Is carbon-rich agriculture a patented technology?

Carbon-rich agriculture is a patented technology to increase output, improve quality and shorten maturity. Because of the invention patent of "an application method of industrial CO2 in crop growth", the method of obtaining cheap industrial CO2 is fully disclosed. Measures to increase crop yield, improve quality and shorten maturity when the concentration of carbon dioxide in the air is higher than 3 times;

Implement measures to increase production and improve quality of carbon-rich rice;

Implement measures to increase production and improve quality of carbon-rich crops in greenhouse;

Measures to increase yield and quality by planting carbon-rich crops (soybean, wheat and corn) in dry land.

To sum up, I really can't think of any part of the emerging carbon-rich agriculture that is not within the scope of the invention patent! Even if there are other technologies that are not within the scope, some people have technology! If you apply for a patent and later get authorization from the patent office, that is patented technology!

So carbon-rich agriculture is a patented technology! Patent license is needed to implement patented technology! !
