At present, wheat in our province is in the overwintering stage. Wheat seedlings are generally strong in drought resistance and frost resistance. In particular, wheat that has been sown at a suitable time and has a large amount of growth before winter is used, its roots are generally developed, and it can absorb water from deep soil and resist drought. Strong resistance to freezing. In the field soil freezing period, as long as the wheat seedlings do not appear severe symptoms such as leaf dead, generally do not water or water drought. Irrigation of wheat fields during soil freezing will cause water and ice in the fields, causing “cutting†hazards to the wheat seedlings (when the field surface moisture accumulates, the wheat seedlings will rise upward and the wheat seedlings will be broken); smaller wheat seedlings may be Because of long-term suffocation in the ice, or uprooted (commonly known as root extraction), the roots move up and suffer severe cold damage. In recent days, the temperature is low, and there are frozen, dry soil, resulting in severe water shortage of wheat fields, you can wait until the soil thawing, "cold tail warmer" irrigation once permeate (generally required daily average temperature greater than 3 °C, soil energy " When the night freezes and disappears.
