Novel domestication method for roof greening sedum lineare

Abstract

The invention relates to the technical field of plant cultivation, and particularly discloses a novel domestication method for roof greening sedum lineare. The novel domestication method comprises the following steps: selecting robust sedum lineare in good variety as grass seeds, and selecting luxuriant sedum lineare seedlings after broadcast sowing and reproduction; and then preferably using a culture medium to continuously cultivate and carry out domestication (such as drought resisting, cold resisting and insect resisting) on the sedum lineare seedlings, and finally selecting out the sedum lineare seedlings which are excellent in properties (such as drought resistance, cold resistance and insect resistance) and are suitable for roof greening. The sedum lineare obtained by domestication method of the present invention has drought resistance, cold resistance, insect resistance, and tenacious vitality, seedlings are high in survival rate and uniform and neat, the root system is high in fixing force, and surface soil can be prevented from being washed away by rainwater. The sedum lineare is used for roof greening, having effects of insulating and saving energy, purifying air and removing haze, preventing waterlogging and reducing emission, protecting a roof, beautifying the environment and the like, and has the features of good landscape effect, easiness in maintenance, low cost, quick effect and the like.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a domestication method of a novel roof greening Sageria. Background technique [0002] Sedum lineare Thunb belongs to the perennial herbaceous plant of Crassulaceae, the stem is succulent and succulent. Most are clustered, the stems are slender and recumbent, and the prostrate parts take root in joints. The leaves are thick and oblong, with three whorls. The leaves are about 20mm long, 7mm wide, and 0.7mm thick. In early summer, the branches bloom, yellow, with five petals, and the same number of stamens and petals. [0003] It is a succulent evergreen plant with high water content and excellent drought tolerance. The cuticles of its leaves and stems have extraordinary characteristics of preventing water evaporation, even in summer drought. It can still maintain a vibrant green color without watering under certain conditions, and its drought tolerance can last up to ...
