Background

China is one of the origins of China. China rose is honor, beautiful and has various postures, is always open in four seasons, is deeply loved by people, is usually used as ornamental flower seeds by people, and is usually planted in a greenhouse on a large scale at present. China rose is a plant which is loving light, and most varieties can grow well only in a space with good illumination environment. Without sufficient illumination, the photosynthesis rate of the Chinese rose is low, the organic matters cannot be effectively synthesized to exchange nutrition with roots, and the Chinese rose can generate the phenomenon of malnutrition after long time.

Generally, people adopt a full-sunlight mode to cultivate the Chinese roses, but in south areas, the illumination is strong in summer, and particularly in the noon, the strong sunlight can aggravate the transpiration of the Chinese roses, so that the Chinese roses wilt. Even for heat-resistant rose varieties, the growth of roses may be inhibited by too high a temperature, causing them to enter a semi-dormant state.

Usually, people set a sunshade net on the Chinese rose, and the distance between the sunshade net and the Chinese rose is kept above 80cm, so that the Chinese rose is shaded, and the sunshade net is removed after the sunlight is weakened.
