Corn is warm and the optimum temperature for seed germination is 25-30°C. The jointing period requires a daily average temperature of 18°C ​​or more, and the higher the temperature, the faster the growth. From tasselling to flowering, the daily average temperature is 26-27 °C. Grain filling and maturation are required to be maintained at 20-24°C to facilitate the accumulation of nutrients. When the temperature is lower than 16°C and higher than 25°C, the amylase activity is affected, resulting in poor grain filling. Maize varieties can be divided into three types: early-maturing, medium-maturing and late-maturing, and their accumulated temperature requirements are 2000-2300°C, 2300-2500°C and 2500-2800°C, respectively.
Maize is a short-day crop. Under the sunshine conditions within 12 hours, the plant growth is short, tasseling and maturity are earlier. If given long-day conditions, the plants grow tall, the stems and leaves are lush, but the development is slow, the flowering is delayed, and even the ear cannot be formed. Generally, early maturing varieties respond slowly to the length of light, and late-maturing varieties are more sensitive. Photosynthesis is a four-carbon pathway and is a four-carbon crop. It can effectively use strong light and can also perform photosynthesis under low light and low CO2 concentration.
Corn can grow on sandy soil, loam, and clay. Suitable soil pH is 5-8, with 6.5-7.0 optimum. The ability to resist salt and alkali is poor, especially chloride ions are more harmful to corn.
