Turn on landscape lights at night to extend the day. For plants that have long days and are not very sensitive to sunlight, this will not affect their flowering and fruiting. Because it receives light for a long time, photosynthesis is prolonged, the accumulated nutrients will also increase, and it can become stronger. But for short-day plants, prolonged daylight hours are detrimental to their flowering. When plants carry out photosynthesis, they mainly convert light energy into biological energy and store it. Light is actually light produced by humans. The part of the energy that can be absorbed by plants completes photosynthesis. is far away The temperature is lower than that of the sun and less visible light can be absorbed. It is not easy to build a lawn for a football field at the current level: firstly, thePhotosynthesis is limited by light, resulting in less product, and the grass is often tender and intolerant of trampling.

The trees next to the highway are often very tall. At this time, applying a layer of white lime will play a very good role in keeping warm, which is equivalent to a protective film to prevent damage to trees in winter. There are so many microorganisms and pests around the plants that they are painted with a white layer. Lime water can effectively kill these pests and play a very good role in protecting trees.The other is to avoid exposure to sunlight. The brightest colorThe trunk can easily absorb sunlight and heat. cracking and peeling phenomenon, so painting tree trunks white can effectively prevent heat absorption. A layer of white material is painted around the road, which plays a very good aesthetic role. There are white tree trunks on both sides. the road as far as the eye can see Magnificent!
