1, ensure winter water winter fertilizer To ensure that winter water and winter fertilizer can improve the soil nutrients, water conditions, and stabilize the change in the ground temperature, for the green seedlings to turn green and improve the tillering (when the wheat is developed, the branching at the base of the seedling - the seedling near the soil is called tillering) The conditions to grasp the initiative of the spring management. Saline-alkali winter irrigation also has the effect of pressure alkali change soil. The amount of winter fertilizer should not be too large, should be due to the seedling system, the amount of mid-production wheat fields accounted for about 20% of the amount of topdressing, without the application of phosphate fertilizer land, should be combined with nitrogen and phosphorus. Fertilizers have been applied to the wheat field, do not follow winter fertilizer. The pouring of winter water ends when the average daily temperature of 7 to 8°C is frozen overnight. Late buckwheat, short growing period before winter, leaves less, less root, or "a leaf", in order to use the effective accumulated temperature in the early winter and early spring freezing and thawing period, to increase the sowing ground temperature, promote root growth and increase soil moisture in the case of large Next, do not pour winter water. 2. Sham, repression, loose soil In the water-fed wheat field above medium fertility, after the winter, when the total number of pods per acre reaches 1.5 times the planned number of panicles, the sorghum roots should be cut off, and the rakes with the two left and right teeth removed should be interlaced to a depth of 10 cm. After the squats, they should immediately take advantage of the facts to prevent pressure seedlings and wind loss, and to pour winter water in time. For wheat fields with large groups, squat cutting has obvious effect on the control of group development. For wheat fields that are overgrown by over-promoting groups, suppression measures can be taken to suppress tiller growth before winter. In fields where the cultivation is extensive and the crops are laden with more litter, they are repressed before they are frozen on the ground, crushed and shredded to make up for cracks, and they can protect the soil from heat and moisture. Pressure wheat should be carried out after noon so as to avoid frost cracking the wounded seedlings in the morning, and saline soil should not be suppressed. It should be noted that, after the winter wheat field is poured, it is easy to cause surface compaction, cracks, soil moisture, pull off the wheat roots, and freeze the dead wheat seedlings. 3. Note the defense against freezing damage and post-freezing field management: To prevent freezing damage, in addition to the use of improved varieties, sufficient base fertilizer, and strong seedlings, it is also necessary to apply farmyard manure and covert seedlings during the wintering period to suppress heat, fertilize soil and prevent freezing. Where conditions permit, it can also divert winter irrigation. If the wheat leaves are frozen, as soon as the tillering festival is not frozen, the quick-acting fertilizer should be applied as soon as possible to promote seedling transformation; in case of dry freezing, the top dressing should be combined with watering and drought resistance.

Early winter and winter wheat management
As the saying goes: "In the winter, the third floor of McGee was slept with a baboon." We are all hoping that God can take care of the farmers' friends. In the winter, we can bring down a few snows and keep the wheat warm and moist. However, there is another word called "contributing to people." We cannot wait for God's coveting, and the correct management of man is more important. So how do we manage wheat management in the early winter and winter months?
