This kind of plane planting form has 6 years of strength. The first reason is that because of Pak Pak Tin fish farming and duck rearing, farmers can only use low-toxic pesticides. Therefore, Zhuo Bai has become a pollution-free vegetable and his moral character has also improved. The second is that this kind of plane breeding culture has significantly improved the use of land and water capital. Third, fish and ducks have eaten weeds in the field, effectively delivered grasshoppers, and facilitated the development of beneficial insects (long green planthoppers, locusts, etc.) at the base of the white plant, thereby aggravating pests and weeds, eliminating the use of pesticides and dosages. Fourth, duck dung is a good feed for fish. Fifth, ducks are tender, delicious, and expensive. Sixth, it has significantly improved the economic efficiency of Bai Tian.
Lot selection is basically a choice of areas that are conducive to flood control, water conservancy and irrigation, good soil, deep soil, and fertile soil.
The ridge type planting width is 1.2 meters wide, the width is 40 centimeters, and the depth is 25 centimeters to make the ridge ridges. The mud is evenly spread on the surface of the ridge, and the 1000-1300 vines per acre is better. Affecting fish farming, over-ripping affects yield. Accepting wide and narrow lines can create a useful space for fish development. Dig 2 fish ponds with a length of 2 meters and a depth of 1 meter per acre. The fish should be in the shape of “10†or “well†in the same fish pit. Do a good job of avoiding water ditches, flood prevention trenches, and reinforcements. Drainage and irrigation.
Fair-fighting fry and control of superstitious breeding In late March, 350 eel seedlings per mu, 50 grass carp were good, and fine green arborescens and kazhouping were used as help feeds, with wheat bran, rice bran, bean cake, bean curd residue, Cakes, etc. for the fine material, fixed, quantitative, punctual feeding (according to 20 minutes after eating), when the fry put, apply 5% saline to disinfect the fish body, after stocking often review the water snake harm, once invented, Kill in real time.

Topuzin et al. When the application of pesticides, there should be 3 cm deep water, and should not be too shallow. Basically, 2000 kg of inorganic fertilizer is applied per acre before emergence. Basically, 50 kg of common fertilizer or compound fertilizer is used for Mushi, and the time of application is March. In the middle and late, in the future, we will see the quick-effect fertilizer Miao Shi, in the fertilization only stick to the fish ditch water, after 2 days and then irrigation, in order to avoid the formation of adverse effects of fish diet.
In early July, duck raising technology was purchased for male ducklings (due to the fact that ducks are not raised by professional households, so the male ducklings are extremely low in cost).
