199 1 year, Lin Shizhu aimed at the shrimp industry and started a difficult business. In the process of starting a business, he was repeatedly hit by the shrimp epidemic, which made him think deeply: shrimp in the sea will not get the shrimp epidemic, so how to create an ecological environment similar to the sea for the shrimp pond? Blue-green algae reproduce under strong light, so they are mainly concentrated in the top layer of water. It is suggested that when there is enough water in flood season, the surface fertilizer water should be discharged, and the water exchange capacity can reach more than 1/3.
At noon on a sunny day, the bottom microporous aerator and the upper waterwheel aerator are started at the same time, which speeds up the exchange of water bodies, accelerates the decomposition and transformation of organic corrupt substances at the bottom, and at the same time brings harmful gases at the bottom to the surface for aeration and escape. In order to achieve this goal as soon as possible, Lin Shizhu began to study the ecological environment of shrimp ponds. Unable to afford a microscope, he borrowed one from a junior high school physics teacher. Without experimental equipment, pots and pans at home will come in handy. In order to observe the ecology of shrimp ponds, he often forgets to eat and sleep. Just observing the diary of biological characteristics, he recorded four thick notebooks,100000 words.
After numerous experiments, from 65438 to 0997, Lin Shizhu finally discovered that two kinds of small organisms attached to seaweed were very important for preventing and treating prawn diseases, and he immediately applied this discovery to aquaculture practice. When the prawn epidemic struck that year, the prawns of other prawn farmers were wiped out, but his prawns were unscathed, making a net profit of more than 50,000 yuan.
Lin Shizhu's technology has attracted the attention of the Municipal Science and Technology Bureau and the Yellow Sea Research Institute. They sent experts to his shrimp pond for research and analysis, and finally gave an appraisal: his technology has obvious effects of promoting growth and preventing diseases, saving artificial bait and reducing production costs, reaching the leading level in China. With this technology, Lin Shizhu made a lot of money, and in 2002, he established an aquaculture research institute with advanced facilities such as water quality testing equipment, covering an area of 130 mu.
After his success, Lin Shizhu will never forget the farmers' desire to get rich. "With many years of experience in shrimp farming, I really understand the ups and downs of shrimp farmers. I must teach them to learn technology and make them rich. " Over the years, Lin Shizhu has taught his research results to villagers, townspeople and even outsiders without reservation. At present, the area of shrimp ponds in Shandong and its surrounding areas using forest-column ecological shrimp culture technology has reached 1.2 million mu, which can increase the income of shrimp farmers by 1.00 yuan per mu every year.
