Background technique

Vegetable planting is a labor-intensive and technology-intensive industry. It has unique advantages and status in my country's agricultural development. Vegetables are one of the most dynamic economic crops in the planting industry and one of my country's agricultural products with strong international competitiveness. Its export volume accounts for about 4% of the world's export trade volume. According to statistics, 15% of the current vegetable supply comes from greenhouse vegetable cultivation.

In some areas in northern my country, winter is relatively cold, and most winter vegetables are planted in greenhouses (greenhouses). One of the most important technologies in greenhouse vegetable cultivation is irrigation technology. Generally speaking, groundwater should be used for irrigation in winter greenhouses, and the water temperature should be Not lower than 2-3 ℃; do not directly use river water, reservoir water and cold water in ponds for irrigation. For areas where the groundwater temperature is too low, two methods are currently used to heat up the irrigation water, namely, natural heating and forced heating. Natural heating means that the irrigation water is introduced into the water tank in the greenhouse, and the irrigation water in the water tank is naturally heated by heat transfer through the temperature of the greenhouse. However, the heating speed of this method is slow, and it is easy to reduce the temperature in the greenhouse, which increases the overall energy consumption of the greenhouse. , or affect the stability of the temperature in the greenhouse, which is not conducive to the healthy growth of vegetables; forced heating refers to the use of heating devices to heat up the irrigation water. These heating devices consume high energy, which is not conducive to energy saving and emission reduction.
