| Abstract: | A trial in 2004 indicated that raising fish in non - tilling rice filed as an ecological planting and raising model, could effectively improve the ecological environment of paddy fields, increase the number of natural enemies and decrease the number of rice planthopper, and that the number of rice plant- hoppers decreased by 30% compared to that in non- fish- raising paddy fields. At the same time, the application of pesticide requirement was decreased as well. |
