1. Seedling replanting seedlings, seedling transplanting wheat seedlings after seedling emergence, seedlings should be timely reseeding. For wheat fields lacking seedlings and ridges, it is necessary to replant in time. Also in the 3 to 4 leaf stage, the defoliation and defoliation of defoliation and defoliation in wheat fields are conducted. Wheat seedlings must be transplanted with soil and watered after planting. For wheat fields that are difficult to emerge due to soil moisture, they should be watered quickly.
2. Timely cultivating, prompting seedlings and early-producing various types of wheat fields to be cultivated before winter. Benefits of cultivating: On the one hand, soil compaction can be removed and roots can be increased; on the other hand, weeds can be removed. About 15 days before the winter wheat is overgrown, if the growth of the wheat seedlings is too high due to excessive fertilizer and water, or high temperatures in autumn and winter, deep plowing should be conducted 10 to 15 cm in advance of winter to control the growth and prevent freezing damage.
3, chemical weeding chemical weeding is better in the late mid-November, when the wheat field weeds are mostly in the 3-leaf stage, seedlings are easily removed. Generally, 50-60 ml of mussels per mu, plus 1 gram of DuPont superstars, are sprayed on 40 kg of water evenly to control weeds in wheat fields. Care should be taken not to re-spray and spray them so as not to cause injury.
4, timely winter irrigation on the poor soil moisture, wheat farmland, should be winter irrigation. The principle of winter irrigation is to freeze at night, and winter irrigation is just right, that is, when the temperature drops to 3Â°C in the middle of December, winter irrigation can promote root growth. For defertilized wheat fields can be combined with winter irrigation per acre as appropriate to apply urea 5 ~ 8 kg.
