Embodiment 1

[0017] In May 2013, in the plant planting base of the scientific research area of ​​the South China Botanical Garden, the perennial (more than 2 years) calla lily stems (more than 5cm in diameter) were cut to obtain 40 short segments of about 15-20cm, which were placed horizontally 40cm×35cm×7cm planting baskets with holes at the bottom, put 4 to 5 stem segments in each planting basket, and propagate 9 pots in total, with humus: river sand according to the mass ratio of 3-4:1 for cultivation The substrate should be covered with soil. The thickness of the soil layer should not be too thick, preferably 2-4cm. The stem part that is too thick, such as the stem part with a diameter of more than 20cm, does not need to be completely covered. Water and moisturize, and the shading rate of the frame is 40%-60%. Shade it with a shade net, and transplant it after the young plants germinated from the short nodes grow to 3-4 true leaves (about 30 days). When transplanting, choose a rectangu...

Abstract

The invention discloses a quick roof greening method. The method includes: a, using plants of Alocasia macrorhiza to green a roof; b, cutting each Alocasia macrorhiza rhizome more than 5cm in diameter into 15-20cm short sections, placing the short sections in a planting sieve or pot, covering with culture medium made of mixture of humus and river sand in the mass ratio of 3-4:1, making sure that a soil layer is 2-4cm in thickness, not fully covering stalks more than 20cm in diameter, sprinkling to preserve moisture, setting up a shade net for shading and accelerating quick germination, and transplanting when shoots growing on the short sections grow 3-4 true leaves; c, transplanting the stalks with the shoots in culture containers; d, placing pots of Alocasia macrorhiza, growing normally in the step c, at random, managing by a conventional garden technique, and keeping water and fertilizer supply. The culture medium is made with, by weight, 50-60% of common soil, 35-45% of leaf mold, and 5% of fine sand; 15-20g of compound fertilizer is added per 5kg of the culture medium.

Description

Technical field: [0001] The invention belongs to the field of ecological and environmental protection science and technology, and in particular relates to a method for quickly greening a roof with a large herb plant calla lily. Background technique: [0002] Greening is an important means to improve urban heat island effect, air pollution and other ills. As a new form of greening, roof greening not only saves urban greening land, improves urban landscape and urban ecological quality, but also improves the city's taste and competitiveness , creating good economic and social benefits. However, due to the limitation of roof load-bearing capacity and roof climate and other factors, the plants used in roof greening should not only be light in weight when planted, but also need luxuriant branches and leaves, strong resistance to stress, drought resistance, and less maintenance. At present, the plants used in the three-dimensional roof greening are mainly small herbaceous plants o...
