After a period of large growth of aquatic grasses, the content of carbon dioxide in water decreases, the background values of carbonate and bicarbonate decrease, and the buffering ability is poor, resulting in alkaline water. In addition, a large number of water weeds decay beyond the capacity of nature, unable to decompose in time, resulting in the growth of bacteria, dissolved oxygen in the water is also greatly reduced. And floating weed is likely to clog the pump, causing damage to equipment. Excessive concentrations of aquatic plants, such as water hyacinths, can also make it difficult for boats to move.
But weed cleaning is difficult. When the water temperature is high, it can grow more than 10 centimeters in a day. Some water weeds are completely useless with herbicides, and artificial fishing is also slow, completely unable to keep up with the growth rate of water weeds. Therefore, the adoption of water grass harvesting boats has advantages in fishing and transporting water weeds. Comprehensive calculation is more economical than artificial salvage, saving time and effort, high efficiency.
Mowing boat, as the name suggests, is a kind of modern water grass, water hyacinth harvesting and transportation equipment suitable for small and medium-sized lakes, rivers, artificial lakes and other urban garden scenic spots.
Influenced by global economic weakness and excess tonnage, China's grass cutter industry is facing a difficult period of operation and survival for more than 30 years. It is widely believed that only further transformation, upgrading technology and improving design will help the industry out of its difficulties.
Although China's lawn cutter industry has made great progress in recent years, it still needs to be further improved in terms of design, shipbuilding quality and after-sales service. This crisis is also a good time for the industry to reflect on and look for shortcomings. Many ship supervision engineering and ship design experts believe that the lawn mowing ship industry continues to be depressed and the banking industry tightening financing to the shipbuilding industry, a new round of reshuffle is inevitable, half of the shipyards or be merged and restructured, and the research and development ability is weak, slow transformation of the lack of capital enterprises are bound to become the object of elimination, lawn mowing ship pay attention to the use of new technology and the development of new ship type, is the only way to save the shipping industry decline.
