Bai Bai, fish and duck co-culture technology

There are five major advantages in the technology of co-inoculation with white fish, fish, and duck: First, after fish farming and duck rearing in the white field, farmers are forced to use low-toxicity and low-residue pesticides. This production of alfalfa can be used as a pollution-free vegetable, and the quality of white meat can be reduced. The second is to improve the utilization of land and water resources; the third is to fish, ducks eat food weeds in the field, ineffective childbirth and white base pests (such as long-green fly locusts, locusts, etc.), reduce pests and grass Harmful, reducing the number and amount of pesticides used; Fourth, duck dung can be used as a feed for fish; Fifth, the production of "wild duck" tender, delicious, high prices. The technical essentials are as follows:

Selection of plots: It is necessary to choose lands with good irrigation and irrigation conditions and deep and fertile soils for joint breeding.

Cultivation method: According to the width of 1.2 meters wide, 40 cm wide, 25 cm deep to make a good hoe, the mud dug out in the ditch evenly spread on the surface, per acre planted white 1000-1300 bundle is appropriate, over Closeness affects the fish culture, while thinning affects the white yield. Wide and narrow lines are used to cultivate white fish, which can create a favorable space for fish growth. Dig 2 fish ponds with a length of 2 meters, a width of 1 meter, and a depth of 1 meter per acre. The fish communicates to the fish pit and forms a “10” or “well” shape. Do a good job of avoiding flood ditch, flood control ditch, reinforce and raise the field hoe, and be able to discharge freely.

Frying seedlings: In late March, 350 catfish seedlings and 50 grass carp seedlings are suitable for each acre. Fine green larch is used as an auxiliary feed for fish feed, and wheat bran, rice bran, bean cake, bean curd residue, and cabbage cake are used as the concentrate feed. Set point, ration, timing (takes 20 minutes to finish) feeding. Fish were disinfected with 5% saline before the fry was released. After the fry are stocked, they should always inspect the water snakes for harm. Once discovered, they must be killed in time. Before and after the end of the year, field fish can be listed in batches.

Reasonable use of fertilizers and pesticides: This is the guarantee of the quality of fishy whites and the safety of fish and ducks. For the control of cockroaches, pests such as Bt, Schneillin, imidacloprid, buprofezin, and Tribulus terrestris can be used. For the control of alfalfa disease, triadimefon, carbendazim, thiophanate and other pesticides can be used. When applying pesticides, it is advisable to keep the depth of surface water about 3 centimeters, which should not be too light. Before the emergence of 2000 kilograms of organic fertilizer per acre basis, Mushi special fertilizer or compound fertilizer about 50 kg, fertilization time in mid-March, after seeing Miao Shi applied fertilizer.

Duck raising technology: In early July, male ducklings were purchased, and they were raised at home for half a month to improve their living ability. Then they were stocked on the farmland in Pak Pak Tin to prevent rat damage. The duck density is preferably 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. During the later period of cultivation, some duck feed should be fed properly. Ducks can be marketed in mid-to-late October.
