The harm of peach blossom snow

The hazards of peach blossom snow are: it will adversely affect the fruit trees entering the flowering period, and the fruit trees are easy to drop flowers and fruits. In order to prevent crops from freezing or promote the rapid recovery of frozen crops, we can spray "potassium dihydrogen phosphate+brassinolide" in agricultural production to enhance the cold resistance of crops, which can effectively reduce losses.

As the agricultural proverb goes, "Peach blossoms and snow in March, clear and less cold in spring". The meaning of this agricultural proverb is simple. It means that if it snows in March, according to the experience of our ancestors, the probability of cold weather in Tomb-Sweeping Day is very low. Generally speaking, the later the late spring cold comes, the greater the harm to crops.

Qingming Festival is the growing period of seedlings and the sowing time of spring corn. In the event of late spring cold, seedlings are frozen, resulting in rotten seeds not unearthed, leading to a large number of fruit trees lodging, which can be said to be extremely harmful to crops. Therefore, the "cold spring in April" is a phenomenon that farmers are very unwilling to see.

Now is the solar term shock, rape and peach blossom are in full bloom. As the saying goes, "a child's face changes three times a day." The weather is warm and cold in early spring, and there are often cold waves (cold in late spring). The snowfall in Henan in these two days is the result of the combined action of strong cold air and warm and humid airflow. In the precipitation stage, snow will form with the further decrease of temperature, which can be said to be a very normal phenomenon, not an abnormal phenomenon.
