There is no second flourishing of wheat. If it thrives before winter and grows for a long time, it will not thrive. That is to say, if all the nutrients are consumed before winter, the nutrients will be consumed in advance when the next spring starts to elongate and grow ears. If the nutrients cannot keep up, the yield will definitely not be high. So what are the hazards of wheat growth?
The Harm of Wheat Prosperity
1. Winter and early spring are prone to freezing damage
The stems and leaves of flourishing wheat seedlings are tender, with insufficient storage sugar, decreased cell fluid concentration, and significantly weakened frost resistance. They are highly susceptible to winter freezing damage and late spring cold damage, with mild cases of withered leaves and dead tillers, and severe cases of frozen young ears.
2. Vulnerable to diseases
If the temperature in autumn and winter is high, the overwintering base of the pathogen will increase, and the disease resistance of the thriving wheat seedlings will decrease. Under suitable conditions (rainy spring and insufficient light), it is very easy to cause diseases such as sheath blight, powdery mildew, and root rot.
3. Prone to lodging in the middle and later stages
The basal internodes of flourishing wheat seedlings are long, the stem walls are thin, and dry matter accumulation is less. More nutrients are supplied to the aboveground parts, resulting in poor root development, fewer secondary roots, and shallow root roots. If there is a storm in the middle and later stages, it is easy to collapse and cause heavy losses.
