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 the prevention and control of scab 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.

The Central Plains is ripe, and the world is full. On the same day of long summer, in the wheat field of hua county, Henan Province, the plant protection drones roared and the wheat waves fluctuated orderly. 10 More than 0 drones carried out unified prevention and control operations in contiguous wheat fields. "In less than 20 minutes, the spraying operation of more than 200 mu of wheat was successfully completed." Stone, a big grain grower, is full of confidence in this year's output.

At present, wheat has entered the heading and flowering stage, which is also the high incidence period 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 regions.

"The scab invades from the pollen tube after flowering, and the humidity is high after the rain, which is very beneficial to the scab. Now spray some medicine while the weather is good to protect the ears of wheat from infection. " Chen Yipin, deputy director of hua county Agricultural Technology Extension Center and stationmaster of plant protection station, said that the use of plant protection drones for flying defense operations not only made the application more accurate and uniform, but also realized multiple effects with one spray, which greatly improved the work efficiency.

Statistics show that the wheat in Huaxian 18 12000 mu is growing well at present. "While doing a good job in agricultural technical guidance and unified prevention and control, we should also take effective measures such as grasping early and grasping small, and scientifically applying pesticides to ensure high yield and bumper harvest of summer grain." The relevant person in charge of hua county Agriculture and Rural Affairs Bureau said.

In order to continue to do a good job in scab control and ensure a stable and bumper harvest of wheat. Recently, the Ministry of Agriculture and Rural Affairs issued a notice, demanding unremitting efforts to prevent and control the current wheat scab. Necessary remedial measures should be taken in frequent and frequent areas such as Jianghuai and southern Huanghuai. Occasional areas such as northern Huanghuai and North China should pay close attention to weather changes. In case of continuous rainy weather, we should combine the "one spraying and three prevention", seize the "window period" of heading and flowering, and implement the prevention and control measures of "spraying medicine when seeing flowers" to prevent the occurrence and epidemic of diseases.

"At the same time, it is necessary to organize ditch cleaning and soil moisture management in time, so that rain can prevent the field from drying, 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, aired 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 control has been implemented in various places, and the control has achieved phased results. "At present, the diseased ear area is 2.95 million mu, a year-on-year decrease of 44%, which only appears in some fields along the Yangtze River, southern Henan and southern Shaanxi."
