Its technical essentials are as follows:
1, lot selection is the basis. We must choose a lot of land that is conducive to flood control, good irrigation and drainage conditions, and deep and fertile soil.
2, 垅畦 style wide and narrow cultivation. According to the width of 1.2 meters wide, 40 cm wide, 25 cm deep to make a good cocoon, the ditch slurry evenly spread on the surface, per acre planted white 1000-1300 bundles is appropriate, too dense affect the fish, the impact of excessive White production. 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 per acre. The fish communicates to the fish pit to form a "10" or "well" shape. Do a good job of avoiding the ditch and flood control ditch, and then reinforce and raise the field hoe, so that you can run freely.
3. Reasonably put fry and master scientific breeding. In late March, 350 catfishes per acre were fed, and 50 grass carp fish were suitable. Fine green arborescens and kazhouping were used as supplementary feeds, and wheat bran, rice bran, soybean cake, bean curd residue, and cabbage cake were used as the concentrate feed. Fixed-point, quantitative, and timed feeding (takes 20 minutes to finish). When the fry is released, use 5% salt water to disinfect the fish. After the fish is stocked, it is necessary to check the water snake for damage. If it occurs, kill it in time. By the end of the year, field fish can be harvested and listed in batches. At this time, squid tail weighs 0.25-0.5 kg and grass carp weighs 1.25 kg.
4, the rational use of fertilizers, pesticides. This is the guarantee of high quality and security of fish and ducks. Fresh water is often used for nourishing (forbidden use of pesticides that are highly toxic to fish and ducks), and Bt, Shian, imidacloprid, buprofezin, wolfberry fruit, etc. are used for the prevention and control of pupa pests. Triadimefon and carbendazim are used to prevent and treat diseases and pesticides. , Topbujin and so on. When the application of pesticides, there should be about 3 cm of water, which should not be too shallow. Based on 2000 kg of organic fertilizer applied per mu before emergence, about 50 kg of special fertilizer or compound fertilizer is applied in Mushi, and the fertilization time is in March. In the later days, after seeing Miao Shi applying the quick-acting fertilizer, only keep the fish ditch with water during fertilization, and then re-irrigation after 2 days so as to avoid adverse effects caused by fish-fed fertilizer.
5, duck technology. In early July, male ducklings were purchased and first kept in the home for half a month to improve their living ability. After being stocked in Baitian, they also prevented rat damage. The stocking density is 12-14 per mu. Before the ducks are stocked, the center of the field must use a shelter of about 3 square meters for the ducks to use during heavy rain and rest in the evening. If a small area is stocked, Tian Hao must block it around. In the later period, some duck feeds can also be put in place. Ducks are harvested in mid-to-late October, when the ducks weigh only 1-1.25 kg.
The new technology of co-incubation of white rice, fish, and duck is a highly efficient, three-dimensional, and new-type breeding mode, and has six major advantages. The first reason is that due to fish farming and duck rearing in the white fields, farmers are forced to use low-toxicity and low-residue pesticides. This makes white rice a pollution-free vegetable and its quality has also improved. The second is to significantly increase the utilization of land and water resources. Third, fish and ducks eat grass weeds, ineffective delivery and white base pests (long green planthoppers, aphids, etc.) to reduce pests and weeds, and reduce the number and amount of pesticides used. Fourth, duck dung is a good feed for fish. Fifth, the "wild duck" is tender, delicious, and high in price. Sixth, the economic benefits of Baitian are obviously improved.
