“Only good water and soil can produce good agricultural products, and on this point, some government functional departments and even agricultural experts have not given sufficient attention, or rather, have been unable to face it squarely. After all, soil pollution has become an intractable problem in the process of industrialization and urbanization.” As soon as Liu Weichao spoke, he commanded a new level of respect.บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
Liu Weichao comes from Hong Kong and holds a Ph.D. in biology. Perhaps because of his professional background, he has an innate sensitivity to food. Having lived in the mainland for many years, he was perplexed by the repeatedly exposed food safety issues, and the idea of engaging in organic agriculture took root. First, it would solve the eating problems of his own family and friends around him; second, it would allow him to conduct beneficial attempts and explorations combining his professional expertise, and he took great pleasure in it. Several years ago, he accidentally became acquainted with some large-scale growers and also took a fancy to these several hundred mu of “feng shui treasure land” in the Doumen Lianzhou Ecological Park. After more than a year of effort, Liu Weichao's vegetable base has already formed a certain production scale, supplying more than 3,000 kilograms to the urban area every day, and the base has already acquired a certain production capacity. “Food safety has attracted much attention, and quite a few work units have long-term ties with us, ordering organic vegetables,” Liu Weichao said.บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
The reporter saw on site that the 300 mu of vegetable land Liu Weichao rented had been divided into strips and plots, neat and orderly. In the fields, cucumbers, tomatoes, and green beans—the vegetables in season—were the most abundant. “Most of the time, my workers and I eat breakfast right in the fields. Cucumbers and tomatoes picked on the spot, washed with canal water, become a healthy breakfast.” On a fine day, flocks of sparrows skimmed low like small airplanes, startling a group of partridge chickens frolicking in the wild fields. “They come for the tomatoes and peck and ruin quite a few every day. But it doesn't matter. I quite like them. Tomatoes, cucumbers, and so on—I let them eat as they please. The pecked ones can be fed to the chickens, so nothing is wasted.”บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
In recent years, while continuing his environmental protection business, Liu Weichao has devoted much time and energy to cultivating his organic vegetable “experimental field.” “Actually, what takes the most effort is not the planting stage, but soil improvement,” Liu Weichao said. This piece of farmland, designated as the Doumen Lianzhou Ecological Park, is located within a water source protection area, and its ecological foundation is already quite good. It had previously also served as a supporting base for the city's vegetable basket project, growing various vegetables on a large scale. Liu Weichao's entry once again improved the water and soil from the source. “There are many methods available for maintaining and improving water and soil. In order to maintain good soil and fertility, we have mainly carried out planned crop rotation, and also adopted some physical methods, such as raising earthworms, applying probiotics, and so on, to protect this fertile farmland well and let it play a greater role.”บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
During the interview, the reporter learned that Liu Weichao recently built a “mushroom spawn shed” at the base and introduced several varieties of mushrooms for experimental cultivation. He told the reporter that mushroom cultivation is also the simplest and most effective method for testing soil. For example, termite mushrooms will not grow in polluted areas. Therefore, during the experimental stage in the cultivation shed, we continuously adjusted and improved the culture medium, using microbial technology to effectively degrade and improve the soil.บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
Liu Weichao's ideal is to practice ecological agriculture in the true sense, produce organic agricultural products, form a scale, promote cultivation among surrounding farmers, and ultimately also develop agritourism. In addition to planting, Liu Weichao has built a rabbit farm and a chicken coop at the base, raising an initial batch of 800 partridge chickens. At the same time, he also tried raising several dozen geese and ducks. “My entire base uses no chemical fertilizers or pesticides, so there are especially many insects. Pest control mainly relies on physical methods, using natural enemies to maintain ecological balance. Letting these poultry roam freely is to have them catch insects,” Liu Weichao said.บทความมาจากFOFCC-http://fofcc.org.cn/th/11333/
