Management measures in winter wheat field in Hebei

According to the pre-winter survey, most of the wheat fields are in good condition, and the first and second types of seedlings account for 88%. Due to the excessive accumulated temperature and the large amount of seeding, the growth trend of some wheat fields is obvious. The wintering base of sheath blight, root rot, and wheat stubble is equivalent to that of normal years. Broad-leaved weeds have a large area, and grass weeds have an increasing trend.

The technical advice for spring management is to strengthen the suppression and strokes in early spring. Repression and planning should be carried out in combination with different wheat fields. Dryland wheat fields, wheat fields with a lot of filth, and wheat fields with loose surface caused by freezing and thawing should be repressed at noon in the early spring and warm weather. After the increase of the surface enthalpy, finely plan, cut off the soil capillary, protect the mites, warm up, and eliminate the weeds. The wheat fields that have been repressed after sowing or before winter and the wheat fields with good sensation are only suppressed. In the wheat field with a prosperous trend, it is necessary to suppress it in the afternoon of fine weather, and suppress it. The second is to delay the first irrigation time in spring. In view of the fact that most of the wheat fields are better, in the early spring, the first fertilizer can be postponed until the end of the period from the end of the body to the jointing stage, and 15 kg of urea per acre is applied with the watering. Individuals have a trend of de-fertilization before the winter, and the greening is delayed, but the wheat fields with sufficient sensation can be applied with a small amount of nitrogen fertilizer during the early spring. The third is to take appropriate control measures. For the wheat field with a total stem number of more than 1 million during the regreening period, and the plant height is high, there is a risk of lodging, and it is necessary to control and prevent the fall before the jointing period, and to inhibit the spring ineffective tillering and control. The fourth is to timely control pests and diseases. It is necessary to pay close attention to the occurrence of pests and diseases in wheat fields, timely report and actively take comprehensive prevention measures.
