The key to successful greenhouse cultivation lies in the scientific control of temperature, light, and humidity to ensure crops grow in the most suitable environment.
Light Management: Maximize Light Energy by Choosing High-Transmittance Covering Materials
Using PVC drip-free long-life film or anti-reflective glass can increase light transmittance by 20%–30%, especially suitable for the low-light winter season.
Keep the Film Clean
Dust, water droplets, or snow on the film can reduce light transmittance by 30%–50%. It is recommended to clean the film surface with a soft cloth after uncovering the curtains daily and remove snow promptly.
Enhance Light Distribution Uniformity
Hanging an aluminized reflective screen on the back wall of the greenhouse can increase ground light by more than 20% and raise ground temperature.
Laying silver-gray reflective film on the ground helps improve light exposure to lower leaves and promotes fruit coloring.
Rational Layout and Planting Structure
Follow the "high in the north, low in the south" principle. Plant fruit and vegetable crops (such as tomatoes and cucumbers) on the north side and leafy vegetables on the south side to reduce shading. The beds are laid in a north-south direction, with wide and narrow rows for planting, which improves the overall light-gathering efficiency.
