Problems solved by technology

[0002] In the prior art, there are various soilless greening methods on the roof. One is to plant flowers and plants in a large area on the roof and use a groove bed, that is, to build a shallow groove with bricks, wooden squares or hard plastic frames. Soil substrate is laid in the groove, this kind of seedbed is difficult to set up, and the performance of moisture and fertilizer conservation is poor, which is not conducive to plant growth
In addition, the substrate thickness of the above-mentioned method is generally more than 10 cm. If an organic substrate is used, the effect of fixing the plant root system is extremely unsatisfactory due to its light weight and poor buildability, and plant lodging is prone to occur; if gravel, ceramsite, etc. are used Inorganic matrix, because of its heavy weight, it cannot be tolerated by ordinary roofs
The soilless cultivation method disclosed in the CN87102987A patent application document needs special flower fertilizer, flower cultivation and management are all relatively loaded down with trivial details, and it is not suitable for the soilless greening on the roof

Embodiment 1

[0015] Use an area of ​​1m 2 , thickness is 40cm block polystyrene foam board with concave hole as carrier, with sawdust and flower fertilizer as organic matrix, is that the sand grain of 31% is made inorganic matrix with porosity, by the weight ratio of sand: sawdust: flower fertilizer is 70 : 25:5 ratio to fully mix the three into a mixed carrier, fill it into the concave hole of the carrier, spread lawn turf on the surface of the mixed carrier, spray a small amount of water, and the lawn turf will turn green after a week, and its seedlings will grow luxuriantly. Assemble several green boards.

Embodiment 2

[0017] Use an area of ​​1m 2 , a block-shaped polystyrene foam board with grooves with a thickness of 85 cm is used as a carrier, bran, rotten leaves and flower fertilizer are used as an organic substrate, and ceramic particles with a porosity of 78% are used as an inorganic substrate, according to ceramic particles: bran : The weight ratio of rotten leaves: flower fertilizer is 94: 2: 3: 1. The four are fully mixed into a mixed carrier, which is filled in the groove of the carrier, and the seeds of "Clivia" are sprinkled on the surface of the mixed carrier. Spread a thin layer of organic substrate, spray a small amount of water, and water once every 3 days. The radicle will emerge after 12 days in an environment of 25-30°C, and the coleoptile will grow after 30 days. Pots.

Embodiment 3

[0019] Use an area of ​​1m 2 , a block-shaped polystyrene foam board with concave holes with a thickness of 60 cm is used as a carrier, sawdust and rotten straw are used as an organic substrate, and ceramic particles with a porosity of 83% are used as an inorganic substrate. The weight ratio is 80:15:5, the three are fully mixed into a mixed carrier, filled into the concave holes of the carrier, and the lawn turf is planted on the surface of the mixed carrier, sprayed with a small amount of water, and the lawn turf turns green after a week. The seedlings grow lushly, and several green boards are put together.

Abstract

This invnetion discloses a method to make green on roof of buildings without soil. It is realized by using blocks of polystyrene foam plate as corrier, using sawdust, bran, plant humus of fertilizer as organic base manure to provide nutriment for plants, using and pottery and porcelain or grit as inorganic base medium to make root system of plant fixed. The weight ratio between inorgamic medium and organic medium is 70-95:5-30. This method has solved the problems about poor performance of keeping moisture and maintaining the manure and high cost when make green on existing building roof. This invention has advantages as following: good technical effect, convenient to use, easy to implement, without pollution and soil disease, so, it can be widely applied to virescence to the building roof without soil.

Description

technical field [0001] The invention relates to a soilless greening method on the roof of a building. Background technique [0002] In the prior art, there are various soilless greening methods on the roof. One is to plant flowers and plants in a large area on the roof and use a groove bed, that is, to build a shallow groove with bricks, wooden squares or hard plastic frames. Paving with soil matrix in the groove, this kind of seedbed is difficult to set up, and the performance of moisture and fertilizer conservation is poor, which is not conducive to plant growth. In addition, the substrate thickness of the above-mentioned method is generally more than 10 cm. If an organic substrate is used, the effect of fixing the plant root system is extremely unsatisfactory due to its light weight and poor buildability, and plant lodging is prone to occur; if gravel, ceramsite, etc. are used Inorganic matrix, because of its heavy weight, cannot be supported by ordinary roofs. The soil...
