[1]Hot air heater for heating
There are two types of hot air blowers commonly used in the market, electric heat air blowers and oil-fired hot air blowers, both of which can achieve heating effects. But I prefer to use electric heaters, because electric heaters do not have any odor when they are used in the greenhouse. The fuel is different. There will be a smell of fuel, which may affect the growth of crops. Generally, hot air blowers are used for temporary heating, which is very suitable for special cold weather. Hot air blowers are generally very powerful and consume very much energy. There is no long-term use of hot air blowers to heat the greenhouse.
[2] Greenhouse heating block
Some people are relatively unfamiliar with the greenhouse heating block. Its main components are fruit charcoal powder, corn flour, combustion aid, smokeless agent and other synthetic combustion blocks. The heating method is open flame heating. Especially when dealing with the arrival of the cold current, the room temperature will gradually drop. Too low room temperature is detrimental to the growth of crops, and temperature increase measures must be taken. This heating block can be ignited to increase the temperature quickly, and the temperature of the flame is about 500 degrees. Generally, using 3-5 yuan per mu of land can raise the room temperature by about 4 degrees. The need to pay attention to the use of heating blocks is to pay attention to ventilation, because the combustion will cause a lot of carbon dioxide, which is not conducive to growth. Also pay attention to fire prevention. The comparative heating block is an open flame heating method, and it must be kept away from flammable products.
