Abstract

The soilless culture technology of planting grass in roof includes setting cement strips around roof, separating the part in the strip frame, spreading base fertilizer, planting grass, and watering. The present invention has the advantages of increasing green land, improving city air quality, protecting waterproof layer structure of roof to prevent water seepage and low cost, etc.

Description

Soil-less grass planting technology for greening roof

Technical field.

The present invention relates to a kind of grass on roof cultivation technique without soil.

Background technology.

At present, because urbanization is growing, the soil in city has been an inch of land is an inch of gold, and a large amount of soils is used to build commercial office complex and residential building, and vacant lot is also just fewer and feweri, greenery area is also fewer and feweri, people live the city for a long time, feel that generally urban air-quality is poor, suffer from the also more and more of respiratory disease, raising day by day along with people's level of production, requiring increases city's green areas, and the cry that improves urban air-quality is also more and more stronger, makes afforestation square but will take out a lot of soils in the city, also be very difficult, and be desert a slice on the roof of urban building, so not only the waterproof construction on roof is directly exposed to the sun and rain, and is aging easily, leak, and live the resident family of top layer, at temperature height in summer, and in winter, temperature is very low, all is reluctant to stay in top layer.

Summary of the invention.

The object of the present invention is to provide a kind of at soil-less grass planting technology for greening roof.

The objective of the invention is to realize by following approach:

1): around deck, use the cement mortar panel, on panel, be provided with discharge outlet, filter screen is housed in the draining;

2): carry out the lattice location with cement bar or water-fast corrosion resistant ornamental strip in panel, each lattice area is at 5-15M ²

3): with the sawdust sieve aperture is after the 4-8 millimeter sieves with interior screen cloth, to mix 3%-5% fused calcium magnesium phosphate and 5%-10% farmyard manure, makes base manure after the uniform mixing, is layered in the lattice, and thickness is lower than dividing strip;

4): grass planting: the rhizome portion that will be suitable for the Crassulaceae grass seedling of cuttage inserts in the base manure;

5): water: adopt vaporific spraying, be sprinkled upon equably on the seedbed, keep the seedbed moistening.

The present invention has following advantage:

1: can increase city's green areas greatly, improve urban air-quality;

2: can protect the structure of building roof membrane, prolong the service life of watertight composition, the generation of avoiding leaking;

3: increased leisure, the stroll of city inhabitant, the place of motion;

4: the present invention has also that construction costs is low, and maintenance workload is few, easily the characteristics of promoting.

The specific embodiment.

1): around deck, use the cement mortar panel, be provided with discharge outlet at panel, row Filter screen is housed on the mouth of a river;

2): carry out the lattice location with the cement bar in panel, each lattice area is at 10M²；

3): be after 6 millimeters screen cloth sieves, to mix 3% calcium magnesium phosphate with the sawdust sieve aperture With 8% farmyard manure, make base manure after the uniform mixing, be layered in the lattice, thickness is lower than dividing strip;

4): grass planting: the rhizome section that will be suitable for the Crassulaceae sedum lineare grass seedling of cuttage inserts base manure In; A section header is landed;

5): water: adopt vaporific spraying, when spray was watered, nozzle should not directly face toward seedling, Answer nozzle up, allow the water smoke that is vaporific naturally waft down, be sprinkled upon equably on the seedbed, keep The seedbed is moistening, does not produce current.

Claims (1)
