1, culture conditions. The cultivation of sea melon seeds is generally carried out in coastal areas, but the areas with relatively small waves and slow water flow should be selected, followed by soft sediments at the bottom of the farm. Sea melon seeds are suitable for growing in an environment where the water temperature is between minus two and thirty-five degrees and the water content is between seven and thirty-two percent. Finally, it should be noted that farms should choose areas with pollution sources to ensure the water quality of the farming areas.

2. Farm repair. Generally, the breeding farms of sea melon seeds build rivers and reservoirs in coastal areas and adopt the principle of low dam water storage for breeding. Farms should build dams, ditches and water outlets, the area should be determined according to the number of farms, and farms should be built according to local topography. Dams are generally 40-50 cm, trapezoidal, 80-90 cm wide at the bottom and 40-50 cm wide at the top. Build ditches around the farm with a depth and width of 30-40 cm. Shuikou is built in the estuary, which can reasonably control the water level. Finally, the bottom of the pond on the farm was trimmed and raked.

3. Clear pond management. Before sowing melon seeds, we need to clean the pool on the farm. Before sowing seedlings, sprinkle appropriate amount of quicklime or bleaching powder in the pond to clean up the organisms harmful to the survival and growth of melon seeds in the pond. Cleaning the pond should be done on a sunny morning, so it will be cleaned more thoroughly. After disinfection and sterilization, the water in the pond is discharged, and finally the pond is leveled.

4. Scientific sowing. Because of the climate difference in different regions of China, the sowing time of sea melon seeds is also different. But most areas are held in May, June and November every year. Sowing is usually carried out in the dry season. When the tide is dry, the water in the pond is drained, then the sea melon seeds are evenly scattered on the water surface of the pond, and then an appropriate amount of water is added for cultivation. Generally, 300,000-400,000 plants can be planted per mu. Try to choose bigger ones to reduce the number of seedlings.

5. Development management. In the breeding process of sea melon seeds, the most important thing is to control the water level, prevent collapse, prevent floods and adjust salinity. Change the water regularly during the breeding process, check the growth of sea melon seeds at the same time, and trim and clean the pond regularly. Clean up the remaining natural enemies in the pond in time, control the water level reasonably, lower the water level in spring and autumn, and raise the water level in Xia Dong. The second is to check the state of the dam and repair it in time. Finally, pay attention to weather changes and prepare for disaster prevention in time.
