Asparagus "grows" on the surface of the water

Patches of green vegetables grow not in the vegetable field, but on the surface of the fish pond. Beautiful and handsome men from the city row bamboo rafts, picking in the vegetable garden on the water. This poetic scene is not a legend, but a scene at the Baqu River aquatic vegetable base in Wushan Town, Wangcheng District, Changsha, Hunan Province. "in May this year, the special equipment for growing vegetables on water, which I developed and invented, was patented by the State intellectual property Office." Fu Zhenjian, 45, said excitedly. Fu Zhenjian is a farmer in Wushan town. a few years ago, he contracted a fish pond of more than 20 mu, but the water discharged into the fish pond turned black and smelly because the water discharged into the fish pond was so fat that the nearby villagers had a great opinion about it. Fu Zhenjian thought that if only there was a way to purify the water quality of the fish ponds. At the beginning of last year, treasure inspection had a whim: why not plant vegetables that need to absorb a lot of water in fish ponds to purify the water quality? Using floating boards such as plastic materials and foam, he designed 100 sets of special equipment for growing vegetables on water, which was composed of floating boards, rods, and nets, and asked local farmers to plant seedlings in more than 20 mu of fish ponds to grow aquatic vegetables. What people did not expect was that in June of that year, Fu Zhen checked that the hollow vegetables and baby vegetables planted on the surface of the fish ponds grew stalks, fat leaves and green leaves, and had a good harvest. Fu Zhenjian said that the roots of water-grown vegetables and other vegetables must grow in water and can absorb nutrients in the water without artificial fertilization, and there is no need for weeding, watering, spraying pesticides, and so on. "now the water in the fish pond has become clear, it doesn't smell, and the villagers don't complain to me anymore." Fu Zhenjian said. "can people eat vegetables grown on dirty water and smelly water?" In the face of doubt, Fu Zhenjian put out her own inspection report on aquatic vegetables, which was issued by the agricultural department, which showed that all the indicators reached the edible standard. Fu Zhenjian said: "some of my aquatic vegetables are used to raise pigs, which not only saves feed costs, but also makes tender meat soup fresh after pigs are slaughtered and listed."
