First, avoid leaks carefully check the plastic film and find that the holes and cracks are repaired immediately. The plastic film laid on the ground should be firmly bonded with clay. This will prevent cold air from entering the shed.
Second, the straw canopy cover straw, corn, wheat straw and other crop stalks into the straw, as long as there is no sun to cover the shed above; see the sun, timely removal of straw. When the temperature drops suddenly, it is also possible to cover the straw with a plastic film. Since the straw curtain is a poor conductor of heat, heat loss in the shed can be reduced and the temperature can be reduced.
Third, the shed built shed due to the growth of vegetable seedlings or weak seedlings in the greenhouse, poor cold resistance, bad weather, the seedlings or weak seedlings on the vegetable pods, and then build a plastic shed. In this way, the vegetables in the shed are protected by a double-layer film, which can prevent seedlings and weak seedlings from freezing.
IV. Irrigation Before the cold current hits, irrigation of the vegetables in the greenhouse can increase the temperature of soil and air in the greenhouse. This is because the heat capacity of the water is so large that even if the cold currents invade and the temperature suddenly drops, the water in the greenhouse is frozen and freezes, and a lot of heat needs to be absorbed. Therefore, the temperature inside the greenhouse will not drop too much, and it can guarantee the inside of the greenhouse. The normal growth of vegetables.
Fifth, heating up the fire to a small area of ​​greenhouse, in the cold or frost to come, you can produce a stove in the greenhouse, the use of heat emitted by the fire to increase the temperature inside the greenhouse, thus playing a role in antifreeze.
Before the advent of the cold winter smoke stream, crop stalks, firewood, etc. were ignited around the outside of the greenhouse. The smoke generated by the smoke was used to drive out the cold, so that the temperature around the greenhouse increased, thus ensuring the temperature in the greenhouse was increased and the purpose of resisting cold current was achieved.
Seventh, when the heater blows hot wind and cloudy or poor lighting, the heater can be set temporarily in the shed. It should be noted that it is best to use a bathroom heater. This is because the humidity in the booth is too large. Using an ordinary heater, electric leakage is likely to occur. At the same time, the heater outlet should not be directly facing the plants. In order to avoid hot air temperature is too high, damage plants.
