After the seedlings are released, the seedbed should be ventilated, and the ventilation should be gradually increased as the weather warms up. The seedlings are subjected to low temperature exercise to improve the cold resistance of the seedlings and adapt to the outdoor low temperature environment.

How to prevent cold spring?
Adding protection facilities and adding protection facilities can be done in two ways: one is to set up wind barriers. The wind barrier blocks the cold air and prevents the surface from further cooling. The second is to plant the ditch and cover the mulch. When planting vegetables in early spring, the method of ditching and planting can be adopted. The depth of the ditch should exceed the height of the seedlings, and then the mulch can be covered on the ditch.
Temporary warming and protection of production, in the cold stream, can be temporarily warmed in the nursery shed or production shed by means of a simple coal stove or installation of electric lights to improve the temperature inside the shed and prevent freezing damage.
When the well water is poured, the weather is fine, there is no wind or breeze at night, and the temperature drops rapidly. Especially when the local table temperature drops below 0 °C, the well water can be poured on the ground to greatly increase the water. Geothermal. This method can raise the ground temperature from 0 °C to about 8 °C to avoid frost.
Smoked frosty nights, smoked in the field can effectively reduce or avoid frost disasters. However, we must pay attention to two points: First, the fireworks point should be properly dense so that the smoke screen covers the whole garden; second, the ignition time should be appropriate, and should be ignited in the upwind direction from midnight to 2 o'clock in the morning until the sunrise, there is a smoke curtain On the ground, this works best.
Appropriate amount of water spray Before the frost occurs, spraying the surface of the plant with a sprayer can slow down the body temperature, and also increase the water vapor content in the atmosphere, and the water vapor condenses and releases heat to alleviate the frost damage.
Timely cultivating and cultivating before the frost can reduce the degree of frost damage. Because the temperature in the spring gradually rises, after the earthworms are loosened, the solar heat energy can be absorbed and stored more. Once the frost damage occurs, the frost can be alleviated because a part of the heat has accumulated in the soil.
