Under the influence of factors such as drought-resistant watering and artificial rainfall, the drought situation in the Huaibei region has greatly eased. As temperature rises and rainfall increases, wheat is vulnerable to waterlogging, grass damage and disease, and measures should be taken to prevent it as soon as possible.

Waterlogging Recently, the rainfall in Huainan area has increased significantly, and local lands have caused waterlogging. As early as possible, do a good job of dredging and dredging the field trenches, so that the "three ditch" matching, trenches and the same. Exclude the water in the field in time to prevent water damage caused by continuous rain in the spring.

Grass damage is affected by drought, and the effect of autumn is poor, and the problem of grass damage in spring is outstanding. The temperature rose recently, and after the rain, the locusts were suitable. The weeds in the field began to sprout. Before the jointing of wheat, we should seize the favorable weather of “cold tail warmer”, select the appropriate pharmaceutical agent to eliminate it, and ensure that the low-temperature frost weather below 0°C is not encountered within 7 days after the drug is used to avoid phytotoxicity.

The disease jointing stage is the peak period of wheat sheath blight, and the prevention and control of the disease in the early stage of jointing will cause the disease to spread. In the early stage of jointing of wheat, the fields with a diseased plant rate of 20% were promptly treated with Jinggangmycin, hexylenol, tebuconazole and other drugs, and a large amount of crude spray was used to improve the control effect.

In addition, the cold and cold damage can not be ignored. Although this year's wheat has a long and small area, the growth period has also been postponed, and the probability of freezing damage has been small. However, it cannot be completely ruled out that there will be no freezing and freezing damage. When the wheat meets the cold and the cold, it is generally investigated 2-3 days after the low temperature, and the timely application of the recovery fertilizer to strive to shake the tiller and high-section tillering into the panicle, to restore the yield loss.
