Crayfish cultivation pond water planting method

Growing a certain proportion of aquatic plants in aquaculture water plays an important role in crayfish farming. For transplanting aquatic plants in crayfish breeding ponds, it is necessary to take care of floating plants, submerged plants, and emerged plants, and maintain the corresponding proportions. There are many methods for the cultivation of aquatic plants, and different cultivation methods should be adopted according to different aquatic plants.

1, planting method: This method is generally carried out before stocking shrimp. Shallow irrigation of the first pool of water, the turfgrass, such as the black-green algae, Elodea, etc., will be cut into small pieces of 15-20 cm and evenly inserted into the bottom of the pool. There are more silt in the bottom of the pool, which can be planted directly; the bottom of the pond is hard and can be planted before loosening the sediment.

2, into the law: Ling, water lily and other floating leaf plants, can be used directly after the soft mud tightly thrown into the pool so that roots and stems grow in the sediment, leaves floating in the water. It is also possible to dig up the bulbs of Vallisneria in the ditch around March of each year and throw the mud into the pond.

3. Transplanting method: Transplanting plants such as white peony root, arrowhead mushroom and other emerged plants. The transplanting position is in the shoal at the edge of the pool and requires the roots of the seedlings to enter the mud 10-20 cm. 30-50 trees can be transplanted per acre.

4. Breeding method: Floating leaf plants such as duckweed can be harvested at any time according to need, and can also be cultivated in the pool with a bamboo pole, straw rope, etc. at a corner. As long as the water maintains a certain degree of fat, they can all grow well. If the water is not fat, a small amount of chemical fertilizer can be used to sprinkling and promote its growth and development. Aquatic peanuts have strong vitality and should be transplanted in small quantities to supplement the inadequacies of other aquatic plants.

5, seeding method: Planting Vallisneria sowing method. The water level at the time of sowing is controlled at 15 cm. The bitter grass seeds are first soaked in water for 1 day, and then the soaked fruits are crumbled and the small seeds in the fruits are picked up. Then add about 10 times the amount of fine sandy loam soil, and mix with the seeds and sow. 15 acres of water use 1 kg (dry weight).
