Aquatic weed planting. Before the crab seedlings are stocked, the method of cutting stems and segmenting rods is used to plant Elophyllum in the ring ditch. Because the inner side of the crab pond ring ditch is very steep, it is only planted on the outside of the ring ditch.
The field is mainly planted with black algae and bitter grass, which is transplanted at the beginning of spring when it sprouts, and the bitter grass is sown after the field is watered. According to the growth and characteristics of aquatic weeds in the crab pond, replanting can be carried out in a timely manner in places with fewer aquatic weeds, and the coverage rate of aquatic weeds in the whole pond reaches about 80%.
