Peng Zexi grows fast and has a delicious flesh. The stocking in Dianchi Lake can make full use of biological resources in the water and increase the overall efficiency of Dianchi Lake. Generally, 2000 kilograms per mu can be produced, 200 kilograms can be produced in Pengze, and the net profit can exceed 3,000 yuan. Now the main technologies are introduced as follows:
I. Conditions of Pengze Dianchi
Dianchi Lake requires that the bottom of the pool is flat, the pool is solid, the drainage is convenient, the water quality is good, no leakage, and the area is 1-5 acres.
Second, the transformation of Dianchi Lake
Dianchi Mushi manure 2000 kg base fertilizer. After the leveling, add appropriate amount of water and mix well with shovels to keep 30-40cm of silt in the tillage layer. After 10 days, the mud becomes hard to excavate the ditch and fish pits. The purpose is to provide the fish with high temperature, shallow irrigation in Dianchi, and top dressing. Hide and feed and observe their eating and activities. The ditch is dug into a “field†shape or “mesh†shape. The ditch is 50-60cm wide and 30-40cm deep. Several fish pits are digging properly at the ditch intersection or around the paddy field. The pit is 0.8-1m deep and excavated. The dirt removed from the ditch and pit is used to raise the height of the turbidity pond.
III. Planting and feeding fish
In mid-April, 160-180 kilograms of high quality alfalfa species were planted in 10-15cm soil and 20cm of water was poured into the mud. After half a month, Pengze oyster species could be added. Pre-deployed with 3% -5% saline immersed for 5-10 minutes, stocking density depending on the feed supply conditions, the general mu of 8-10cm squid species of 1000 tail.
Fourth, daily management
(1) Feeding Bait is selected as a feeding point and prilled pellet feed is fed twice a day. The daily feeding amount accounts for 1%-3% of the total body weight of the fish.
(2) Water-feeding fish and fish ponds should take into account the reasonable adjustment of water depth to facilitate the normal photosynthesis and growth of alfalfa. In the initial stage, attention should also be paid to the patrol pool to see if there is any kind of phenomenon (the main reason is that the pressure is too shallow or the water is too deep or the squid is released early). Shallow squat arches, generally the depth of the pool is kept between 30-50cm, and it is properly adjusted according to the situation.
(3) Topdressing and regulating water quality Topdressing can promote the good growth of earthworms and cultivate natural fish food. The amount of topdressing fertilizer is 200-300 kg of manure per mu, and it is necessary to pay attention to the observation and adjustment of water quality to keep the pool water and fertilizer live and tender. .
(4) Anti-fish disease In the epidemic season of fish diseases, about 10 ppm of quicklime is splashed around the ditch and fish pit every 20 days to prevent fish diseases or to feed baits, and actively prevent and treat fish diseases.
