How to do winter wheat seedlings

Physiological death. Under normal conditions, wheat can withstand temperatures as low as minus 15°C during the winter, and is not affected by freezing. However, the overgrowth or too weak wheat seedlings, because of the low sugar content at the tillering festival, the resistance is weak, even if the temperature is below -15 °C, the phenomenon of dead seedlings often occurs, especially in the event of severe temperature changes, freezing killed. The seedling phenomenon is even more serious.

Dry hunger. As the topsoil melts in early spring, the lower layer still freezes, and the leaves begin to evaporate, while the roots cannot absorb nutrients and moisture, causing dryness or hunger, and in severe cases, the plants will die.

Suffocate death. In general, pouring winter water is too late or pouring green water prematurely, and when the amount of water is high, the ground will form ice shells. Because wheat seedlings lack oxygen, they will die due to suffocation.

Drought died. Mostly due to extensive site preparation, too shallow sowing, poor lyrical condition and weak root system, the wheat seedlings are not strong enough to grow. The tillering festival is in dry soil. In the case of soil freezing, the roots are not easy to absorb water, and there is still transpiration in the shoots, making the wheat seedlings. It is difficult to maintain the body's water balance and it is easy to die.

Ling lifted, Ling cut. The seedlings are weak, the soil moisture is high, the lower layer is frozen, and the volume expands. The iced soil layer lifts the soil and the root together, and the root is broken and died. Some of them did not die. The birthing section was exposed on the ground, secondary roots could not occur, and the plants wobbled. If they did not cultivate soil in time, they would die in the spring.

Prevention and control measures: fine soil preparation in autumn, increasing fertilization materials, selecting resistant varieties, planting sufficient seeds, cultivating strong seedlings, and timely winter irrigation. According to the situation of lyrics and seedlings, measures such as planing, repression, and covering soil and miscellaneous fertilizers were adopted to enhance the resistance of wheat seedlings to damage.
