To avoid light and frozen vegetables can not immediately receive light, the use of grass curtains and other objects covered in the film on the studio, but also can be used to cover the frozen vegetables such as newspapers and other opaque substances, so that frozen vegetables slowly thaw and restore growth.
Slowly increasing the temperature in the frozen vegetable sheds is not allowed to thaw using rapid temperature rising measures. In addition to shading, appropriate measures such as air release may be taken to slowly increase the temperature of the shed.
After the vegetables are frozen, they can be watered in an appropriate amount. It is also possible to use a sprayer to spray 800 times of new high-fat membranes on the vegetables and the ground immediately after freezing to prevent the ground temperature from continuing to fall and the dehydrated and frozen vegetables from drying out.
After spraying and preventing diseased vegetables from freezing, the growth is weak, and diseases such as gray mold are easy to occur. After the vegetables grow up, cut off the frozen parts, and use the new high-fat film 500 times solution and 50% quick-acting agent. Wet powder 2000 times spray, can also be smoked with 10% fast-king smoke agent.
Strengthen management After the frozen vegetables are restored to growth, they should be prevented from re-freezing, and loosen the soil in time, apply the appropriate amount of fertilizer quickly, and promote plant growth.
