In 2012, china on the tip of the tongue broadcast a story about zhang qi-chun growing food on his roof and making dumplings with his neighbours from the roofs, prompting a rush to plant food on the roofs around the country。
Six years later, zhang gui chun has become a celebrity in many vegetable growers' circles and has grown over 20 vegetable varieties on his roof。
However, in the early spring of 2007, he had no experience with any kind of food, and wanted to build a roof garden on the roof of a common flat in beijing alley, which seemed to many alike。
Zhang gui chun beijing citizen:
With a determination not to fail, i continued to plant, and in the fourth year, the fruit of the garden was full of fruit, which was 40 pounds heavy, but not so big, because i was a chinese drug grower, and i managed to plant the garden with chinese medicine。
Zhang gui chun has also studied patented chinese fertilizers, watering at noon, and three-tier monocultures that make full use of space。
Zhang gui chun said that it would take more than a month for a quail-sized watermelon to grow to 10 pounds, and that it would cost only $2. 00 to buy a melon and common fertilizer。
So how much does it cost to build a roof garden? Zhang quichuen wrote to the journalist about $670,000 for the construction of a roof garden, waterproofing, land transport, bamboo racks and bamboo racks, not counting the money he spent on the development of pharmaceutical fertilizer。
Moreover, the first three years of his roof garden had seen little harvest, and it had not begun until the fourth year, when technology had matured, when the cost of growing the roof had fallen。
Now, his annual input of cooking on the roof has stabilized at around $4,000, mainly for the purchase of vegetable seedlings, fertilizers and water. In the harvest season, the home is almost free of the need to buy food, and many are left for friends。
