This is how to grow pollution-free vegetables so they truly live up to the name

When it comes to growing vegetables, one thinks of Shouguang in Shandong, the hometown of vegetables. I occasionally had the good fortune to visit Shouguang and see with my own eyes the high-tech vegetable growing there. In the past I had only seen it on TV or online, and only when I saw it with my own eyes did I truly feel the charm of agricultural technology. According to the local technicians, this efficient three-dimensional cultivation technique is pollution-free, all soilless culture and hydroponics, and can be called organic vegetables. It is what city people love most, though of course the price is not something ordinary folks like us can afford. I sincerely hope that vegetables grown with this cultivation technique can soon reach the dining tables of ordinary people.
