Chinese growers have the answer to a question that has been baffling scientists for three centuries: Can electricity boost plant growth?
To find out, China has been conducting the world’s largest experiment and the results are transforming agricultural production in the world’s most populous nation with a jolt.
Across the country, from Xinjiang’s remote Gobi Desert to the developed coastal areas facing the Pacific Ocean, vegetable greenhouse farms with a combined area of more than 3,600 hectares (8,895 acres) have been taking part in an “electro culture” programme funded by the Chinese government.
Last month the Chinese Academy of Agricultural Sciences and other government research institutes released the findings of nearly three decades of study in areas with different climate, soil conditions and plantation habits. They are hailing the results as a breakthrough.
The technique has boosted vegetable output by 20 to 30 per cent. Pesticide use has decreased 70 to 100 per cent. And fertiliser consumption has dropped more than 20 per cent.
