Necessary conditions for plant growth
One: light. The growth of all things depends on the sun, so the intensity of light has a great influence on the growth of plants, some plants like positive, some plants like negative.
Two: moisture. Almost all living things in the world are inseparable from water. Without water, they cannot grow and reproduce, and can only go to death.
Three: temperature. The temperature directly affects the growth and dormancy of plants. Too high or too low temperature can affect the death of some plants.
Four: nutrients. Sufficient nutrients can make plants grow vigorously, while dwarf plants are weak.
Five: soil. The choice of acidity or alkalinity is very critical for plants, and the quality of soil texture is the main basis for plant growth.
Six: Air. Air is the main place for plant gas exchange, carrying out the process of oxygen and carbon dioxide exchange.
