Does the sudden cold weather affect wheat?

Sudden low temperature weather has an impact on wheat, especially in different growth stages, and the degree of impact is different. First of all, the growth of wheat needs certain temperature and humidity conditions. Too low or too high temperature will affect the growth and development of wheat. Generally speaking, the optimum temperature range for wheat growth is 15℃-25℃. When the temperature is lower than 10℃, the growth rate of wheat will obviously slow down or even stagnate, thus affecting the formation of wheat ears and the development of grains. If extreme weather such as cold wave causes the temperature to drop below 0℃, or even negative temperature, then the wheat leaves will turn yellow, die and stagnate. Secondly, wheat has different adaptability to temperature at different growth stages. In the early growth stage (from germination to three-leaf stage), the adaptation range of wheat to temperature is narrow. Too low temperature will lead to poor germination and slow growth of seedlings, which will affect the yield and quality in the later stage. In the middle and late growth period (from jointing stage to filling stage), the adaptability of wheat to low temperature is enhanced, but a certain temperature and sunshine hours are still needed to ensure the development and quality of grain. To sum up, the sudden low temperature weather has a certain impact on the growth and yield of wheat, especially in the early growth stage and extreme weather such as cold wave. Therefore, farmers need to take timely measures such as covering protection and spraying protective agents according to weather changes to ensure the normal growth and yield of wheat.
