Background
In the prior art, aquatic plants are rich in nutrition and contain substances such as protein, fat, cellulose and the like in the aquatic product cultivation process, and are natural baits for aquatic organisms such as fish, shrimp, crab and the like. In water, the aquatic weeds can also purify water quality and regulate water temperature, and are used for adhering, unshelling and concealing crustaceans such as shrimps and crabs, so as to avoid good places of mutual injury.
The growth and distribution of aquatic weeds are affected by environmental factors such as illumination in water, mineral elements and substrates, most lakes currently lack aquatic weeds, and most lakes have difficulty in recovering aquatic weeds due to the substrates (anaerobic or hard substrates), transparency of water bodies, large fluctuation of water levels and other factors, so that in fish, shrimp and crab ponds, grass seeds are usually sown to meet the requirements of aquatic weeds for cultivation. However, a certain time is needed for growing grass seeds, farmers need to wait for the aquatic grass to grow to a certain size to put seedlings in for cultivation, and thus the cultivation period is influenced; in addition, before the first-stage fishing of the fish, shrimp and crab seedlings, the aquatic weed at the bottom of the pond is cleaned or pulled out, so that part of the water in the pond is required to be discharged, the aquatic weed is required to be manually immersed into the bottom of the pond for cleaning, and manpower, material resources and time are consumed.
