What is the best way to heat a greenhouse in winter? (The most economical way to heat a greenhouse)

In winter, greenhouse vegetable cultivation may occasionally encounter extremely cold weather, and rain, snow, and cloudy weather are common. Although leafy vegetables have a certain degree of cold resistance, nightshade vegetables have higher temperature requirements. However, when the temperature is low, they will stop growing, and in severe cases, they will suffer frost damage.

Commonly used warming methods

Covering with quilts, setting up double film, alcohol stove, fluorescent lamp, etc. , these are common warming methods, which are used in cold greenhouses and warm greenhouses.

The two methods of using alcohol stoves and fluorescent lamps are more cost-effective . It only costs about ten yuan a night in a greenhouse of seven or eight acres. The warming effect is also acceptable. Under normal weather conditions, you can choose one of these two methods to increase the temperature.

New heating equipment to increase the temperature

Extreme weather is unavoidable in winter, especially at night. The lowest temperature reaches zero degrees, or some greenhouses are large, and some conventional heating methods cannot quickly increase the temperature. At this time, we need to use other heating equipment, such as heating blocks, heaters, and electric boiler heating methods .

Heating block

Generally, three or four heating blocks are needed in a greenhouse, and it takes one or two hours to heat up. It is suitable for small greenhouses, and the cost is 20 to 30 yuan per night. Compared with corn cobs for heating.

Burning warming blocks is a safe method that does not affect crop growth . However, it is not suitable for large and high greenhouses. Even if the amount is increased, the warming effect may not be achieved, and it will cost more money.

Heater

Some heaters use diesel fuel, and the sizes of heaters vary . For example, a 30-kilowatt model can raise the temperature by 8 degrees Celsius overnight, and the rate of increase is also very fast, and the temperature can be raised within an hour.

However, using diesel also has disadvantages. Burning a large amount of oil will release carbon dioxide and carbon monoxide. In the greenhouse, only oxygen and carbon dioxide are beneficial to plant growth, and excessive carbon monoxide will also inhibit plant growth.

In addition, there is another type of electric heater, which heats up quickly. A 20-kilowatt heater requires 20 degrees of electricity per hour. Different sizes have different power consumption.

Combining the advantages and disadvantages of the heater, it heats up quickly and consumes a lot of energy. When extreme weather comes, this method is suitable to quickly increase the temperature without producing a large amount of harmful gases.

Warm Tips : Each heating method has its own advantages and limitations. Farmers can choose different heating equipment according to actual conditions, saving money while ensuring the growth of crops and keeping the night temperature in the suitable growth range for vegetables .
