First, choose a breeding farm
1. Choose a sea area where the tide is small and the flow is unimpeded, and freshwater is injected into the middle-tidal zone as a breeding ground.
2. The tidal flat should be flat and the windy season should have a stable coating surface. Generally, it will not be covered with silt.
3. The coating quality is better with argillaceous or slightly sand mixed, moderate mud and soft hardness, tight coating structure, no hole and thin mud layer in the middle, good water retention performance.
4. In spring and autumn each year, diatoms are often propagated and propagated on the coated surface, providing abundant foodstuffs.
Second, the construction model
1. The size of Putian can be determined according to the topography and direction of the traffic. The general length is 50 meters, width is 3 meters, and a drainage ditch is excavated at intervals of 1 meter. Drainage ditch is opened around the paddy field. The ditch width is 20 cm to 25 cm and the depth is 15 cm to 20 cm.
2. Construct a dwarf embankment 30 meters to 40 meters above the paddy field. It can avoid flooding tides in flood fields or flooding in the summer and flooding the fields in Putian.
3. Tillage mulching is an important measure to improve soil quality, eliminate predators, increase the rate of burrowing of seedlings, and remove toxic substances such as hydrogen sulfide in the soil. It is required that in the winter or spring, or within one month to two months before the seedlings are planted, the paddy field should be thoroughly deep-turned 1 to 2 times with a tumble coater, and the depth of ploughing should be about 40 cm to 50 cm; Ping, built a standardized model.
Third, carefully selected seedlings
1. According to the breeding season, the seedlings are divided into "Dong Zi", "Haru Zi" and "Xia Zi". With Dongzi's best constitution, the survival rate is high; the spring child is the second; Xiazi is the worst. Choose the complete, glossy, full-grained, uniform-sized, fresh and lively seeds. The method to test the quality of the seedlings: a little shaking or slap the seedlings by hand, and the double shells of the seedlings are good seedlings, and the survival rate can reach 90% or more.
2. The shipment of seedlings must be made to grab time, catch up with speed, and install light shipments. Try to shorten the transit time and strive to finish within 24 hours. Try to arrange it on a sunny day. The temperature is suitable for 10°C to 15°C.
Fourth, timely sowing, reasonable sowing
1. The end of sowing should be completed before and after Qingming.
2. The seeding rate per acre seedlings should be determined according to the individual seedling size, physical strength, coating quality, thin skin, and diatom breeding on the surface. Should be mastered in the specification of 3000 to 6000 grains per kilogram of seedlings sowing 5 kg to 125 kg per acre.
3. Should pay attention to sowing uniform, homogeneous, enough. If seedlings are found, they should be promptly filled in to ensure the planting density.
4. Seed sowing within half an hour before high tide to avoid loss of seedlings because they are not washed away by the tide.
Fifth, strengthen the coating management
1. The seedlings that have just been planted have a shallow lair, and there should be special persons to inspect the surface, strengthen the management of the coating, and prevent humans from trampling or birds from feeding.
2. To clear the channels in time, eliminate the water in the fields, keep the channels in the fields between the fields open, smooth the flow, and cover the surface with no stagnant water, so that “the tides come at the same time and the tides retreat at the same timeâ€.
3. Endanger the lice many predators, mainly arrowheads, blue crabs and ducks, etc., should be thoroughly removed from May to October once a month, you can use 1% sodium hydride solution sprayed fields at the Sakata water.
6. Timely harvesting has a certain degree of regularity due to the growth of scorpions. Timely harvesting is crucial for capturing high sorghum production. According to observations, the most fat season of the year is from late May to mid-June. At this time, the open-coated picks are of good quality and high yield.
Efficient mode of breeding
The wolfberry, commonly known as wolfberry fruit, is a seafood shellfish, and is one of the important varieties of marine aquaculture in the two provinces of Zhejiang and Zhejiang. It occupies a large proportion in the production of marine aquaculture. The oyster shell is rich in flesh and has a delicious taste. It is a popular aquatic product and has a broad sales market. Low breeding cost, short cycle time, high yield, high yield, easy management, and stable output are good roads for poverty alleviation in the coastal areas.
