Transplantation skills of aquatic plants in crab pool

Water grass has a very important role in raising crab ponds. In order to create a natural environment for artificially cultivated crabs and increase the adaptability of crabs to the pond environment, transplanting and nurturing water plants has become an important part of pond crab cultivation.

First, choose the variety.

1 According to the superiority of river crabs to aquatic weeds, the type and quantity of transplanted aquatic weeds are determined. Generally, they are submerged plants and emergent plants, supplemented by floating leaves and floating plants.

2 According to the feeding habits of crabs, aquatic plants such as crabgrass, blackleaf algae, and goldfish algae can be cultivated, and other varieties of aquatic plants should be properly transplanted to complement each other, which can improve the water quality of the pond and increase dissolved oxygen in the water. Increasing water transparency has a good effect.

Second, the transplantation method.

1 At the bottom of dry rivers and lakes, the selected bittergrass and black-leaf algae will be transported to the crab pool with a spatula and the soil and grass roots will be transported to the crab pool. The soil will be buried well, and it will grow automatically in the spring and summer.

The black-rooted black algae root system is developed, and each plant is of different lengths, and many stem sections can grow hairy roots. The whole plant was collected, and the roots were packaged in wet clay or phimosa knots and put into the crab pool. After planting once, they could grow every year. Transplanting Vallisneria can also be used to root the roots, and the roots can be encased in mud and put into a crab pool.

3 Collect aquatic weed seeds in late August every year. The fruit of Vallisneria grows on a slender shank and is linear in shape. There are spikes on the ends of the black alga seeds. When harvested, they are dried together with aquatic plants, crumbled and stored, and sowed in the selected crab pond the following spring.

Third, pay attention to matters.

1 In the shallow water area of ​​crab ponds, more emergent plants, such as typha latifolia, reeds, and white peony, should be cultivated. These plants are easy to cultivate and have a high survival rate. Besides having a good effect on improving the water quality environment of river crabs, they can also obtain certain Economy Profit.

2 In the deep water area of ​​crab pond, some submerged plants and floating leaf plants can be properly transplanted, such as leeks, leeks, and water chestnuts. These plants have developed root system and strong vitality, but they cannot be transplanted too much because they will cover the water after prosperously. Affect the pool water reoxygenation, adverse to the growth of crabs.

3 The plants planted in the crab pool can be allowed to grow naturally. Generally, no manure is applied, and appropriate chemical fertilizers can be applied. Aquatic plants can absorb ammonia nitrogen in the water, dilute the water's fatness, increase dissolved oxygen and transparency in water, meet the needs of crab growth and development, and improve the meat quality of river crabs.
