Climatic characteristics of autumnal equinox season

In the autumn equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, which causes repeated precipitation and the temperature drops again and again. As people often say, it's time for "an autumn rain and a cold", but the daily precipitation after the autumnal equinox will not be great. At this time, the field farming in the south and the north is different.

The autumnal equinox means really entering autumn. Due to the cold weather in the northern hemisphere, geese, swallows and cuckoos began to fly in droves from the gradually cold north to the south.

Beginning of Autumn

"beginning of autumn, here we are."

Frost's Descent

It ends in autumn, and the "autumnal equinox" is exactly half of the 90 days from beginning of autumn to the first frost. At the autumnal equinox, the Yangtze River basin and its vast northern area have entered autumn, and the daily average temperature has dropped below 22℃.

The cold air mass in the north began to have some influence. In most areas, the rainy season has just ended, with a cool breeze blowing gently, the sky is high and the clouds are light in Wan Liqing, the air is crisp in autumn, the sweet-scented osmanthus is fragrant, the crab is fat and the chrysanthemum is yellow, and the autumn equinox is a beautiful and pleasant season. It is also an important solar term in agricultural production. After the autumnal equinox, the direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, while the ground lost more heat and the temperature dropped significantly.

Main agriculture:

First, the management of water slurry should be strengthened in the later stage of mid-season rice, and dry-wet alternate irrigation technology should be adopted. Water should not be cut off prematurely before harvesting, and it is advisable to cut off water for 5-6 days before harvesting. This can improve root activity, raise roots and protect leaves, and prevent premature aging and withering.

The second is to pick new cotton in time by stages, and adhere to the principle of "four points and four speeds", that is, separate harvesting, separate drying, separate storage, separate selling and quick harvesting, quick drying, quick picking and quick selling, so as to improve the quality.

The third is to make an autumn sowing plan and adjust the surplus and deficiency of autumn sowing seeds. Before sowing, the seeds of Sanmai and Vicia faba should be carefully selected and treated, and the germination test should be done well. Rapeseed beds should be carefully prepared and sown before the end of September. Seedbed management should be strengthened when sowing rape.

Fourth, plant chrysanthemums, spinach, garlic, autumn potatoes, onions, vegetables, cattail pollen, soybean sprouts and so on. Strengthen the field management of field vegetables, and extend the harvest period and supply period. Harvest water chestnut, lotus root and water bamboo.

Fifth, livestock breeding in autumn, continue to process and store green roughage. Poultry hatch in autumn. Carry out autumn epidemic prevention for livestock and poultry. Strengthen the management of adult fish culture, prevent and control fish diseases, increase concentrate, promote the rapid growth of adult fish, and catch by stages.
