Sedum lineare cultivation substrate for light roofs and method for preparing sedum lineare cultivation substrate

Abstract

The invention discloses a sedum lineare cultivation substrate for light roofs. The sedum lineare cultivation substrate comprises soil layers, substrate layers, planting layers and hydrophobic layers. The soil layers comprise, by weight, 25-40 parts of peat soil, 10-20 parts of loam, 5-15 parts of clay, 2-10 parts of pearlite and 15-25 parts of organic matters; the substrate layers comprise, by weight, 45-60 parts of humus soil, 1-5 parts of pearlite, 1-5 parts of coconut coir, 0-5 parts of 45% three-element compound fertilizers and 1-8 parts of organic matters; the planting layers comprise, by weight, 8 parts of humus soil, 1 part of pearlite, 1 part of coconut coir, 10-15 parts of peat soil, 3-10 parts of rice hull, 1-5 parts of bentonite, 5-10 parts of shell powder and 0-3 parts of urea; the hydrophobic layers comprise, by weight, 50-70 parts of gravel, 8 parts of humus soil, 1 part of pearlite and 1 part of coconut coir. The sedum lineare cultivation substrate has the advantages that the sedum lineare cultivation substrate is a mixed substrate, and a method for preparing the sedum lineare cultivation substrate is simple; the growth rate of sedum lineare can be increased, root rotting and seedling burning phenomena of the sedum lineare can be reduced, and the weather resistance of the sedum lineare in high-temperature and high-humidity environments can be improved.

Description

technical field [0001] The invention relates to the field of cultivation of S. argentina, in particular to a substrate for cultivating S. argentina on light roofs and a preparation method thereof. Background technique [0002] With the development of urban ecological construction, roof greening has been highly valued by all walks of life, and even some countries regard roof greening as a rigid index of buildings, hoping that roof greening can eliminate the increasingly serious urban "heat island" effect. At present, the most commonly used roof greening plants are S. japonica, also known as Wanniancao, which is a perennial herb of Crassulaceae. The stratum corneum has the property of preventing moisture from evaporating. Its growth adaptability is extremely strong, cold-resistant, drought-resistant, salt-alkali-resistant, neat and beautiful, it can be used as a potted plant for appreciation, or it can be planted as an open-air ornamental ground. [0003] At present, commonl...

AI Technical Summary

Problems solved by technology

[0003] At present, commonly used substrates for cultivating S. argentina mainly include common substrates such as peat, grass ash, pond mud, sand, mushrooms, etc. Using this substrate, S. argentina grows better in spring and autumn, but if it is a high temperature season in summer, it often appears The phenomenon of rotten roots of S. chinensis is not only slow in production, but also easy to die. Now we need a cultivation substrate for S. sagerae. It is expected to improve the growth efficiency of S. sagerae and reduce the phenomenon of rotten roots and burning seedlings through the improvement of the substrate formula.
