[0046] The storage and drainage board for greening has the characteristics of light weight, easy instal...

Embodiment 2

[0069] Drainage layer: storage and drainage board for greening;

[0070] Nutrient layer medium: 45% perlite, 40% sawdust, 10% medical stone, 5% pumice (the above are volume percentages);

[0071] Addition amount of nutrient layer fertilizer: nitrification inhibitor 8g / m 3 , Potassium sulfate for agricultural use 150g / m 3 , diammonium hydrogen phosphate 100 / g m 3 , urea 200g / m 3 , Agricultural copper sulfate 10g / m 3 , manganese sulfate 15 g / m 3 , agricultural zinc sulfate 10g / m 3 , Agricultural ferrous sulfate 10g / m 3 , boric acid 5g / m 3 , microbial pesticide 0.19g / m 3 , plant water retaining agent 200g / m 3 (The above are the weight of chemical reagents).

[0072] After mixing the above items separately, first lay a drainage layer of 5cm, and then lay a nutrient layer of 20-30cm; since tall fescue lawns are planted, there is no need to lay a mulch layer.

[0073] Planting plant varieties: green peach, cherry, purple leaf dwarf cherry, pomegranate, hibiscus, Sophora j...

Embodiment 3

[0087] Drainage layer: storage and drainage board for greening;

[0088] Nutrient layer medium: 50% perlite, 35% sawdust, 13% medical stone, 2% pumice (the above are volume percentages);

[0089] Addition amount of nutrient layer fertilizer: nitrification inhibitor 15g / m 3 , Potassium sulfate for agricultural use 230g / m 3 , diammonium hydrogen phosphate 300g / m 3 , Urea 350g / m 3 , Agricultural copper sulfate 25g / m 3 , manganese sulfate 35g / m 3 , Agricultural zinc sulfate 25g / m 3 , Agricultural ferrous sulfate 25g / m 3 , boric acid 12g / m 3 , microbial pesticide 0.25g / m 3 , plant water retaining agent 250g / m 3 (The above are the weight of chemical reagents).

[0090] Covering layer: 70% medical stone + 30% pumice (the above are volume percentages);

[0091] After mixing the above items separately, first lay a drainage layer of 5cm, and then lay a nutrient layer of 20-40cm. Where the lawn is not laid, then lay a covering layer of 1-2cm.

Abstract

The invention relates to a multifunctional light inorganic culturing substrate for greening. The multifunctional light inorganic culturing substrate mainly comprises the following components in percentage by volume: 45-55 percent of pearl stone, 30-40 percent of thoroughly-decomposed wood dust, 8-13 percent of medical stone and 2-7 percent of pumice serving as media; meanwhile, a nutritional layer consisting of 8-20 g / m<3> of inorganic fertilizer nitrification inhibitor, 150-280 g / m<3> of agricultural potassium sulfate, 100-400 g / m<3> of diammonium phosphate, 200-500 g / m<3> of urea, 10-30 g / m<3> of agricultural copper sulfate, 15-40 g / m<3> of manganese sulfate, 10-30 g / m<3> of agricultural zinc sulfate, 10-30 g / m<3> of agricultural ferrous sulfate, 5-15 g / m<3> of boric acid, 200-300 g / m<3> of plant water retention agent and 0.19-0.38 g / m<3> of microbial insecticide is added; and a draining layer consists of water accumulating and draining plates for greening. The multifunctional light inorganic culturing substrate has the excellent properties of high particle strength, stable performance, durability, light weight, cleanliness, multiple functions, complete drainage, water retention, fertilizer retention, environmental friendliness, high efficiency, easiness and convenience for constructing, suitability for plant growth, and the like. The multifunctional light inorganic culturing substrate with a special agglomerate porous structure is better suitable for root system development of plants, and has a good fixing effect.

Description

technical field [0001] The invention relates to a cultivation substrate for greening engineering, which is especially suitable for building greening such as roof greening, sunny four-season hall, ecological road and bridge, etc., and can also be used for container seedling cultivation, square container flower beautification, potted flowers in homes and offices, saline-alkali land improvement, large tree Multifunctional inorganic cultivation light substrate for greening in transplanting and other projects. Background technique [0002] In recent years, roof greening has become one of the important measures of urban greening. Compared with roof gardens, light green roofs have the advantages of low cost, fast greening effect, and easy maintenance, and the promotion speed and construction area are increasing year by year. Not long ago, at the three-dimensional greening energy-saving and low-carbon seminar held in Shanghai, the participating experts analyzed and introduced mater...
