A Detailed Guide to the Latest Prevention Methods for Late Spring Cold Damage in Wheat
In spring, temperatures rise relatively quickly, but in the later part of spring, prolonged rainy weather or cold air outbreaks can easily cause late spring cold, which has a huge impact on wheat growth and development at this time and seriously harms wheat yield and quality. So what should be done about late spring cold in wheat? Let's take a look together with the editor at the prevention methods for late spring cold in wheat.
1. Sow appropriately late
Late spring cold in wheat is relatively common. For this kind of weather, in order to reduce freeze damage to wheat, first of all, sowing can be done appropriately later, without sowing too early, and you should not follow the crowd and start sowing just because others have already sown. The best sowing time can be in mid to late October. Sowing during this period will cause wheat to show excessive growth before the soil freezes.
2. Control excessive growth
Next is controlling excessive growth. This step is generally carried out before the New Year. Many growers prefer to control excessive growth after the New Year and neglect controlling it before the New Year, but in fact, controlling excessive growth before the New Year is still quite effective. This is because at this time, after the pesticide has just been applied, the wheat has a more stable base, extremely thick stems, and a relatively developed root system. When late spring cold occurs in spring, its cold and drought resistance are relatively strong, and its resistance to late spring cold is strong. Also, when encountering other harsh climates, it will not lodge.
3. Irrigate with freezing water
Next is to irrigate once with freezing water before the soil freezes. Many people think that freezing water is not important, but in fact, irrigating with freezing water can not only increase soil temperature and avoid root frost injury, but also give wheat a relatively strong cold resistance throughout the winter, and the root system is also relatively developed. When encountering late spring cold weather, its resistance will be a bit stronger, and large-scale death will not occur.
