田养鸭密度在6～14只/667m2时，鸭子对稻田福寿螺的平均防效与养鸭密度成正相关；鸭子对福寿螺的平均防效与时间成正相关；采用金定鸭防控稻田福寿螺效果和提高水稻产量幅度都极显著优于本地麻鸭。当稻田养鸭密度在6～14只/667m2时，稻田养鸭密度与水稻产量成正相关；当稻田养鸭密度在14～22只/667m2时，平均水稻产量与稻田养鸭密度成负相关；当稻田养鸭密度为14只/667m2时，对稻田福寿螺的防控效果最佳，平均水稻产量也达到最大值。

Research on Rice-Duck Integrated Farming in Controlling the Golden Apple Snail
Abstract: For the sake of exploring a suit of technique of maneuverability strong, popularizing easy, safety, efficiency high, on controlling the golden apple snail in paddyfield, the authors experimented on impact of controlling the golden apple snail and of heightening rice-output by ducks of different kinds, density of breeding ducks, using pesticide general in the paddyfield in 2010. Results show that: The effect of two duck’s varieties controlling the golden apple snail is 80% over when the time is 30d~60d. The effect on controlling the golden apple snail correlate positive with the density of breeding ducks when it is 6～14/667m2. The effect of controlling the golden apple snail correlate positive with the time of breeding ducks. The heightening rice-output correlate positive with the density of breeding ducks in 6～14/667m2 range of density. The range of heightening rice-output is breeding ducks is 14/667m2, it has the best effect on controlling the golden apple snail in paddyfields,
