What seeds will first frost open?

Frost will bloom: cotton, fruit trees, pine nut shells.

The formation of frost is not only related to the weather conditions at that time, but also related to the nature of attachments. When the surface temperature of the object is very low, but the air temperature near the surface of the object is relatively high, there is a temperature difference between the air and the surface of the object. If the temperature difference between the surface of the object and the air is mainly caused by the radiation cooling of the surface of the object.

When hot air touches the surface of a cold object, the air will cool down. Especially after the severe cold and frost, the temperature rises suddenly, and the water oozing from crops will soon turn into steam and disappear. The water lost by cells cannot be recovered, and crops will die. Frost is a weather phenomenon in autumn and winter.

After severe frost, when the temperature rises suddenly, the water oozing from crops will soon turn into steam and disappear. The water lost by cells cannot be recovered, and crops will die. Frost will peel off the shells of cotton peaches. It will also open the shell of fruit tree seeds. Open the elm seed shell.

It is a natural law to reserve food for winter in advance. Five days later, deep in the yard, all the trees turned yellow in the frost at night, and yellow flowers piled on the ground, leaving only the rustling trunk. Timely topdressing and watering can promote the early recovery of damaged wheat seedlings and reduce the loss of frost disaster.
