Winter wheat management

Since the beginning of autumn this year, most of the main wheat producing areas have had less precipitation and higher temperatures, which has led to the continuous expansion of the area affected by wheat, and the trend of some wheat fields has become prosperous. At present, it is the peak period of long-leaved, rooting, tillering and population development of winter wheat, but the continuous development of drought conditions has resulted in the loss of seedlings and ridges in some wheat fields, and the growth and development of wheat has been hindered. At the same time, high temperatures have caused Shandong, Hebei, Henan and Gansu provinces. Some wheat fields appear prosperous. In order to mitigate the adverse climate effects such as drought, ensure that the formation of strong seedlings before winter and enhance the cold-resistance capacity proposes the following three measures:
One is to pour good winter water to achieve safe wintering. If you have not cultivated before planting, and you have poor lye, you should pay attention to watering now to cultivate strong seeds before winter. For the average wheat field, winter water should be poured when the daily average temperature falls to about 5°C, and it ends when the night's average temperature drops to zero. Huanghuaihai region should start in late November and end in early December. After pouring, pay attention to timely scratching and remove soil compaction. A prosperous wheatfield with good sensation may not be poured over winter water.
The second is to take repression and other measures to control and prosper. Prosperous wheat fields should be repressed to improve their antifreeze capacity. For dryland wheat fields with poor site preparation quality, excessive land surface dust, and low moisture levels, they can be repressed before winter and pressed shallowly afterwards in order to raise their reserves. The method is mainly used for repression by means of roller compaction or artificial stamping by a stone mortar or iron.
The third is to strengthen the control of pests and diseases. At present, it is a critical period for the comprehensive prevention and control of wheat diseases and weeds. A chemical weed control can basically control wheat field weeding and has a multiplier effect. For wheat rust, cockroaches, cockroaches, beetles, earthworms, wheat aphids, sloughs and other pests and diseases to make predictions and comprehensive prevention.
