Honghu Dashahu Farm located in Jingzhou City, Hubei Province, which is well known for Dashahu, the largest lake in the district. In November 1957, the Jingzhou Prefectural Committee of the Communist Party of China and the Jingzhou Special Administration decided to open a state-owned farm here in accordance with the instructions of the Hubei Provincial Committee of the Communist Party of China. Dashahu State Farm has a total area of 164.7 square kilometers, and governs 8 agricultural branches, one agricultural science institute and one water science institute; a total population of 40,300; agricultural land area of more than 30,000 mu, aquaculture area of 117,000 mu, and the freshwater fish farming industry is prosperous, with an annual output value of 136 million yuan. The aquaculture industry has become the leading industry of Dashahu Farm.
Fish ponds need to clean up the sedimented silt at least every two years to ensure good water quality. Generally, the time for farmers use amphibious excavator to clean up the silt is mainly around the Spring Festival. At the same time, after the sale of aquatic products, the time between the amphibious excavator work of clearing the bottom of the river pond and the work of putting new fish fry into work next year is relatively short.Therefore, local demand for dredging fish ponds is large. Amphibious excavators are also in great demand，and higher efficiency requirements.
There was a state-owned shipyard and a state-owned machinery factory in the Dashahu Farm’s establishment of early days . at that time, it had rich experience and talent reserves in shipbuilding and mechanical processing. At the end of the 20th century, under the demand of the market, the graduate students produced the first amphibious excavator. As soon as the amphibious excavator was launched, it was so easy to be in the market, and the fishpond owners line up to order products, which formed a situation of short supply exceeding demand. In the following years, the local amphibious excavator rapidly developed to about 100. Due to the gradual increase in the number of amphibious excavators and the gradual saturation of the local market supply,amphibious excavator operating under great pressure. Therefore, from 2005, the aquatic excavation industry has gradually entered the national market.,and the main applications include swamps, wetlands, and reclamation conditions.
According to preliminary statistics, as of the end of 2018, local residents have already had about 1,600 Amphibious Excavator, and personal possession of seven, eight or even more than ten is not uncommon in the local area. For this reason, Dashahu Farm is called China’s “land of water digging” by industry customers.
