Method for managing aquatic plants in pond

Abstract

The invention discloses a method for managing aquatic plants in a pond. The method comprises the following steps that (1) the coverage area of the aquatic plants is kept accounting for 50-60% of the whole pond; (2) different aquatic plant categories are matched at a culture pond opening; and (3) proper oxygenation and bottom change are conducted on the culture pond, and a culture water body is kept balanced. Management of the aquatic plants in the pond is reasonably optimized, comprehensive regulation and control are conducted from the aspects of aquatic plant coverage area, aquatic plant category matching, water body management and the like, ecological balance in the water body can be well achieved, different aquatic plant variety matching planting methods are provided according to different water levels of the culture pond, reasonable matching is utilized, and the water level is adjusted to the greatest extent, a thicker habitat is more effectively provided, a rich material basis and an excellent ecological environment are provided for fish and shrimp cultivation in the pond, the positive effect on water purification is also achieved, and the cultivation requirement of the pond, especially an intensive culture pond opening, is met.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for managing aquatic plants in ponds. Background technique [0002] In the process of aquaculture, aquatic plants are an indispensable and important ecological factor. Aquatic plants are not only places for aquatic organisms to inhabit and avoid enemies, but also become bait for some fish and shrimp. They are rich in nutrients, rich in protein and crude fiber , vitamins and minerals, good palatability, fast digestion and absorption, can save concentrated feed, reduce feeding costs, and promote the growth of fish and shrimp. Not only that, aquatic plants can also purify water quality, increase dissolved oxygen in water through photosynthesis, and provide a better environment for the growth of aquatic organisms. [0003] However, the growth state of aquatic plants is affected by various factors such as water temperature, water quality, and fertility, and i...

Problems solved by technology

[0003] However, the growth state of aquatic plants is affected by various factors such as water temperature, water quality, and fertility, and it is prone to stagnation or even rot. Only by maintaining the vitality of aquatic plants in ponds during the high temperature season in summer can we ensure that they can still survive in harsh environments such as high temperatures. Normal growth is not easy

[0004] At present, farmers are faced with a variety of complex problems in the daily management of aquatic plants. The daily management of aquatic plants also tests the farmers' ability to deal with details and perseverance, including frequent top dressing, Multiple applications of water quality regulators and other operations have greatly increased the operational difficulty and labor costs of aquatic plant management. Therefore, it is of great significance to aquaculture to rationally optimize the planting management and maintenance methods of aquatic plants in ponds.
