According to reports, the following methods can be used to supplement the lighting of the shed. First, the use of mechanical shutters can not only save manpower and reduce labor intensity, but also can significantly shorten the time for exposing and covering straw (or insulation) time and effectively extend the lighting time of vegetables in the shed. Second, choose to switch film. It can increase the light intensity in the shed, which is very beneficial to the growth of vegetables in the shed. Third, keep the shed film clean. Clean the dust and dirt from the shelter. Fourth, the ground cover film. Not only is it beneficial to raising the ground temperature and reducing the air humidity in the shed, the reflected light formed after covering the mulching film can also increase the light intensity of the base of the vegetable and make up for the lack of direct light at the base. Fifth, hang a reflective screen. By placing a light curtain on the interior wall of a greenhouse, the light intensity of vegetables near the rear wall can be significantly increased, and the yield of vegetables in the area can be increased. Sixth, artificial light. In case of continuous rain and snow, conditions should turn on the lights or ignite the lights to fill the light.
