Abstract

A method for planting green grass on roof surface for insulating and afforesting the roof and preventing its leakage includes naturalizing the grass seeds of Crassulaceae on ground, antileakage treating of roof, checking the roof surface with wood bars, spreading the grass seedlings in checks, irrigation and applying composite organic fertilizer. Its advantages include high drought resistance and high heat-insulating, anti-leakage and afforesting effect.

Description

The cultivation method of green grass on roof

The present invention relates to a kind of at the cultivation method of building green grass on the roof.

Along with increasing sharply of urban population, therefore the air pollution in the city is serious, and environment is abominable, and the storied building top surface of people's inhabitation at present is plane formula basically, generally be after having done anti-drain process, add thermal insulation layer again, the roof of this form is under the irradiation of burning sun in summer, and the top layer indoor temperature exceeds the several years than the indoor temperature of lower floor, the roof of this form is through exposing to the sun and rain in addition, watertight composition is easy to wear out, and the garret drainage is brought very big inconvenience up to more than 85% to resident family.The disclosed cultivation method of Chinese invention patent " cultivation method of green grass on roof " (application number 99115543.2, August 30 1999 day for announcing, notification number CN1244336A), its major defect is: 1. since its use be inorganic fertilizer (as urea, composite fertilizer etc.), its fertilizer efficiency time is short, the frequent yellowing of grass seedling needs repeatedly to mend fertilising.Be difficult to the control amount of executing at high temperature season, often cause the death of careless seedling monoblock.The long-term use of inorganic fertilizer certainly will cause the pollution to environment; 2. use hormones such as growth hormone easily to cause careless seedling bottom rot, influence attractive in appearance; 3. adopt neither convenient construction of cement moulding, cost is high again.

The object of the present invention is to provide a kind ofly neither environment to be polluted, be easy to again safeguard and the cultivation method of green grass on roof simply and easily.

The objective of the invention is to realize by following approach: a kind of cultivation method of green grass on roof is to take the following step to cultivate:

1. press 100g/m ²Ratio toward wood sawdust or be cut into to add in the long straw or like vegetable of 1-3cm and be diluted to 8% copper-bath and ferment, disinfect;

2. deck is carried out leakproof and detect processing;

3. on the good flat roof of detection, carry out the lattice location, and on the batten moulding, leave apopore with batten;

4. wood sawdust or straw or like vegetable after will fermenting are pressed 3-5Kg/m ²Ratio add compoiste fertilizer and admix, and evenly be layered in the batten moulding bedding, thickness is 2-4cm;

5. the greenstone grass (stringy stonecrop) after will taming saves naturally according to it and is cut into the 1-8 joint, and presses 0.25-2Kg/m ²Density be tiled on the bedding, water until drenched, press 4-8Kg/m then ²Ratio on seedling, impose compoiste fertilizer equably, and make it in vegetative period, keep moistening;

6. greenstone grass (stringy stonecrop) beginning rudiment after 6-8 days treats that it grows up to 8-10cm and sprays an insecticide when high.

Described compoiste fertilizer be with volcanic mud, ight soil, superphosphate, Ammonium bicarbonate food grade by the ratio of weight and number mixed preparing after fermentation of 60-85: 10-25: 3-5: 1-2 10-15 days, add in the ratio of fermentation back compoiste fertilizer weight 5% again and be diluted to 8 ‰ copper-bath and make.

The Crassulaceae greenstone grass (stringy stonecrop) that the present invention plants is nodular, each joint can both land and take root, gives birth to branch, and have good characteristics of drought-enduring performance, temperature-15 ℃ to 80 ℃ it can be dead, in the survival period on the cement roof more than 8 years, have very strong vitality, need any management behind the garden of covering with into hardly.The cultivation method of green grass on roof of the present invention adopts compoiste fertilizer, has fundamentally changed the pollution of using inorganic fertilizer to bring to environment, and it can offer the vegetation prescribing adequate nutrition simultaneously, and need not frequent nursing; Adopt batten to make framework, saved the complicated procedures of forming when water is clay to be done, and can repeatedly use repeatedly, easy accessibility greatly reduces cost, has improved efficient; Greenstone grass (stringy stonecrop) transplanting can be become the thick green layer in one deck 30cm left and right sides behind the roof; can reduce indoor temperature 2-5 ℃; simultaneously can also protect expanding with heat and contract with cold of roof waterproof layer, thereby prolong the ageing time of watertight composition, this grass growth back vegetation coverage reaches more than 95%.

Below the present invention is described in further detail:

Embodiment: the cultivation method of green grass on roof of the present invention is: at first press 100g/m ²Ratio toward wood sawdust or be cut into to add in the long straw or like vegetable of 3cm and be diluted to 8% copper-bath and ferment, disinfect; Deck is carried out antiseep detect to handle, the 8cm that can earlier roofing be soaked is dark or roofing ceaselessly sprayed water 8 hours, and observing the roof has the ne-leakage phenomenon, must take waterproof measure till non-leakage if any seepage, can carry out transplanting work; Batten with 2 * 5cm on the good flat roof of detection carries out the lattice location, according to the current direction of roofing, leaves several 0.5cm on the batten moulding ²Apopore, stop up sewer to prevent wood sawdust or straw or like vegetable or earth; Wood sawdust or straw or like vegetable after the fermentation are pressed 4Kg/m ²Ratio add compoiste fertilizer and admix, and evenly be layered in the batten moulding bedding, thickness is 3cm, described compoiste fertilizer be with volcanic mud, ight soil, superphosphate, Ammonium bicarbonate food grade by 80: 15: 3: 2 weight fraction is than mixed preparing after fermentation 12 days, adds in the ratio of fermentation back compoiste fertilizer weight 5% to be diluted to 8 ‰ copper-bath and to make again; Greenstone grass (stringy stonecrop) after will taming again saves naturally according to it and is cut into 2 joints, and presses 1Kg/m ²Density be tiled on the bedding, water until drenched, press 6Kg/m then ²Ratio on seedling, impose compoiste fertilizer equably, and keep it moistening in vegetative period; After greenstone grass (stringy stonecrop) the beginning rudiment, treat that it grows up to 8cm and sprays the insecticide of a diluted concentration when high.

Claims

1. the cultivation method of a green grass on roof is characterized in that taking the following step to cultivate:

2. deck is carried out leakproof and detect processing;

2. the cultivation method of green grass on roof as claimed in claim 1, it is characterized in that described compoiste fertilizer be with volcanic mud, ight soil, superphosphate, Ammonium bicarbonate food grade by the ratio of weight and number mixed preparing after fermentation of 60-85: 10-25: 3-5: 1-2 10-15 days, add in the ratio of fermentation back compoiste fertilizer weight 5% again and be diluted to 8 ‰ copper-bath and make.
