1. Improve the quality of sowing and cultivate strong seedlings before winter. First, wheat should be applied with 607 kg/ha of organic fertilizer, 300-400 kg/ha of urea, 650-900 kg/ha of phosphate fertilizer before planting, and the bottom of the soil should be ploughed once. In the case of drought, the bottom of the water is poured, and the soil is finely grounded to reach the level, the soil is fine, and the soil is good. Second, before the sowing of wheat, the seeds should be selected and sieved to make the seeds full and uniform in size; the seeding and seed germination tests should be carried out to ensure that the germination rate of the seeds is greater than 95%; and the seeds are mixed with seeds and soaked. Third, the wheat should be planted in a timely, appropriate, and deep manner.

2. Strengthen the integrated management of the field and control the seedlings to promote weak seedlings. For wheat fields that have a tendency to grow, plant growth retardants can be sprayed to delay the growth of wheat seedlings. For wheat fields with late seeding, weak seedlings, single-legged seedlings, water-stained seedlings, phytotoxic seedlings, and insufficient base fertilizer, 150-225 kg/ha of NPK compound fertilizer can be applied before winter to inhibit the growth of wheat seedlings and promote Tillers and roots grow.
3. Timely winter irrigation, safe winter. Timely winter irrigation is an effective measure to prevent winter frost damage in wheat, and it can store enough water for spring growth of wheat to achieve the effect of winter water spring, spring drought and winter defense. Winter irrigation can form a good soil water environment, regulate soil nutrients in the plough layer, increase soil heat capacity, generally increase the ground temperature by 1 to 3 °C, and at the same time bridge the soil joints and promote the growth and growth of seedlings. Winter irrigation should be watered at a temperature of 4 ° C. If the temperature is lower than 4 ° C, there is a risk of freezing damage in winter irrigation.
Prevention and control measures after winter frost damage: The wheat field after freezing damage can not be easily destroyed. It is necessary to take timely remedial measures such as topdressing, watering and spraying auxin to promote wheat growth and development. The first is to strengthen the management of fertilizer and water. For the wheat leaves that are frozen and the young ears are not completely frozen, that is, the wheat leaves at the base of the wheat seedlings turn yellow and the leaves are withered, the water should be washed early to prevent the young ears from dehydration and death. The second is to cultivate and protect the ground temperature. The wheat fields damaged by freezing should be ploughed and soiled in time, and the water should be warmed to promote the growth and development of wheat and compensate for the damage caused by freezing damage.
