How to reduce the humidity of greenhouse vegetables
One is to choose a no-drop film. The use of a non-drip film can reduce the amount of water accumulated on the surface of the film, and is conducive to light transmission and temperature increase. The second is to cover the mulch. Since the mulch film is not permeable, the amount of surface water evaporation and irrigation can be reduced, thereby achieving the purpose of reducing the humidity of the air in the shed. The third is reasonable watering. Watering the shed in winter, you need to do “five pouring and no pouringâ€, that is, watering on sunny days, not watering on cloudy days, watering in the afternoon, not watering in the afternoon, pouring small water, not flooding, pouring warm water, not Pour cold water, pour dark water, and do not pour clear water. The fourth is to improve the application method. In the winter, the vegetable pests and diseases in the greenhouse should be used as much as possible by the smoke method or the dust method. If the spray method is applied, the number of times of prevention and the amount of liquid spray should be appropriately reduced to prevent the humidity in the shed from being too high. The fifth is artificial moisture absorption. If the humidity in the shed is too large, you can sprinkle some straw, grass ash or fine dry soil between the rows. You can also absorb hygroscopic materials such as quicklime in the free space of the shed to absorb moisture. Disclaimer: Some articles on this website are transferred from the Internet.

Through a small handrail, create a safe and secure living environment for the elderly at home. When installing the handrail, pay attention to determine the installation height of the handrail according to the height of the elderly at home. The armrest is located at the crotch of the elderly. Generally speaking, it is about 80 to 85 cm from the ground. In order to provide safe and effective support for the elderly, different products need to be selected according to different installation conditions. Some families want to install handrails on non-load-bearing walls. We suggest that they install lining plates first, and then install handrails on the lining plates.
When selecting the material of the handrail, pay attention to the coordination with the furniture environment, create a warm atmosphere, avoid making it cold and hard, and do not give the elderly the illusion of "being a patient". For example, the wooden handrail in the video looks very warm and feels good. It is suitable for the elderly.
