One, fish - mulberry - chicken pond fish, mulberry species around the pond, mulberry within the park. Fish pond sludge and chicken manure are used as mulberry fertilizer, silkworm cocoon and mulberry leaf feed chicken, silkworm feces and chicken manure feed fish. Make mulberry, fish, and chicken form a good ecological cycle. The test showed that every 500 kg of mulberry leaves feeding silkworm, silkworm feces feeding fish, can increase fish yield 25 kg, mulberry gardens raise 20 chickens, annual production of chicken manure 1200 kg, equivalent to mulberry garden application of nitrogen fertilizer 18 kg, phosphate fertilizer 17.5 kg. Second, chicken - pig - cattle feed chickens, chicken manure after treatment of pigs, pig manure after treatment of cattle, cattle manure as farmland fertilizer, which greatly reduces the contradiction between livestock and man for food, effectively reducing the cost of feed. Third, chicken - pig - fish feed chickens, chicken manure feed pigs, pig manure fermentation after feeding fish, pond mud for crop fertilizers, to increase grain production, pig fish feed cost reduction purposes. Tests have shown that raising 100 chickens a year can increase the production of 100 kg of pork by feeding chicken manure to pigs. The pig manure can increase fish catch by about 50 kg. Together with pond mud as fertilizer, the total profit can be more than 1,000 yuan. Fourth, cattle - fish will be weeds, straw or pasture after nitrification treatment of cattle, cow dung by fermentation after feeding the fish, and then Qingtang mud for farmland fertilizer, under normal circumstances, 2 cows fecal feed 1 mu pond Fish, the annual increase in adult fish 200 kg. 5. The cattle-goats use the characteristics of cattle eating tall grass and sheep eating short grasses. They adopt double-level grazing in turn on limited grassland, first release cows, and later release sheep, which greatly improves the utilization rate and economic efficiency of grass pastures. 6. Cattle-mushrooms-cockroaches-chicken-pig-fish Using the weeds, straw or pasture to feed cows, cow dung for mushroom cultures, use the scraps from the mushrooms to grow the quail, feed the quails to the chickens, and feed the chickens after fermentation. , Pig manure after fermentation of fish, fish pond mud as fertilizer. VII. Livestock - Biogas - Edible Fungi - Pork - Chicken - Pig - Fish Straw After being treated by ammoniation, alkalization or saccharification, livestock is fed and livestock manure and feed residues are used to make biogas or culture edible fungi. Bacteria waste will be bred, and will be fed to chickens, chicken manures will be fed to pigs, biogas residue and pig manure will be raised, fish residues will be used as fertilizer. Livestock - fly maggots - chickens - cattle - fish Manure from manure is artificially fed, maggots are high protein feed for chickens, cattle are fed after chicken manure regeneration, fish is fed with cattle manure, fish pond silt is a quality organic fertilizer for crops . Nine, sheep - pig - fish feeding goats with grass. Goat milk is fed to pigs, and pig manure is used to feed fish after fermentation. Fish pond mud is used as fertilizer. Under normal circumstances, each dairy goat can produce 1.5-3 kilograms of milk per day and can make protein feed for 5-10 pigs.
