Abstract

To study the technological theory and economic benefit of which rice planted on ridge and fish reared in ditch, we conducted the experiment. The results showed that: a) the technology can optimize the ecological environment of paddy; increase soil water storage and decrease weed harm. b) It can improve economic benefit. The margin of the model was 22.85% compared to 16.22% for traditional rice and advanced seven points. c) It can bring good social effect, such as increasing total fish protein in society, promoting labor transformation and improving labor value. d) It have good ecological benefit, such as coordinating ecological niche of different species and ridge planting can provide good environment for rice. The model can create a best ecological environment for rice and fish, so as to achieve the rice and fish double harvest.
