What is the solar term on the sixteenth?

April 9 ~ 16, moderate rain and heavy rain were confirmed, lasting for 8 days. Is this cold in the spring? Agricultural proverb: Irrigation is better than flood in Grain Rain season.

Grain Rain is one of the traditional 24 solar terms, and it is also a critical period for crop growth in spring. In Grain Rain season, the weather is changeable, the temperature is getting warmer and the rainfall is increasing, which also makes the irrigation and drainage work of farmers in agricultural production more important. "Irrigation should not be flooded" has become an important principle for farmers in this period.

It means that in Grain Rain season, farmers need to pay attention to timely watering to prevent drought and water shortage, and at the same time avoid crops from waterlogging and flood disasters.

Spring is the key period of crop germination and growth, and moderate irrigation can provide sufficient nutrition and water for crops, promote growth and improve yield and quality. However, excessive irrigation or unreasonable drainage will easily lead to crops rotting due to stagnant water or being attacked by pests and diseases, thus affecting yield and quality.

In addition, "suitable irrigation without flooding" also involves the rational use of water resources. In Grain Rain, when there is enough rain, farmers can collect water for use in drought. Farmers should reasonably consider the irrigation amount according to the land conditions and crop demand, choose the best irrigation method, and improve the efficiency of water resources utilization.

To sum up, the principle of "suitable irrigation but not flooding" in Grain Rain emphasizes the importance of irrigation and drainage in agricultural production and the rational utilization and protection of water resources. Farmers need to carry out irrigation and drainage according to their own actual conditions to ensure the good growth of crops and lay a good foundation for a bumper harvest.
