Stable and good harvest of wheat

Recently, heavy rainfall occurred in the main wheat producing areas such as Jianghuai, Huanghuaihai and so on, and the epidemic risk of wheat scab increased. A few days ago, the Ministry of Agriculture and Rural Affairs issued an urgent notice, asking all localities to continue to do a good job in scab prevention and control on the basis of initial achievements in the previous prevention and control, and make every effort to ensure a stable and bumper harvest of wheat.

China is ripe, and the world is full. On the same day in long summer, in the wheat field of hua county, Henan Province, plant protection drones blew, and the wheat waves fluctuated in an orderly manner. More than 1 drones carried out unified prevention and control operations in contiguous wheat fields. "In less than 2 minutes, the spraying operation of more than 2 mu of wheat was successfully completed." Shi Wanhao, a big grain grower, is full of confidence in this year's output.

At present, wheat has entered the heading and flowering period, and it is also a period of high incidence of wheat diseases and insect pests. Wheat scab, also known as ear rot, is caused by various Fusarium infections, especially in rainy and humid temperate zones.

"Scab invades from pollen tube after flowering, and the humidity is high after rain, which is very beneficial to scab. Now take advantage of the fine weather to spray the medicine to protect the wheat ears from infection. " Chen Yipin, deputy director of hua county Agricultural Technology Extension Center and stationmaster of plant protection station, said that using plant protection drones for flying defense operation not only makes the medicine more accurate and uniform, but also achieves multiple effects with one spray, which greatly improves the work efficiency.

Statistics show that the current 1.812 million mu of wheat in hua county is growing well. "While doing a good job in agricultural technology guidance and unified prevention and control, we should also take effective measures such as grasping early and grasping small, and adopting scientific pesticide application to ensure high yield and harvest of summer grain." The relevant person in charge of hua county Agriculture and Rural Affairs Bureau said.

In order to keep a good grasp of scab prevention and control, and ensure a stable and bumper wheat harvest. Recently, the Ministry of Agriculture and Rural Affairs issued a notice demanding that the current prevention and control of wheat scab be unremittingly grasped. Necessary remedial measures shall be taken in areas with frequent and recurrent occurrences such as Jianghuai and southern Huanghuai. In the occasional areas such as the northern part of Huanghuai and North China, we should pay close attention to the weather changes. In case of continuous rainy weather, we should seize the "window period" of heading and flowering in combination with "one spray and three defenses" and implement the prevention and control measures of "spraying drugs at the sight of flowers" to prevent the occurrence and prevalence of diseases.

"At the same time, it is necessary to organize ditch cleaning and soil moisture management in time, so as to stop the rain and dry the field, reduce the humidity of the field, and avoid the high humidity and sultry microclimate in the field from aggravating the epidemic of diseases." The relevant person in charge of the Ministry of Agriculture and Rural Affairs stressed that wheat should be harvested, dried and dried in time at the mature stage to avoid the excessive humidity of wheat grains, which will lead to the re-infection and reproduction of Gibberella and affect the quality of wheat.

The data show that 353 million mu of wheat scab has been implemented in various places, and the prevention and control has achieved initial results. "At present, the area of diseased ears is 2.95 million mu, a year-on-year decrease of 44%, and it only appears in some fields along the Yangtze River, southern Henan and southern Shaanxi."
