What flowers do not require high light intensity? How are they classified according to the light intensity requirements?

"Everything grows because of the sun." The survival of plants is closely related to light. Plants need to metabolize through photosynthesis. Flowers are a member of the plant family. Their growth and development depend on light intensity and exposure time. Related.

According to the different needs of flowers in day length, they can be divided into short-day flowers, medium-day flowers and long-day flowers.

Short-day flowers, such as chrysanthemum and poinsettia. , can only be conceived and blossomed under short sunshine conditions to complete the menstrual cycle. Using this characteristic of flowers, flower shops can control the flowering period according to their own needs, such as shading chrysanthemums during the National Day; Increasing light can also make chrysanthemums bloom on New Year's Day and Spring Festival.

Most long-day flowers bloom in summer, such as lotus and crape myrtle. The sunshine in summer is about 100 days, which is suitable for flowers to bloom.

Zhong Rizhao flower is not sensitive to the length of sunshine. As long as it is properly maintained and grows normally, it can blossom and bear fruit, such as roses, Milan and osmanthus.

Flowers are divided into positive flowers, neutral flowers and negative flowers according to their photophobia and sensitivity to light intensity. Sunflower refers to a flower that likes sunshine. Must be cultivated and maintained in the sun, such as roses, Prynne, Milan, jasmine, chrysanthemum, pomegranate, lotus and so on. These flowers should not be placed in the shade, otherwise the flowers will be elongated, the leaves will become thinner and the leaves will become thinner due to insufficient light. The disease resistance drops, and the flowers can't bear fruit.

Female flowers are shade-loving flowers, such as hawksbill bamboo, cuckoo, orchid, asparagus, fern, dragon's blood tree, brown bamboo, sunflower and so on.

The sun visor can prevent the blade from being burned. At the same time, the air humidity should be appropriately increased. If the shade-loving flowers are exposed to strong light and the ambient air humidity is low, which is very unfavorable for their growth, diseases will occur and eventually they will die.

Through our introduction, I believe everyone has a deeper understanding of what flowers have low requirements for light and how to classify them according to the requirements of light intensity.
