Recently, large-scale high-temperature weather has occurred in North China and Jiangnan. Since July 18, high-temperature weather above 35 °C has appeared in the western, northern, southern, and eastern parts of the northwestern region. The high temperature days in most of the above areas are 3 to 7 days, and in western Inner Mongolia, central Jiangxi, and eastern Xinjiang. 8 to 10 days, of which the highest temperature in the Inner Mongolian Lake is 8 days and the maximum temperature is over 40 °C. On the 20th, the highest temperature in the lake is 42.7 °C. The highest temperature in the Ejina Banner of Inner Mongolia reached the highest historical value of 42.9 °C since the meteorological record. Since July 21, Hebei, Beijing, Tianjin and other places have entered the stage of high temperature and high humidity, and the daily maximum temperature is close to or exceeds 35 °C, which is different from the dry heat type hot weather from July 2nd to 8th. Sweltering hot weather.
The meteorological department expects that there will still be hot weather in most of the northern part and the south of the Yangtze River. It is estimated that during the day, Beijing, Tianjin, Hebei, Shanxi, south-central and northeastern Shaanxi, central and northern Ningxia, most of Henan, central and western Shandong, northwestern Hubei, northeastern Sichuan, Chongqing, northeastern Guizhou, most of Hunan, There are 35°C in the central and northern Jiangxi, most of Zhejiang, and the northwestern part of Hainan, and the local high temperature of 37~38°C; the central and western Inner Mongolia, the central and western Gansu, the Xinjiang Turpan Basin and the eastern part of the southern Xinjiang Basin will have 35-37 °C, high temperature weather above 40 °C. The Central Meteorological Observatory continued to issue a high-temperature yellow warning at 6:00 this morning. In addition, heat stroke is prone to occur in parts of western Gansu, central and western Inner Mongolia.
According to reports, the current arid area of ​​Inner Mongolia is 591,000 square kilometers, of which the area has a heavy drought area of ​​111,000 square kilometers. The heavy drought areas are mainly distributed in Bahrain Zuoqi, Chifeng City, the northern part of Xilin Gol League in the Inner Mongolia Autonomous Region, the central and northern parts of Ulan Qab, the northwest of Ordos City, the northern part of Bayannaoer City, Wuhai City and Alashan League.
Concerns and Suggestions
First, the northern region and the south of the Yangtze River and South China need to strengthen field management. All parts of the north should strengthen water and fertilizer management of dryland crops such as corn, cotton and soybeans, timely cultivating and weeding, controlling pests and diseases, and promoting the stable growth and development of crops; Jiangnan and southern China should grasp the early rice harvest and complete the task of transplanting late rice in a timely manner. He Miao should strengthen field management, timely topdressing, and pay attention to water temperature adjustment in case of high temperature weather.
The second is to strengthen the prevention of adverse effects of high temperature weather on human health. Continued high temperature weather can easily lead to heat stroke in the elderly, children and infirm, and it is easy to cause diseases such as cardiovascular disease, and even death. It is necessary to strengthen the prevention of high temperature weather damage to the human body.
The third is to strengthen the scientific dispatch of energy and water resources. Relevant localities and departments need to strengthen the deployment of cross-regional power, water resources, heatstroke prevention and cooling facilities, medical equipment, and timely launch emergency response plans for extreme high temperature heat waves. It is necessary to strictly limit the start-up production of high-energy-consumption and high-water-consuming enterprises, and give priority to ensuring the use of electricity for urban and rural residents.
The fourth is to strengthen the prevention of drought and fire caused by high temperature heat waves. At present, China is in the high temperature and drought season. High temperature is the main cause of large-scale drought. In 2006, high temperature caused severe drought in Chongqing and Sichuan. In late June this year, high temperature and lightning also caused many forest fires in the Daxinganling area. Therefore, it is necessary to strengthen prevention against drought and fire during the high temperature and drought season.
It is expected that cotton mites in the Yellow River Basin will be heavily biased this year, and it is necessary to timely control
Usually from early July to late August, cotton enters the longest stage of growth and development - the flowering and boll period. At this time, natural resources such as light, heat, water and gas are abundant; on the other hand, natural disasters such as wind, hail, drought, and waterlogging frequently occur during this period, and pests and diseases are seriously endangered. The farmer said that "cotton is volute, good and bad, bad can get better", this is the truth.
This year, many cotton in the main cotton producing areas have been affected by low temperatures and excessive rains from sowing to buds. The progress of fertility has been delayed by 7-10 days compared with normal years, and the seedlings are generally not as good as before. According to the analysis of the current occurrence of cotton pests and diseases, meteorological conditions and other factors, the overall pests and diseases of cotton in the middle and late this year will be moderate, and the occurrence of insect pests may be mostly lighter than last year, but the occurrence of diseases will be more important than last year.
In recent years, insect-resistant cotton has been widely promoted, which has reduced the number of times of cotton field use, but has accelerated the breeding of cotton blind mites. In addition, cotton blind cockroaches are like wet pests, rainy years and irrigated cotton areas, the number of cotton blind cockroaches is generally more serious.
It is expected that in the middle and late stages of this year, cotton mites in the Yellow River Basin will occur more heavily, and the cotton areas in the Yangtze River Basin will occur moderately. In addition, the three generations of cotton blind cockroaches will occur from late July to mid-August. It is recommended that if cotton fields have been invaded by cotton blinds, the spraying time is preferably in the evening, because dew in the morning will generally reduce or lose the concentration of the liquid; at noon, there will be shortcomings such as rapid evaporation of the liquid and affecting flowering and pollination.
