This pattern, of which both livestock's and crops were cultivated and the latent energy was tapped through the food chain which is consisted of vegetable hog marshgas fish , can improve energy conversion ability of the system. Furthermore, the reuse of straws as green manure crops can improve the soil fertility and keep the ecological balance of the system. All these were quantitatively managed for increasing agricultural sustainable development.
