Mid-October in the north, the weather is favorable for agriculture, South China, guard against heavy rain and cold wind
It is expected that in mid-October, there will be cooling and precipitation weather in the middle and lower reaches of the Yangtze River and north of China, but there will be no adverse impact on the harvest of autumn harvest crops in Northeast China, North China and Huanghuai. The southeastern part of the northwestern region and the southwestern part of North China have more precipitation, which is not conducive to crop harvesting; Hainan will still have strong precipitation weather in the coming week, which is not good for late rice harvest.
Most weather conditions in Northeast China, North China, Huanghuai and other places have no adverse impact on autumn harvest.
From October 12 to 15, due to cold air, China's middle and lower reaches of the Yangtze River and its north will have a temperature drop of 4-8 °C. In most of the central and eastern regions, there is a precipitation process, mainly from small to moderate rain. Rainfall weather can increase the soil moisture in the winter wheat planting area in the north, and has no adverse impact on the harvest of autumn harvest crops in northeast, north China and Huanghuai.
There is more precipitation in the southeastern part of the northwestern region, which has a slight impact on the autumn harvest.
It is expected that in mid-October, there will be more precipitation in the southeastern part of the northwestern region and the southwestern part of North China, which is not conducive to crop harvesting. At the same time, the soil in the early stage is too wet, and the rainy weather is unfavorable for soil divergence and autumn sowing.
Some parts of southern China will be affected by low temperatures, heavy rains and tropical cyclones
It is expected that there will be cold weather in some areas of northern China from the 14th to the 16th, which will have an adverse effect on some late rice that will be heading and flowering. In the coming week, Hainan will still have strong precipitation weather, which is unfavorable for late rice harvest; in the middle, there will be 1~2 The formation of a tropical cyclone may affect agricultural production in the coastal areas of South China and Hainan.
Precipitation in the southwestern dryland is conducive to further easing of the drought
In the middle, the cumulative precipitation in southern Sichuan and southwestern Guizhou is 10 to 20 mm, and the local area is 30 to 40 mm. Precipitation will further improve the soil moisture, which is beneficial to the emergence of autumn and autumn-sown crops.
Concerns and suggestions
In the northern region, it is necessary to catch the fine weather and harvest the mature crops in time; the areas that are suitable for the winter wheat sowing period should be planted at the right time; the areas with more precipitation should pay attention to timely divergence.
Late rice in South China is in a critical period of production formation. All localities need to strengthen field management to prevent the adverse effects of cold dew; Hainan should pay attention to the adverse effects of heavy rain.
The southwestern arid area should seize the opportunity of precipitation, planting winter wheat, rapeseed and other autumn sowing crops, and do a good job of water storage.
