The demand for light of orchid cultivation on balcony

Orchids need sunlight to carry out photosynthesis, produce nutrients and promote the development and growth of leaf buds and flower buds, so light is essential for orchids, especially in winter, so as to help orchids survive the cold and winter. orchids' demand for light varies in different seasons, different regions, different varieties and different sexes, such as orchids, cold orchids need less sunlight, spring orchids Jianlan needs less light than Huilan but more than Cymbidium. The light intensity has a great influence on the growth of orchids and the appreciation value of orchids.

[1] the influence of light on leaf color, the light is too strong, the leaf color changes from green to light green, if the strong light is illuminated, the leaf color quickly turns yellow, the leaf surface is rough and even the leaf is scorched yellow, withered, loses the ornamental value, and the light is suitable, the leaf is green and delicate, and the light is too weak, the leaf color is dark green and less glossy, and observe the change of leaf color, which can be used as one of the bases for shading and preventing dryness and dampness, disease prevention and treatment.

[2] the effect of light on bud emergence and growth, the intensity of light has obvious influence on the number, time and growth of leaf bud, the light is weak, more leaf bud and less flower bud, strong light, more flower bud and less leaf bud, too strong light, which is not conducive to the growth of young buds. If you want to have multiple leaf buds, in addition to reducing the light intensity, you can remove too many flower buds, and you can see results in the coming year. Only with moderate light can the orchid grow luxuriantly.

[3] the effect of light on flower color and florescence: when the light of the balcony is stronger and the light time is longer, the flower color is deeper, and vice versa. For example, the color will deepen year by year and turn into golden flowers. Jianlan red flowers are suitable to bask in the sun in summer, so that they not only bloom more, the florescence is earlier, but also the red is darker. If you want to prolong the flowering period, you can put it in a cool place during flowering. Pay attention to less watering.
