Winter and spring planting of Elodea shrimp and crab is effective

Elodea is native to the Americas and is a high-quality, fast-growing, high-yielding submerged plant. It is known as a submerged plant. Its advantages are: 1. Adaptable as long as no ice on the water can be cultivated, can grow above 5 °C, in the cold winter can be vegetative winter, when Vallisneria, rotundi Hydrilla has not yet germinated, the grass has a lot of growth. 2. High-yield planting of 1 kg of Elodea nutrient herbaceous stems in autumn/winter or early spring, and a special grass pond can produce about 100 tons of fresh grass that year. 3. Nutrient-rich Elodea was 8.23% dry matter, 2.1% crude protein, 0.19% crude fat, 2.5% nitrogen-free extract, 1.52% crude ash, and 1.9% crude fiber. According to the demonstration of the cultivation of crab farmers, Elodea is very effective in planting water on the surface of shrimp and crab aquaculture. The aquatic grasses grow well in the ponds. The shrimps and crabs grow well with less disease and good quality. Elodea can be used as a high-quality green feed for shrimps and crabs. Because of its strong regenerative ability, it can be naturally recovered quickly in the pond after being eaten by shrimps and crabs. It is also a good place for shrimps and crabs to inhabit, hide and clam shells, help to shell, avoid the enemy and maintain a good body color.

Elodea is cultivated by the method of transplanting grass stems, which is generally carried out in winter and spring. The winter planting needs to be done after the shrimps and crabs are caught, and the pool water is drained so that the bottom of the pool is frozen and exposed to sunlight for a period of time. After that, the lime and tea seed cakes are used for disinfection; after the spring planting, the crab species should be raised in advance with a net cage. In the corner, when the plants grow to 15 cm or more, let them go. Otherwise, the sprouts that survive the planting process can be eaten by the crab species, or they can be cut off by the crabs, or even uprooted. The planting method is: cutting the grass into 10 centimeters of stems, like a rice plant, inserted into a pool of sludge in a bundle. The spacing of the rows is 20 centimeters and 20 centimeters, and some blank belts are reserved for future supply. As a space for activities, the crabs are kept in the initial stage to maintain a water level of 30 cm. After the water plants have covered the whole pool, they gradually deepen the pool water.
