The role of agricultural proverbs in agricultural production;

1, agricultural proverbs can help farmers better predict weather and climate change. For example, the proverb "Don't go out at sunrise, travel thousands of miles at sunset" can predict the future weather according to the color and distribution of clouds in the sky, thus helping farmers make good farming arrangements.

2. Agricultural proverbs can guide farmers to carry out reasonable agricultural activities. For example, the proverb "Before and after Tomb-Sweeping Day, plant melons and beans" tells farmers that before and after Tomb-Sweeping Day is the best time to plant melons and beans, thus helping farmers to arrange their planting plans reasonably.

3. Agricultural proverbs can also remind farmers to pay attention to agricultural safety and the prevention and control of crop pests and diseases. For example, the proverb "Sleeping in straw, pests and diseases will go to hell in the coming year" tells farmers that burning straw in winter can reduce the occurrence of rice pests and diseases in the coming year.

4. Agricultural proverbs can inherit and carry forward agricultural culture. These proverbs not only reflect the wisdom and experience of farmers, but also contain rich cultural connotation and humanistic spirit. By inheriting and carrying forward these proverbs, we can better understand and inherit agricultural culture and promote the sustainable development of agriculture.
