Agricultural activities of heavy snow and solar terms

1. Protect farmland: In the snow season, it is necessary to protect farmland from severe cold weather and disasters. Farmers can use the water around the farmland and the snow in the farmland to keep the soil moist and warm. At the same time, it is necessary to repair the dams and drainage systems of farmland in time to prevent the fields from being flooded by accumulated water.

2. Weeding and weed treatment: Weeds in farmland should be cleared before winter comes. In particular, some roots and grasses that are difficult to remove must be thoroughly removed to ensure the quality and effect of spring sowing.

3, pest control: farmers also need to pay attention to whether crops are attacked by pests and diseases, and take corresponding prevention and control measures. Organic fertilizer can be used to improve the soil, improve the ability of crops to resist pests and diseases, and at the same time strengthen observation and inspection, and deal with problems in time when found.
