Embodiment 1

[0028] Embodiment 1: configure 1000 kg of light ecological nutrient soil for roof greening, and the planted crops are water spinach.

[0029] Weighing: biogas residue (residual biogas residue from Anyang Zhongdan Bioenergy Co., Ltd.), 135kg, furnace slag 85kg, loess 190kg, rice husk (Yellow Riverside Rice Processing Plant, Yuanyang, Henan Province) 300kg, mushroom residue 155kg, 130kg of pine needle soil, 5kg of earthworms (Daping No. 2).

[0030] Among them, the rice husk and mushroom dregs are mixed, and an appropriate amount of water is added, stacked and retting at 50°C for 30 days, defatted and fermented. Mix the fermented rice husk and mushroom slag with other dry raw materials, adjust the water content to about 50%, and then add live earthworms.

[0031] The above-mentioned light ecological nutrient soil for roof greening is filled in the bricked vegetable pond or antiseptic wood flower box on the roof, and the thickness of the pavement is 25cm, sowing water spinach se...

Embodiment 2

[0033] Embodiment 2: configure 1000 kg of light ecological nutrient soil for roof greening, and plant dwarf tall fescue lawns.

[0034] Weighing: biogas residue (residual biogas residue from Anyang Zhongdan Bioenergy Co., Ltd.) 125kg, slag 75kg, loess 175kg, rice husk 320kg, mushroom residue 150kg, pine needle soil 150kg, earthworms ( white stem ring hairworm) 5 kg. Among them, the rice husk and mushroom dregs are mixed and added with appropriate amount of water, stacked and retting at 45°C for 30 days, degreased and fermented. After mixing the fermented rice husk, mushroom dregs and other raw materials, it is ready.

[0035] Fill the well-mixed roof nutrient soil into the brick-built pond and the antiseptic wood flower box on the roof, 6cm, sow lawn seeds, suppress, and water. The seedlings will emerge after 10 days, and then water every 15 days, and the stubble will not exceed 6cm. After 32 days, the seedlings will be completely formed and dense. In Zhengzhou, the green pe...

Abstract

The invention relates to lightweight ecological nutrient soil for roof greening and a method for preparing the lightweight ecological nutrient soil. The nutrient soil is made of dry basis raw materials including 10-20% of biogas residues, 5-15% of slag, 10-20% of loess, 25-35% of rice hulls, 15-25% of mushroom residues and 15-30% of pine needle soil, and living earthworms accounting for 0.2-1% of the total mass of the dry basis raw materials. The nutrient soil is light in load, low in volume weight, free from hardening, resistant to trampling, fine in moisture and fertility preserving performance, pollution-free, extensive in source of raw materials, low in cost, simple in production process and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a lightweight ecological nutrient soil for roof greening and a preparation method thereof. Background technique [0002] With the increase of urban density and multi-layered buildings, urban greening develops into three-dimensional space, expands green space, and expands a form of greening and beautifying urban multi-dimensional natural factors. Roof greening mainly brings huge environmental benefits and economic benefits to cities in terms of alleviating the urban heat island effect, improving energy-saving benefits of buildings, reducing the load on urban rainwater treatment systems, improving urban landscapes, and enriching urban species diversity. However, what needs to be considered in roof greening is the load-bearing issue of the roof. Because it is not grounded, the water and fertilizer retention of the nutrient soil used must also be considered. Therefore, the nutr...
