Soilless cultivation techniques of sprouts and vegetables that can be used as bonsai
Recently, a group of volunteers from Nanjing Agricultural University walked into the bell tower community of Twin Towers, bringing residents the soilless cultivation technology of sprouts, which is the new favorite of the dining table, setting off a "green whirlwind" of organic life in the community.
A plate, a handful of seeds, sprayed with water, put on the balcony for a week or so, you can harvest fresh organic vegetables. "choose a handful of full-grained vegetable seeds, soak them in water for about 20 hours, then take them out, sprinkle them evenly into a plastic plate covered with gauze, cover them with gauze, and spray it with water every day. In about two days, the seeds will germinate and they will be harvested in about a week. " At the scene of the event, pots of "cute" sprouts earned enough attention from the residents. The volunteers also passed on the cultivation techniques of sprouts to the residents at the scene.
After a vivid explanation, the residents are rubbing their hands one after another, trying to cultivate a pot of sprouts of their own. Qian Rongrong, a resident who is already a flower lover, was pleasantly surprised by this activity: "for those of us who live in the city, eating our own vegetables seems to be an impossible dream." After participating in this activity, I learned to cultivate sprouts without soil. in the future, I will not only be able to eat my own vegetables, but also watch the seeds germinate and grow slowly, and enjoy the joy of being close to the green countryside. "

At present, the common varieties of sprouts are black bean seedlings, soybean seedlings, hollow cabbage, Turnip Sprouts, wheat seedlings and so on.
