Summer Management of Lily
Lily has a variety of flowers, and the flowers are large and trumpet-shaped, and they are widely loved by people because of the meaning of "a hundred years of harmony" and "Pepsi harmony". Summer is the main florescence and dormancy period of lilies, which is very important for its maintenance and management. Cool down and avoid the sun. The suitable temperature for the growth of lily is from 15 ℃ to 25 ℃, which can maintain good growth and flowering. When flowering, the pot plant can be moved to a cool place, or shaded by a curtain on the plant, and strengthen ventilation to cool down, which is conducive to prolonging the flowering period.

Soilless cultivation techniques of Lily
The first condition for the production of high-quality cut lily flowers by lily propagation is that there are robust and disease-free bulbs. The propagation of lily (or "seed ball production") can be divided into post-anthesis bulb culture, bulblet propagation, scale cutting, bulb propagation, sowing and tissue culture. This paper introduces several main methods of reproduction. (1) raising balls after anthesis is also called big ball breeding. When the lily begins to blossom, a new bulb has formed in the ground, but it has not yet leapt into a mature "big ball". Therefore, when harvesting cut flowers, it is necessary to ensure the branches of flowers.
