This three-dimensional planting mode has six major advantages. First, due to Ling Baitian fish farming and duck rearing, farmers can only use low-toxic pesticides, so that white rice becomes a pollution-free vegetable, and the quality is also improved. The second is that this three-dimensional planting technology has significantly improved the utilization of land and water resources. The third is that fish and ducks eat the weeds in the field, ineffective delivery and white base pests (Lark green planthoppers, locusts, etc.), thus reducing pests and weeds, and reducing the number and amount of pesticides used. Fourth, duck dung is a good feed for fish. Fifth, ducks are tender, delicious, and expensive. Sixth, the economic benefits of Baitian are obviously improved. Lot selection is based on the selection of areas that are conducive to flood control, water conservancy and irrigation, and deep and fertile soil. The ridge and furrow type width and width are cultivated according to a width of 1.2 meters, a width of 40 cm and a depth of 25 cm to make a ridge ridge, and the mud in the groove is evenly laid on the surface of the ridge. Affecting fish farming, over-ripping affects yield. The use of wide and narrow lines can create a favorable space for fish growth. Dig 2 fish ponds with a length of 2 meters and a width of 1 meter and a depth of 1 meter for each acre. The fish communicates to the fish pit to have a “10†shape or a “well†shape, do a good job of avoiding ditch, reinforce the flood ditches, and increase the height of the fields. Drainage and irrigation freely. Reasonably place fry and master scientific rearing. In late March, 350 catfishes per acre and 50 grass carp are suitable. Fine green arborescens and kazhouping are used as auxiliary feeds, with wheat bran, rice bran, bean cake, bean curd residue, Cakes, etc. for the fine material, fixed-point, quantitative, regular feeding (take 20 minutes to finish the prevail), when the fry put, use 5% salt water to disinfect the fish, after stocking, always check the water snake damage, once found, Timely kill. Before and after the end of the year, field fish can be harvested and listed in batches. At this time, the fish tail weighs 0.25 kg to 0.5 kg, and the grass carp weighs about 1.25 kg. The rational use of fertilizers and pesticides is a guarantee for the quality of fish and fish and the safety of fish and ducks. Fresh water is often used for nourishing (forbidden use of pesticides that are highly toxic to fish and ducks), and the use of pesticides such as Bt, Shian, imidacloprid, buprofezin, wolfberry fruit, etc. is used to control pupa pests. Triadimefon and carbendazim are used to prevent and treat diseases and pesticides. Topuzin et al. In the application of pesticides, it is necessary to have about 3cm deep water, which should not be too shallow. On the basis of 2,000 kg of organic fertilizer applied per mu before emergence, about 50 kg of special fertilizer or compound fertilizer for Mushi, the application time is March. In the middle and late, after seeing the quick-effect fertilizer Miao Shi, only keep the fish ditch with water during fertilization, and then irrigation after 2 days to avoid adverse effects of fish food. Duckling technology is purchased in early July. Male ducklings (due to the fact that ducklings are not raised by male ducks, the cost of male ducklings is extremely low). Ducklings are kept at home for two weeks to improve their living ability. After that, it can also prevent rat damage. The stocking density is 12 to 14 per mu.
