(Chinese invention patent application number: 02111227.4) invented a kind of sedum lineare roof greening seedling block that is used for roof greening such as Zhao Dingguo, carry out the cultivation of stringy stonecrop seedling piece on ground, when stringy stonecrop up to 3 centimetres, cover degree reaches 90% when above, be divided into a certain size finished product seedling piece, finished product seedling piece monoblock is carried to the roof, monoblock directly full shop splicing, a shop can become the level ground, makes roof greening more easy.Though stringy stonecrop with its superpower drought-enduring performance as the main selection in the present Green Roof Plants, but also having, it can not trample the two big defectives relatively poor with landscape effect, secondly, linear stonecrop for roof greening can not have any economic benefit, can't solve the bottleneck problem of the insufficient funds that present city roof greening suffers from applying.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, a kind of roof lawn used as putting green of golf is provided, the high-quality lawn greening of view grace can not only be provided, also have amusement, body-building function concurrently, can be used as the place that the city crowd carries out the high-grade leisure amusement and carries out golf body building, its business income can also solve the construction and the maintenance fund of roof greening fully.

In order to realize such purpose, the present invention directly lays on roofing by two-layer building fleece and the watertight composition that places flexible plastic film therebetween to form, on watertight composition, lay the drainage blanket of forming by gravel, utilize the inclination and the space between gravel particle of roofing nature to carry out draining, laying nonwoven on drainage blanket moves down to prevent soil particle as filter course, lay the level ground bed soil matrix layer that effluent is husky and fertilizer is mixed and forms above the filter course, the plantation evergreen bent grass green turf of crawling of the four seasons on the bed soil matrix layer of level ground.

The roof lawn used as putting green of golf of the present invention's design comprises watertight composition, drainage blanket, filter course, level ground bed soil matrix layer and the bent grass green turf of crawling, at first, directly on the roof, plane that the slope of inclining is arranged slightly, lay one deck watertight composition, watertight composition is by two-layer soft shockproof building fleece and place flexible plastic film therebetween to form a confined layer, the plastic foil watertightness is good, have waterproof infiltration and prevent the ability that root system penetrates, and can anti-pitch etc. the chemical attack of construction material.On watertight composition, be that gravel about 5mm is laid to the thick drainage blanket of 5cm with particle diameter, on drainage blanket, lay the nonwoven of two-layer porous gas as filter course, on the nonwoven filter course, re-lay the thick level ground bed soil matrix layer of 15-20cm, level ground bed soil matrix effluent sand and fertilizer are mixed and form, to guarantee the demand of the required water of green turf healthy growth, gas, nutrition.The bent grass green turf of crawling that the four seasons are evergreen is then directly sodded and is grown on the bed soil matrix layer of level ground.

Roof lawn used as putting green of golf of the present invention is simple in structure, realize easily, green turf the best in quality can not only be realized the city roof greening, beautify, can provide people to carry out the graceful golf body building and the place of amusement and recreation again, solve the bottleneck problem that roof greening construction and managed fund lack simultaneously.
