The second is the use of non-drip films. Several drops of active agents are added to the formulation of the dropless film, which greatly weakens the affinity between water molecules and the film, and water droplets flow into the ground along the film surface without water droplets. The use of non-drip film buckle shed can increase the light intensity in the shed and increase the shed temperature.
The third is to keep the shed film clean. Dirt and other debris on the film will reduce the light transmittance by about 30%. Therefore, the dust and dirt on the shed surface should be cleaned frequently to increase the transparency of the shed film.
The fourth is to reasonably cover the straw curtain. On the premise of doing a good job in heat preservation, removing the straw curtain and delayed cover for heat insulation as early as possible can extend the light time and increase the amount of light. Generally, the curtain is opened 0.5 to 1 hour after the sun comes out, and the curtain is covered half an hour before the sun sets. Especially in the rainy days when the rain stops, it is also necessary to unveil the curtain properly to make full use of the sun's scattered light.
The fifth is to set up a reflective screen. Hanging an aluminum-coated reflective screen with a width of 2 meters and a length of 3 meters on the north side of the greenhouse to make it vertical, can increase the ground by about 40%, and increase the temperature of the greenhouse by 3 ° C to 4 ° C. In addition, laying silver-gray film on the ground can also increase the light intensity between plants.
