The invention provides a method for efficient zizania aquatica chilo suppressalis and rice chilo suppressalis breeding. The method includes that a first device and a second device are provided, wherein the second device comprises a colorless and transparent 500ml glass bottle; four layers of gauzes are paved at the bottom of the glass bottle, and a filter sheet is cushioned on the gauzes; three sections of fresh zizania aquatica are placed above the filter sheet in a triangle mode, and one layer of preservative film and one towel block are sequentially placed on the zizania aquatica; then, the opening of the glass bottle is covered with black cloth which is tightened through a rubber ring; or the second device comprises a colorless and transparent 500ml glass bottle; a wetted filter sheet is paved at the bottom of the glass bottle; rice seeds already sprouted are sown on the filter sheet, and when rice seedlings grow by 4-5cm, one layer of preservative film and one towel block are sequentially placed above the rice seedlings; after that, the opening of the glass bottle is covered with the black cloth which is tightened through the rubber ring. The chilo suppressalis can be gathered at one place for pupation, so that efficiency of pupa collection is improved, and death rate of the pupa is greatly reduced.

The invention discloses a sewage water treatment method of a large-scale pig farm. The method comprises the steps of 1), dry collection of excrement; 2), putting together of excrement and sewage; 3),solid and liquid separation of the excrement and the sewage; 4),anaerobic fermentation and degradation treatment of the sewage; 5), returning to field of the processed water which is used for plantingrice or zizania aquatica; 6), harvesting of the rice or the zizania aquatica which is used for feeding pigs in the pig farm. By means of the method, the sewageof the pig farm can be effectively treated, the processing effect is good, the integration of culturing and planting is achieved, and circulation agriculture is achieved, which is environmentally-friendly and free from pollution; culturingcost of the pig farm can be reduced to increase operating benefits of the pig farm. According to the method, sows are fed by using harvested zizania aquatica which is planted by using processed waterof the pig farm as the base fertilizer and the applied fertilizer, constipation of pregnant sows can be relieved, lactation of lactating sows is improved, weaning litter weight of piglets is increased, and feed cost is saved.
