Abstract

The present invention relates to a garden greening technique of a building field. A stone and defecation forest heat island effect of a city is obvious in company with the acceleration of urbanization course. The requirement of greening roofs and terraces is strong in order to increase the area of green lands. The traditional greening technique seems to be not suitable due to requirements to the greening of roofs of a plurality of old buildings with small roof loading capacity in the city and the consideration of developers to economic cost. The present invention provides a roof greening technique with crassulaceae plant jade hanging clocks, which is used for solving the flooring greening problem of various types of roofs in the city. The technique comprises the steps of frame manufacture, planting, stem planting, leaf planting, etc. The present invention has the advantages of light weight, wide application range, low construction and maintenance cost, no damage to environment and beautiful appearance.

Description

A kind of roof greening method

Technical field

The present invention relates to the city roof greening method in afforestation field.

Background technology

Along with rapid development of economy, quickening of urbanization process, many high buildings and large mansions are rised sheer from level ground, the stone dung forest tropical island effect in city is more obvious, for increasing greenery area, to roof greening, the demand of balcony greening etc. is stronger, the application technology of roof greening mainly concentrates on the improvement of plantation matrix and the application of new type roof at present, and new wild greening resource plant is excavated and application facet rarely seen application that Crassulaceae plant stringy stonecrop is arranged.

But, the greening technique that these are traditional, for the greening on old-fashioned building roof quite a lot in the city, just seeming is not suitable for, because, the roof load ability of these buildings is little, for building newly-built in the city, real estate developer, regulation and the requirement of carrying out roof greening generally all arranged, the developer also needs roof afforestation technology in light weight, that cost is low for the consideration on the Financial cost, and these requirements are that present roof afforestation technology cann't be solved.

Summary of the invention

The purpose of this invention is to provide a kind of Crassulaceae plant kalimeris indica in light weight, with low cost and roof greening method thereof of building,,, improve environmental quality to increase city's green areas in order to solve the flooring greening problem on all types of roofs, city.

Roof greening method embodiment provided by the present invention comprises as follows:

The area that need afforest according to the roof, earlier make simple and easy framework with the thick fillet of about 2-3cm, intermediate section is divided into the square frame of long 40-50cm, be fixed on the flooring then, in framework, spread the thick peat soil of 15-20mm, sandy loam mixture grown layer as plant, the volume ratio of peat soil and sandy loam is 1: 1, then by the laxative remedy operation:

1), taking off the plantlet of taking root that kalimeris indica crawls on the stem implants in the planting soil;

2), during cuttage, the top stem that the long plumpness of clip 4-5cm is enriched inserts in the planting soil after the otch drying, can take root in about 7 days;

3), when leaf is inserted, cut single leaf, after otch dried, oblique cutting buried, insert and grew new root in back about 10 days, grew plantlet in about 30 days, watering kept ground moistening about 1 month, pruning that can be suitable or pinching after this, to control its height and to promote branch, in addition, need not other final-period management.

Principle: from the Physiological Ecology principle, this plant is a succulents, has powerful drought-enduring anti-lean anti-shallow soil capacity, the light-duty roof vegetation that is suitable for building thin soil layer; From Biological Principles, this plant plant is short, is easy to form the One's name is legion plantlet of taking root on crawl root and the stem, and stem, leaf also can be used as propagating materials, and propagating materials is abundant, and breeding is easy to form the planting quilt easily.

The advantage of this method:

1, in light weight, host material of selecting for use and planting material are all more less, and are to build the thin soil layer vegetation, thereby the roof vegetation weight that forms is very light, and the roof load that is increased is very little;

2, applied widely, in light weight because of formed roof, be applicable to all types of roof greenings;

3, construction and maintenance cost are cheap, and material therefor is obtained easily, low price, and selected stress resistance of plant and adaptive capacity are strong, need not final-period management substantially;

4, this technology compliance with environmental protection requirements, material therefor is natural biologic material, and environment has been protected on the greening roof, environment is not damaged;

5, good looking appearance, plant is short, only high 20-30cm, the close life of cauline leaf, the leaf look beautiful is changeable, when blooming, the inflorescence that booth is upright, an orange Xiao Hua in full bloom, tempting unusually, very attractive in appearance.

Roof greening method of the present invention is to produce because of demand that the human settlement improves, also is the effective measure of environmental protection, can estimate that market prospects are wide.The reasons are as follows:

There is old-fashioned building roof quite a lot in the city, and these roof load abilities are little, can't carry out the roof greening of conventional method, thereby in light weight, the novel roof afforestation technology easy, extensive management of constructing are had bigger demand.

New development of real estate generally all has regulation and the requirement of carrying out roof greening, during realtor's real estate newly developed, for the consideration of Financial cost, stronger demand is arranged in light weight, construction and maintenance cost is cheap, environmental protection is attractive in appearance novel roof greening method.

Method involved in the present invention is simple to operate, and material is easy to obtain, and is with low cost, can in the city dweller sub-district demonstration pilot project be set earlier, makes resident's physical experience, allows the user estimate, to use, and further introduces to the market.
