Measures to prevent wheat frost in early spring

Paddling hoe: when the soil is back to pulp, it can loosen the soil, preserve soil moisture, increase temperature, weed, and enhance the ability of wheat seedlings to keep out the cold. No matter weak seedlings, strong seedlings or strong seedlings, we should pay close attention to hoeing during the period of turning green, and for wheat fields with a trend of prosperity and growth, we can also dig deep enough to restrain tillering in spring. When ploughing, we should pay attention to mastering shallow hoe and fine hoe, and push the bumpy hoe away while hoing; if we suppress the soil before ploughing, the soil will not be empty, thus achieving the effect of loosening and lowering fruit, increasing soil moisture and preserving soil moisture.

Suppression: the suppression of wheat fields in early spring can crush bumps, close cracks, close wheat roots and soil, and prevent cold air from invading and harming wheat seedlings. At the same time, suppression also has the effect of increasing soil moisture, which can increase the water content of soil surface and alleviate the chilling injury of low temperature.

Fertilization: fertilization in early spring can make up for the soil fertility consumption in winter, increase nutrient accumulation, promote the green growth of wheat seedlings, resist or reduce the freezing injury in early spring, especially in the years of high temperature in winter, continuous growth of wheat seedlings and high soil fertility consumption. Fertilization in early spring is particularly important. When fertilizing wheat in early spring, we should seize the favorable opportunity that the soil has just thawed and return to pulp, and use soil moisture to open ditches and apply it deeply; generally, it should not be watered so as not to reduce the ground temperature and affect the growth of wheat seedlings.

Spraying: spraying 200ppm paclobutrazol solution 30kg per mu can inhibit the growth of wheat seedlings and enhance the ability of cold resistance.
