China Academy of Agricultural Sciences called it a major breakthrough, which was the result of 30-year electric power cultivation experiment on vegetables in power grid under soil and planting conditions.
China Academy of Agricultural Sciences began to experiment with electric cultivation in 1990s. Researchers at the Academy of Agricultural Sciences set up a bare copper power grid 3 meters above the ground and introduced a fast pulse current of 50,000 volts. 50,000 volts is 200 times the voltage of an ordinary home.
According to the South China Morning Post, Professor Liu Binjiang, one of the main leaders of the project, said that the current in the power grid is only one millionth of that in An 'an, which is "harmless to plants and people nearby". 3,600 hectares of greenhouses from the Gobi Desert to the east coast participated in the electric power cultivation project supported by the government of China.
They found that the crop yield after electric tillage increased by 20-30%, which was obtained by reducing the use of pesticides by 70- 100% and reducing the use of fertilizers by 20%.
Is it really so magical to grow vegetables on the power grid?
The wave of vegetable planting in power grid triggered by the aurora in the Arctic.
About electric cultivation, Andrew Goldworthy, a botanist from Imperial College London, London, England? He said: "The academic circles are so controversial that neither supporters nor opponents can convince anyone. Before World War II, the topic of electric training gradually disappeared. "
But in fact, the United States Patent and Trademark Office also has a special classification of electric tillage. You can see that the entry of electric tillage is under the category of plant breeding in 1.3.
