Dealing with winter wheat has three tricks

The cold-killing of dead seedlings to prevent and control wheat is a relatively self-regulating crop. Although wintering period suffers serious freezing injury, as long as the birthing festival does not die, it is still white or green, and after returning green, new tillers can be grown and become spikes. As long as spring management is strengthened, good yield can still be obtained. Therefore, in the management of wheat fields where wheat is overwintering, it is necessary to grasp the word “early” and reflect a “promotion” word.

Remove dead leaves and increase photosynthetic. Due to the severe dead leaves, the residual green leaves in the dry leaves cover of wheat fields are also covered by dry leaves, affecting the photosynthesis of wheat. When the temperature rises in spring and the topsoil is melted, the leaves of wheat ridges and ridges should be used to promote the growth of the heart. .

Topdressing nitrogen fertilizer to promote rejuvenation. Immediately after wheat is returned green, topdressing 10-15 kg of urea to promote wheat as soon as possible rejuvenation.

According to local conditions, timely watering. Flexible watering according to the ground temperature and soil moisture. Generally, when the ground temperature of wheat is 5 centimeters after returning green, the amount of water should not be too large and the water should be poured lightly. Deferring the watering time is better.

Foliar fertilization, nutritional supplements. After wheat suffers from freezing injury, it is necessary to pay attention to spray 1 to 2 times of Yi Jia boron and other nutrients to supplement the nutrients in wheat and promote the recovery of wheat as soon as possible.

The ploughs are ploughed and warmed. After the wheat field is surface-frozen, early ploughing and hoeing will be carried out to increase the temperature and protect the pods, and to promote the early and early emergence of the wheat seedlings, increase the number of tillers, and increase the percentage of spikes.

Too shallow sowing causes winter dead seedlings to prevent and control. Strictly follow the sowing technique procedure, determine the sowing depth according to soil moisture, and control the seeder's traveling speed within 4 kilometers per hour.

Infestation of disease caused by pests and diseases caused the death and control of wheat seedlings. Using the soil preparation process, the pathogens in the soil, soil pests and voles were destroyed. Make full use of seed coating agents and other measures.
