Provided by the present invention is the prescription of the light-duty roof greening planting matrix of main preparation with the obsolete material, has practical operability, the advance of the feature of environmental protection and invention.

Summary of the invention

The purpose of this invention is to provide a kind of is the novel roof greening matrix formulations of the green roof greening planting matrix in the main light-duty roof of preparation with the obsolete material.

The present invention realizes as follows:

1, matrix is formed main material:

Peat soil, wood sawdust, coconut palm chaff, perlite, haydite, yellow soil, durable composite fertilizer (slow-release fertilizer), water-loss reducer;

2, the preparation of matrix:

Material mixture ratio: peat soil 40-45%, yellow soil 18-20%, wood sawdust 10-15%, coconut palm chaff 8-10%, haydite 4-5%, perlite 3-4%, durable composite fertilizer (slow-release fertilizer) 0.81-1%, surplus are water-loss reducer.

3, principle:

1), porosity is big between haydite, is beneficial to ventilation, retaining, places the matrix bottom, is beneficial to absorption, utilization and the transfer of moisture; Perlite, water-loss reducer are mixed in the matrix in right amount, are beneficial to water conservation, retaining, can guarantee the water supply of plant;

2), the aeration status of soil directly influences the respiratory activity of root system of plant and microorganism, and in the soil solution various elements existence with utilize situation, the main composition material permeability of matrix formulations of the present invention is good, with an amount of common planting material reasonably combined after, be beneficial to very much plant to moisture, nutrient absorbing utilization, be beneficial to growth and development of plants;

The become thoroughly decomposed use of degree material of difference, and the application of durable composite fertilizer (slow-release fertilizer) have guaranteed that plant is to nutrient demand

The present invention compared with prior art has following advantage:

1), in light weight, the only about 450kg/m of unit weight ³(when doing) is to 920kg/m ³(wet time), light more about 50% to 100% than general afforesting matrix, can significantly alleviate roof load;

2), long service life, the material sustainable utilization time is long, difference the reasonably combined of degree material of becoming thoroughly decomposed, and the application of durable composite fertilizer (slow-release fertilizer), but the long period satisfy plant growing to nutrient demand;

3), environment-friendly function, obsolete material (wood sawdust, coconut palm chaff etc.) has directly been used in twice laid, has directly protected environment not contaminated, has purified environment;

4), be fit to most of tall careless plant growings of irritating, the become thoroughly decomposed reasonably combined use of materials such as degree and long-acting (slowly-releasing) fertilizer of different elasticities, difference, it is fixing and growth is required to satisfy most of tall thatched cottages top green plants of irritating;

5), applied widely, the light breed phytyl matter of being prepared not only is applicable to newly-built roof, more be applicable to the old-fashioned roof that weight bearing power is less, thereby its range of application is boundless;

6), reasonable price, material therefor or dead meal (as wood sawdust, coconut palm chaff), or common material (as yellow soil, peat soil), moderate, reasonable, easy to utilize.
