Henan rainy days affect crop growth, pay attention to drainage and drying

At present, only the south of Henan Province and the southwestern part of Henan Province have matured in summer, while most other areas are still in the milky stage, and the first season of Huainan is in the mature stage. As of September 16, the province has not yet started autumn harvest.

It is estimated that on the 17th and 18th, there will be light rain on cloudy days in the province, and moderate to heavy rain and partial heavy rain in parts of the central and western regions. The northerly winds of the province are gradually reduced to 4 to 5 levels, and the temperature will drop significantly. On the 19th, there was light rain in the south and partial rain. In other areas, the rain stopped turning cloudy.

Agricultural production advice:

(1) The soil over-wet plot should be drained and dried as soon as possible after rain, especially in the parts of western Henan, Henan, northwestern Henan and southwestern Henan. The precipitation will be large after rain, and the water in the field should be removed in time to prevent the occurrence of water in the field. Waterlogging affects yield.

(2) In the next three days, the province will have a northerly wind of 4-5 grades. All localities should strengthen the field management of corn, and remove the corn sakura to reduce the wind resistance and reduce the lodging.

(3) Cotton fields should be pruned in time to improve the ventilation and light transmission conditions, and timely picking to prevent rain from affecting the quality of cotton fiber; pay attention to the prevention and control of pests and diseases.
