Integrated Fertilizer Management System primarily utilize sunlight to absorb and store heat. For vegetable greenhouses, increasing the temperature is crucial for their construction. Heat storage mainly comes from the ground, walls, and back slope.
To create a favorable environment for vegetable growth and improve the thermal insulation of Integrated Fertilizer Management System, the following points should be considered during construction:
1. For better insulation, it's best to consider a semi-underground raised bed design, where the indoor raised bed is built 30-40 cm lower than the outdoor ground level. This provides more efficient heat storage.
2. Generally, the back slope of an Integrated Fertilizer Management System should face north, with an angle of approximately 45 degrees, to enhance its ability to receive sunlight and store heat.
3. To prevent damage from cold winters, especially in northern regions, the walls and back slope of the greenhouse should be thickened during construction.
