Most of the agricultural areas in the next three days will suffer adverse effects due to rainfall and autumn harvest.

China Xingnongwang reported on October 11 that recently, most of the country’s agricultural areas had better weather conditions, and the autumn harvest progressed rapidly. According to statistics of the Ministry of Agriculture, as of October 10, the harvested area of ​​the national harvest crops has exceeded 70%, reaching 855 million mu, and the progress is 6% faster than the same period of last year. In the country, 204 million mu of autumn and winter crops have been planted, and 28.4% of the plan has been completed. The progress is normal.

The winter crops in Xinjiang, the eastern part of the northwestern region, North China, and Huanghuai are in the stage of seedling emergence, and part of the crop is paralyzed; the rapeseed in the Yangtze River Basin is in the seedling emergence stage, and some regions enter the fifth true leaf stage.

It is expected that in October, the precipitation in the eastern part of the northwestern region, central and southern part of northern China, and the southern part of the northern part of the year are more than normal, which is not conducive to the harvesting and drying of crops harvested in autumn. At the same time, soil moisture in some areas will adversely affect the timely sowing and emergence of winter wheat. The rainfall in October in the arid area of ​​southwest China is still dominated by less precipitation, and the temperature is higher, and the drought in some areas may develop again, which is not conducive to autumn sowing. In addition, heavy storms caused by tropical cyclones may affect agricultural production in coastal areas.

Recent Weather Impact on Autumn Harvest Autumn crops From October 8th to 11th, sunny weather in most parts of the country is conducive to the harvesting of autumn crops and the autumn harvest. In the northwestern region of the northwest, southwestern China, southwestern Jianghan, northeastern Jianghan and northeastern parts of the country, small-to-medium-day rains have occurred for 1-3 days, and snowfall has occurred in northern Xinjiang, which has caused adverse effects on the autumn harvest; Increasing soil moisture is not conducive to autumn sowing.

At the end of September to October 8th, mild to moderate “cold dew” weather occurred in 3 to 8 days in most Jiangnan and South China, which was unfavorable for pollination of late rice in southern Jiangnan and northwestern parts of South China during the heading and flowering stage; October 9th. The cold dew weather is basically over, which is conducive to the development of late rice.

The possible impact of future weather on autumn harvest is expected from October 12 to 14, except in Xinjiang, the northeastern part of Northeast China, northern Shanxi Province, and the east coast of Shandong Province where the weather is good, most of the other major agricultural areas in the country have more rainfall. Harvesting and drying of autumn crops will be adversely affected.

It is expected that in the winter from October 12 to 14, the eastern part of the northern winter wheat region will be dominated by fine weather, which is more suitable for the sowing and seedling growth of the winter wheat; the rainy weather in the west may affect the planting schedule. Most of the Yangtze River basin and the eastern part of the southwestern region will have a precipitation process, mainly from small to moderate rains, with little impact on sowing and seedling growth; heavy rain will occur in some parts of the south of the Yangtze River, which is unfavorable for rapeseed sowing.

It is expected that frost will occur in central and eastern parts of Inner Mongolia, parts of central and western Heilongjiang, and parts of northern Hebei from October 12 to 14, and the harvest crops in most of these areas have matured. Frost has no effect on crop yields.

It is expected that from the 13th to the 14th of the month, the average daily temperature below 22°C will occur in southwestern Jiangnan and parts of the northeastern part of South China, which is somewhat detrimental to the pollination of late rice still in the stage of heading and flowering.

Suggestions for Agricultural Production First, the agricultural areas in the north have to pay attention to the ventilation and sheltering of the harvested grain, so as to avoid the occurrence of mildew and spoilage.

Second, the winter wheat fields in the north and the rapeseed production areas in the Yangtze River Basin should use clear weather gaps to rob and rush when they are planted to ensure the quality of sowing and the sowing schedule, and ensure that the autumn sowing is completed within the appropriate sowing period.

Third, the management of late rice growing areas in the south should be strengthened to ensure adequate grouting of late rice and promote high yields.
