Thunderstorm crops mean that the soil can increase after a thunderstorm.
Under the action of thunder and lightning, nitrogen reacts with hydrogen to generate ammonia, and ammonia, carbon dioxide and rainwater can interact to generate ammonium bicarbonate, which falls into the soil with the rain. Ammonium bicarbonate can provide N element for crop production, which belongs to nitrogen fertilizer.
In thunderstorm weather, due to discharge conditions, oxygen and nitrogen in the air combine to form nitrogen oxides, which undergo complex chemical changes and eventually form nitrates that are easily absorbed by crops.
Therefore, the required N element is provided for crops, which belongs to nitrogen fertilizer: N2+O2 = 2NO (discharged), 2NO+O2 = 2NO2, 3NO2+H2O = 2hno3+NO.Nitric acid falls to the ground with the rain and penetrates into the soil to generate nitrate.
The role of nitrogen fertilizer:
Nitrogen fertilizer refers to the unit fertilizer with nitrogen (N) as the main component, which can provide nitrogen nutrition for plants after being applied to soil. Nitrogen fertilizer is the largest fertilizer variety in the world. Appropriate amount of nitrogen fertilizer plays an important role in increasing crop yield and improving agricultural product quality.
Nitrogen fertilizer can be divided into ammonia nitrogen fertilizer, ammonium nitrogen fertilizer, nitrate nitrogen fertilizer, ammonium nitrate nitrogen fertilizer, cyanamide nitrogen fertilizer and amide nitrogen fertilizer according to nitrogen-containing groups. The main raw material for the production of chemical nitrogen fertilizer is synthetic ammonia (Haber process plant for the production of synthetic ammonia was built in 1909, which was first industrialized in Germany and became the basis of nitrogen fertilizer industry).
In the 1940s and 1950s, ammonium sulfate was the most important nitrogen fertilizer. Ammonium nitrate was added in 1960s; Since 1970s, urea has become the main nitrogen fertilizer. Ammonium bicarbonate is one of the main nitrogen fertilizer varieties produced in China in 1980s.
