Requirements of different flowers for light intensity: Due to the influence of illumination conditions and genetic factors of origin, different flowers have different requirements for light intensity. According to their different requirements, they can be generally divided into: positive flowers, neutral flowers and negative flowers.
Positive flowers. The normal growth of these flowers requires sufficient light intensity, and is most suitable for growing in a full-day environment. They can not stand any significant shade. Even in hot summer, they need sufficient sunshine. These flowers do not need shade nets to shade.
Neutral flowers. This kind of flower has a wide range of adaptability to light intensity. Generally, it needs sufficient light to grow strong. It also has a certain shade tolerance, but it does not grow well when shade and light are too weak. There are many kinds of flowers planted in families, and the shading requirements are different. Therefore, it is impossible to adopt a variety of specifications. Usually, 50%~60 shading net can be used.
Negative flowers. Such flowers need certain shade conditions to grow normally, but can not adapt to the strong light environment; when the sun is too strong, chlorophyll will be destroyed, plant growth is poor, resulting in yellowing of leaves.
