At noon on a hot summer day, after a hot shower, experienced vegetable farmers will immediately use the well water to pour the vegetable garden again. This is what is often said in the production of "watering garden". Why is this?
Before and after noon in summer, the ground temperature is relatively high, up to 40°C, and even higher, so the respiration of the crop roots is very strong. After the shower, the soil was full of moisture and water vapor, the air condition deteriorated rapidly, the respiration of the roots could not be carried out normally, the growth of vegetables was inhibited, and in severe cases it also caused a large number of vegetable deaths. If a string of water with low temperature is used in a timely manner, the ground temperature can be lowered, the water vapor can be driven off, and the air condition of the soil can be improved, thereby reducing the hazard of thermal showers and preventing the death of vegetables.
