Problems solved by technology

However, this patent has the following disadvantages: 1. The main component of the patent matrix is ​​peat, and the price of peat is higher than that of waste materials. If it is put into production, the cost will increase
2. Among them, perlite and ceramsite are commonly used matrix components in gardening, and the price is higher than that of industrial and agricultural waste materials, which further increases the cost of this matrix
3. The sawdust and coconut peat used in this patent do not belong to mass waste. The scope and area of ​​such waste are limited, the quantity is relatively limited, the purchase and transportation costs are high, and the supply may be insufficient in the production chain, so it is n

Embodiment 1

[0027] Embodiment 1: the preparation of roof greening cultivation substrate

[0028]First, the landscaping waste is crushed into particles with an average particle size of 1-10mm with a pulverizer, and the basic physical and chemical properties such as pH, carbon-nitrogen mass ratio and water content of the landscaping waste and municipal domestic sludge are tested and analyzed respectively, and the landscaping waste Waste (12kg) and municipal domestic sludge (10kg) were mixed evenly, and the moisture content was adjusted to 61%, and the carbon-to-nitrogen mass ratio was 25, and forced ventilation aerobic composting was carried out;

[0029] Carry out aerobic composting in the aerobic composting reactor, the heap body is 80L (increasing heat preservation measures in winter), forced interval ventilation oxygen supply, control ventilation rate 250L / H, ventilation mode is to pass 10 minutes, stop 50 minutes, with this as One cycle, continuous circulation and ventilation for 30 da...

Embodiment 2

[0032] Embodiment 2: the comparative experiment of roof greening cultivation substrate

[0033] The roof greening cultivation substrate prepared in Example 1 and peat, garden soil (grinding through 2mm sieve hole) perlite, coal cinder, plant ash are combined to form 9 kinds of planting substrates, and the substrates are mixed by volume. The specific ratio is as follows:

[0034] Table 1 Comparison test of different planting substrates

[0035]

[0036]

[0037] Put 9 kinds of substrates in 50×50cm planting boxes respectively, each planting substrate has a thickness of 7cm, and each planting box is planted with 7cm-cut S. Line, a total of 215 species. Water once a day around 2:30 p.m., the amount of water is the amount of water evaporated the day before (weigh the total weight of the planting box before each watering), and the planting time is 37 days.

[0038] The results of the planting experiment showed that the physical indicators of compost:perlite=5:1 were superi...

Abstract

The invention provides a roof greening culture substrate which is prepared from landscaping waste, city living sludge and perlite. A preparation method of the roof greening culture substrate comprises the following steps: (1) firstly uniformly mixing the grinded landscaping waste and city living sludge to obtain a mixture, adjusting the water content of the mixture to be 55-65% and adjusting the mass ratio of carbon to nitrogen to be 25-30, carrying out forcible ventilation to for aerobic composting at a temperature of 50-60 DEG C, thus obtaining a composting product after the composting process; and (2) uniformly mixing the composting product and the perlite according to a volume ratio of (5-15): 1 to obtain the roof greening culture substrate. The common landscaping waste and city living sludge are applied to the roof greening culture substrate, thus being contributed to reducing the material cost of the roof greening culture substrate, improving the comprehensive utilization level of the natural resources, promoting the cyclic utilization of the landscaping waste and protecting the natural environment.

Description

(1) Technical field [0001] The invention relates to a roof greening cultivation substrate and a preparation method thereof, in particular to a roof greening cultivation substrate material prepared mainly by using landscaping waste and urban domestic sludge as compost materials and supplemented with perlite. (2) Background technology [0002] With the continuous expansion of the city area, a large amount of land is used to build high-rise buildings and modern factories. The urban heat island effect and air quality are increasingly affected by people's lives. Greening the city is becoming more and more important. Among them, the roof Greening is one of the forms of greening. Since the current roof greening substrates use pure soil, peat, perlite, sand, etc. as cultivation substrates, each substrate has its own disadvantages, such as high density of soil and sand, and the limited load-bearing of old roofs, which poses safety hazards. In addition, these inorganic The water and ...
