In the next week, more than temperature and rainfall weather, local farmland has a high level of corn disease and meteorological level of corn disease. Monitoring and monitoring and

1. Most of the city's summer corn grow well

At present, summer corn in most areas in the city is about to enter the pumping period. According to the latest satellite remote sensing monitoring, compared with the same period of the city's summer corn compared with the same period last year (Figure 1), the proportion of preferences and flats is 57.5%and 34.2%, respectively. Compared with the same period of the past five years (Figure 2), the proportion of preferences and flat ratios 69.4%and 22.8%, respectively.

2. There is a risk of waterlogging in local farmland in the southern region of our city

Since July, the average rainfall in the city has been 202.4 millimeters, and the amount of rainfall in various places is uneven. Most of the rainfalls of Han Ting, Qingzhou, Lintong, and Anqiu are more than 200 mm. According to the city's automatic soil moisture observation station data analysis on August 5th at 14:00 on August 5th , Fangzi, Linzhang, Zhucheng, southern Qingzhou, southern Gao Mi, and eastern Anqi in some areas of 20 cm of soils have a relative humidity of more than 90%of the soil (Figure 3), and the soil soil is too damp.

It is expected that there are many high temperatures and rainfall weather in our city in the next week. The soil of low -lying plots with too much precipitation is too wet, and farmland with poor local drainage has a risk of waterlogging. From August 6th to 7th, 11th to 12th, the highest temperature in most areas in the city is above 35 ° C, and 37-39 ° C in some areas from 11 to 12, which has a certain adverse effect on the growth of autumn crops.

3. Continue to strengthen the monitoring and prevention of corn disease

预计未来一周，我市大部地区夏玉米将陆续进入抽雄吐丝期，玉米病害进入高发阶段，8月4日，全市大部地区平均空气相对湿度在70%以上（图4），易引病害Explosion and development. It is recommended that local conditions adapt to local conditions, combined with weather forecasting and farmland climate characteristics to strengthen the monitoring and prevention of summer corn disease.

It is recommended that farmers build field drainage channels to prevent waterlogging. The plot where waterlogging is drained in time and draining water, scattered stains, cultivating the soil, and breaking the knot.
