摘要
为了克服水稻田大量施用化学农药除草的弊端,对中稻和晚稻的稻鸭共生田中杂草种群的消长动态进行系统研究.结果表明,稻田养鸭对杂草的控制效果为98.5%～99.3%,比施用化学除草剂的效果高6.9%～16.1%.放鸭田不仅消除了杂草危害,而且省工、省药、增产、增收,是一项一举多得的生物除草技术.
In order to overcome the abuse of chemical pesticide weed in rice paddy,a systematic ecperiment is carried out on weeds populations dynamics in rice-duck intergrowth fields of middle rice and late rice.The results indicated that the control impact of feeding duck in rice paddy on weeds is 98.5%~99.3%, 6.9%~16.1% more than in pesticide area .In area of feeding ducks,the harm of weeds is removed,and it saves labor,saves pesticides and increases yield.It is a perfect technical measure of biology weed.
