At present, it is the winter wheat seedling stage, which is the key period to promote the seedlings and seedlings. According to the author's field investigation, some wheat fields have drought, lack of seedlings, cracks, etc. If the countermeasures are not taken in time, it is difficult to form a strong seedling before winter, which will affect the bumper harvest of wheat next year.

1. Drought. It mainly occurs in the ploughing and ploughing of wheat fields, especially in the wheat field where straw is returned to the field. Although some wheat fields can be used before sowing, the bottom stalks are insufficient. At present, most of the ploughed wheat fields are dry and water-deficient, and some plots are Incomplete seedlings.

Countermeasure: Grasp the watering, and carry out the winter water in combination with the winter water before the winter.

2. Lack of seedlings. Due to the drought or the poor quality of sowing, some wheat fields lacked seedlings and ridges. After the emergence of wheat, no seedlings were found in the line of 10 cm or more in the wheat line, and no seedlings were broken in the 16 cm or more. Some farmers do not pay attention to the shortage of seedlings and ridges. They always think that through wheat tillers, a small number of seedlings and ridges can be compensated for, and it is difficult to make up for it.

Countermeasure: replant early, select the same variety as the local block, first soak in warm water at 20 °C for 3 to 5 hours, keep moist after fishing, and carry out germination. When the seed starts to sprout, use a small hoe or opener to ditch. Replanting, when the sputum is poor, a small amount of water is poured into the ditch, and the soil is planted after the planting; for the plots that are too late to replant and replant after seeding, the seedlings or seedlings can be transplanted in the wheat tillering stage. You can also choose the same variety of strong seedlings in the adjacent plots for transplanting and replenishing.

3. Cracks. In some wheat fields where montmorillon water is poured, cracks of different degrees appear on the ground, soil water evaporation accelerates, wheat is not easy to form strong seedlings before winter, cold air enters deep soil in winter, wheat is prone to freezing damage, and serious wheat seedlings are easy to freeze.

Countermeasures: Grasp the strokes, make up the cracks, reduce the evaporation of soil moisture, maintain the soil moisture, eliminate weeds, improve the soil permeability, promote microbial activities, and promote the early development of tillers and roots.
