What are the measures to prevent frost damage in wheat in early spring? Do this to prevent frost damage

Hoeing: When the soil thaws and becomes muddy, carry out hoeing on the frozen surface, which can loosen the soil, preserve moisture, increase temperature, control weeds, and enhance the cold resistance of wheat seedlings. Regardless of weak seedlings, vigorous seedlings, or strong seedlings, hoeing should be done promptly during the greening period; for wheat fields with a tendency to excessive growth, deeper hoeing can be done appropriately to suppress spring tillering. When hoeing, pay attention to shallow and fine hoeing, and push apart clods while hoeing; if pressing is done before hoeing, the soil will not be hollow, thereby achieving the effect of loose top and firm bottom, and improving moisture retention.

Pressing: Pressing wheat fields in early spring can break up clods, close cracks, make wheat roots closely contact the soil, and prevent cold air from intruding and damaging wheat seedlings. At the same time, pressing also has the effect of raising moisture, which can increase the water content of the surface soil and help alleviate low-temperature cold damage.

Fertilization: Fertilizing wheat in early spring can compensate for the consumption of soil fertility in winter, increase nutrient accumulation, promote the greening and growth of wheat seedlings, and resist or reduce early spring frost damage, especially in years when winter temperatures are high, wheat seedlings continue to grow, and soil fertility consumption is large, early spring fertilization is particularly important. For early spring fertilization of wheat, seize the favorable opportunity when the soil has just thawed and become muddy, and apply fertilizer deeply in furrows by using soil moisture; generally, watering should not be done, so as not to lower soil temperature and affect wheat seedling growth.

Spraying: From the greening stage to the jointing stage of wheat, spray 30-40 kg of 200ppm paclobutrazol solution per mu, which can inhibit wheat seedling growth and enhance cold resistance.
