This week's major agricultural and agricultural activities in
At present, some parts of the northwestern region are harvested and sun-filled in winter wheat, early rice, spring maize, spring peanut and spring soybean harvest in parts of South China and Jiangnan; double-season late rice breeding and partial transplanting in Jiangnan, South China and southern Yunnan; Inserted rice and southern double-season early rice, vegetables, orchards, tea gardens, spring sowing (planting) dryland crops (corn, cotton, peanuts, soybeans, potatoes, spring wheat, sugar cane, sugar beets, sweet potatoes, flue-cured tobacco, miscellaneous grains, etc.) Field water and fertilizer management and pest control; some parts of the southern provinces, cities and towns in flood control (Taiwan), disaster relief or post-disaster recovery, reconstruction, drought prevention and drought relief in some areas of the north; forest and grassland pest control.
This week's focus is on
1. Last week, strong rainfall occurred in the Sichuan Basin, Hanshui River Basin to the northern part of the Yangtze River, Jianghuai and Huanghuai, and the water level in the rivers and lakes increased sharply. Sichuan, Chongqing, Hubei, Anhui, Hunan, Henan, Jiangsu and Shaanxi provinces and cities. Some or part of the area is subject to floods or landslides, collapses, mudslides and other disasters. It is predicted that there will be a strong rainfall process in the eastern part of the Sichuan Basin in the early part of this week, in the north-central part of Chongqing, in the southwestern part of Shaanxi, in most parts of Hubei, in most parts of Henan, in central and northern Anhui, in northern Jiangsu, and in most parts of Shandong. The rainfall in the area generally has heavy rains and partial heavy rains; there will still be a rainy weather process in the Hanshui River Basin, Jianghuai, Huanghuai and other places in the middle and late Zhou Dynasty. The precipitation in the Hanshui River Basin, the Jianghuai River, the Huanghuai River and other places continues to be excessive. The inspection and reinforcement work of the Tanggu and Jianghe Lake dikes should be strengthened, and the farmland ditches should be dredged in time to prevent floods or floods in the farmland, and to prevent mountain torrents and landslides in the mountainous areas. Disasters such as collapse, mudslides, etc. We will also do a good job in disaster relief and post-disaster recovery and reconstruction in the affected areas in the early stage. The flooded crops should be timely protected by seedlings and seedlings, and the dry land crops should be managed in a timely manner by loosening the soil (breaking knots), roots and topdressing, so that they can resume growth as soon as possible; Flooding of severely damaged plots should be carried out in time, and replanting or replanting should be carried out to ensure that the farming time is not mistaken; the harmless treatment of dead livestock and poultry and the environmental disinfection of flooded villages and livestock houses are prevented to prevent the outbreak. ;
2. Last week, most of the three regions in the northeast, north China, and northwestern regions had multiple showers or thunderstorms. The precipitation was unevenly distributed. The average temperature in most areas was close to normal or high in the same period. The light and hot water conditions were basically the growth of crops. favorable. It is predicted that there will be an obvious rainfall process in the eastern and northeastern parts of the North China region in the early Zhou Dynasty. Heavy rains or heavy rains will occur in eastern Hebei, Tianjin, southeastern Inner Mongolia, southern Liaoning, central and eastern Jilin, and central and eastern Heilongjiang. There are heavy rains in the central and western regions, central Jilin, southern Heilongjiang and other places. In the middle and late Zhou Dynasty, the eastern part of the northwestern region and the southern part of North China will have a more obvious rainfall weather process. We should pay close attention to the field management of crops after the rain, timely shovel shovel, topdressing, weeding, timely control of pests and diseases, and ensure the robust growth of plants; prevention of local flash floods, landslides, collapses, etc. in areas where heavy rainfall may occur , low-lying areas should also prevent the occurrence of waterlogging;
3. Currently, it has entered the high incidence period of typhoon. Following the landing of Typhoon "Conson" in Sanya, Hainan Province on the 19th at 19:50 on the 16th, there was a tropical low-pressure formation on the southeastern part of the East China Sea on the 19th, and a tropical low-pressure formation in the eastern part of the South China Sea, and to the eastern part of Hainan. The coastal area of ​​western Guangdong is close to the coast and developed into the tropical storm “Changdu†of the 3rd this year. The coastal areas of South China and East China should pay attention to the movements of these two systems and timely prevent the strong winds and showers;
4. Last week, high temperature weather with a daily maximum temperature of 35-37 degrees Celsius appeared in the south central and southern parts of the south of the Yangtze River, which was unfavorable for early rice filling and late rice breeding. According to forecasts, this week, the central and eastern parts of the south of the Yangtze River and the northern part of South China will continue to have high temperature of 35 days and 37-38 degrees Celsius respectively. Central and western Inner Mongolia, western Gansu, northeastern Shaanxi, northwestern Shanxi, southern Xinjiang and eastern Xinjiang, etc. Some areas of the land will also have high temperature of 35-37 days and 40 degrees Celsius above. The weekend maximum temperature of 35 degrees Celsius or above may occur in parts of central and southern North China, southeastern part of China, and eastern Huanghuai. Hot weather. Farmers and herdsmen friends should do a good job in sun protection and heatstroke prevention in the wild. In the double-season rice-producing area, it is necessary to prevent high-temperature burns of late rice seedlings. After harvesting, early rice should be transplanted to late rice, and deep-water smashing measures should be taken to prevent high-temperature burns. Dry vegetables, melons, or seedlings can be used to reduce the damage caused by high temperature by using shade nets, grass laying or sprinkling irrigation. In the central part of Inner Mongolia, northwestern Shaanxi and other places, we must do a good job in ensuring the farmland to prevent the occurrence of high temperature and accelerate the occurrence or aggravation of drought;
5. Last week, some areas in the northeastern part of the southwestern region had strong rainfall intensity, and the super-alert water level floods occurred in the Jialing River, Minjiang River and Minjiang River, the tributaries of the upper reaches of the Yangtze River. It is predicted that there will still be heavy rainfall in the central and eastern parts of the southwestern part of the country. Some areas such as the Sichuan Basin, Chongqing, northern and western Guizhou, and most parts of Yunnan will have heavy rain or heavy rain. Local torrents or landslides that may be caused by heavy rainfall should be prevented. Disasters such as mudslides;
6. It is predicted that there will be many showers in the Yushu earthquake-stricken area, and some areas are accompanied by thunderstorms and strong winds. Therefore, friends of farmers and herdsmen should do a good job in rain prevention and lightning protection in temporary residential areas, do a good job in strengthening tents and board houses, and guard against landslides, mudslides and other disasters that may be caused by short-term heavy rainfall;
7. At present, the autumn crops in most parts of the country have entered the vigorous growth period, and are in the stage of sufficient heat and precipitation. All localities should carry out scientific field water and fertilizer management according to weather changes and crop growth, and strengthen the monitoring of pests and diseases. prevention, promoting the formation of production, realization autumn harvest;
