Abstract
The present invention relates to a kind of entitled green plain roof greening light ground mass of treasured, the light ground mass using volume ratio be 85~90% lightweight silicate granules, 10~15% zeolites as base-material, sterilization processing is expanded through high temperature and high pressure steam after uniform mixing, then sprays addition nutrient solution and is mixed.The characteristics such as the present invention has from heavy and light, not hardened, water conservation, fertilizer conservation, good permeability, it is effectively reduced roof load, prevent from forming mud, solve the problem of matrix is lost in, add nutrient solution, the nutrients, high temperature and high pressure steam processing base-material such as N, P, K needed for plant growth can be met it is possible to prevente effectively from growth insect pest, weeds and germ etc. cause secondary pollution to influence roofing environment.
Description
Technical field
The present invention relates to garden afforestation technology field, and in particular to a kind of entitled green light-duty base of plain roof greening of treasured
Matter.
Background technology
With the quickening of urbanization process, high-rise, high-rise building is more and more, for the city's looks that improve the appearance of the city, saves greening
Land used, roof greening is progressively come among the life of people, and on the one hand roof greening can play the purpose beautified the environment, another
Aspect can also play retaining effect, mitigate the pressure of municipal drainage system, but roof greening has very high technical requirements, by
The limitation of the factors such as roof weight capacity, roof natural conditions (including illumination, moisture, wind-force etc.), the matrix of roof greening
Must possess the characteristics such as lightweight, water-holding capacity be strong, traditional roof greening substantially indiscriminately imitates ground afforestation mode to room
Top, its adaptability is influenceed by factors such as roof load-bearing, has a strong impact on the popularization of roof greening, therefore lightness roof greening turns into
The focus of current research, lightness roof greening is mainly reflected in the use of plant cultivation media, to mitigate roof as far as possible
Bearing capacity, this just proposes higher requirement to cultivation of plants matrix.
The content of the invention
It is an object of the invention to provide a kind of entitled green plain roof greening light ground mass of treasured, to solve existing room
The problems such as top greening weight weight, poor water retention property.
To achieve the above object, the inventive method is using lightweight silicate granules, zeolite as base-material, through high temperature after uniform mixing
High steam sterilization processing, adds nutrient solution and is mixed.Specifically, this method comprises the following steps：
A kind of green plain roof greening light ground mass of entitled treasured, by 85~90% lightweight silicate granules of volume ratio,
10~15% zeolites are base-material, expand sterilization processing through high temperature and high pressure steam after uniform mixing, then spray addition nutrient solution mixing
Form；
Further, the addition of the nutrient solution is calculated as with the volume of base-material：500~1000g/m of potassium dihydrogen phosphate3、
200~1000g/m of diammonium hydrogen phosphate3, 300~1000g/m of urea3, it is added to the water fully dissolving mixing；
Further, the pressure of the high temperature and high pressure steam is 0.1~0.2MPa, and temperature is 110~150 DEG C；
Further, the physical and chemical index of the light ground mass is：260~360kg/m3 of saturation water unit weight, thermal conductivity factor
0.055~0.06W/MK, water holding water 120~150%, 100~150kg/hm of permeability2, it is pH 6.5~7.5, inorganic
Thing content 95~98%；
Further, the particle diameter of the silicate granules is 0.5~3mm；
Further, the light ground mass also includes slow-release carbamide, and addition is 1000~2500g/m3。
The inventive method has the following advantages that：
1st, the present invention using silicate granules, zeolite as base-material, with from heavy and light, not hardened, water conservation, fertilizer conservation, good permeability
Etc. characteristic, roof load is effectively reduced, prevents from forming mud, the problem of matrix is lost in is solved, nutrient solution is added, meets and plants
The nutrients such as N, P, K needed for thing growth.
2nd, base-material is carried out steam high temperature high pressure process by the present invention, and the germ mixed in base-material, weeds seed, worm's ovum etc. are killed
Extremely, it is to avoid growth insect pest, weeds and germ etc. cause secondary effect to roofing environment.
3rd, slow-release fertilizer is added in the present invention, can effectively meets demand of the plant growth different phase to nutriment, together
When zeolite there is certain cation exchange capacity (CEC), fertilizer conservation Water-saving effect is good, can effectively control the fast-growth of plant.
