This newspaper (journalist) has become a reality on the outskirts of kyoto, when it appears that the fish ponds are growing vegetables and flowers. Yesterday, journalists learned from the city aquatic technology extension station that a total of 500 acres of fish pond water had been turned into vegetable fields and gardens in 6 districts, such as hiyayama, tunzhou and haydoun. The plumes, cabbage, celery, lettuce, etc., grow on the water with fish, clean the water quality and save the flowers, vegetables and fertilizers。
Green-oiled celery, empty cabbage, lettuce, floating on calm waters, the underwater fish rises from time to time and travels through the root. Yesterday, journalists were quick to see this new technology at the aquatic technology extension base near the six-cyber bridge on haidambei road。
How can the great-grandfather grow flowers and vegetables in the earth so that they can take root? The technicians at the municipal aquatic extension station explained to journalists that the usual green leaves, such as cabbage, celery, lettuce, and aqueous plants, such as acne, could be installed on water and only a simple floating bed was needed。
Floating beds, by definition, are beds where plants float on water. They are more than one metre long and more than two metres wide and are made up of bamboo, which is covered with long plastic tubes. The seedlings of aquatic vegetables are placed in plastic pipes, with roots immersed in water and branches covered with sunlight. Using root systems to absorb nitrogen and phosphorus in water, young seedlings convert surplus harmful products, waste from aquaculture into nutrients for vegetable growth and spoil it. They also discourage the overproduction of harmful algae and address the frequent problem of eutrophication of water bodies。
In the water where flowers and vegetables take root, harmful substances such as nitrogen phosphorus in water are absorbed into nutrients, so that they are not fertilized and then managed independently, and are less expensive and less expensive. The staff of the municipal aquatic extension station described as most commendable the fact that vegetables grow in water, are not immersed in common vegetables, are not immersed in endemic diseases and do not have to fight pesticides if they are not sick, so they are completely harmless, clean and taste better than normal vegetables。
The technicians told journalists that not only did they not own the land, but they also benefited better. At the test site of the small village in tunzhou district, fish ponds were closed, blocking part of the sunlight, but the production of aquatic vegetables was five times that of the general greenhouse and 20 times that of daejeon. The profit per acre is over $500。
