Embodiment 1

[0021] Embodiment 1: hanging greening cultivation substrate

[0022] First crush the green plant waste to a particle size of less than 2cm, and then measure the concentrated sludge (water content <80%) or livestock and poultry manure produced by the urban domestic sewage plant that accounts for 15% by weight of the green plant waste, and then according to In the green plant waste, the number of branches or new leaves is different, and urea is added (if the branches, especially the dead branches, are 70-80% by weight of the green plant waste, add 0.8 per cubic meter of crushed green plant waste). kg of urea, if the content of young leaves is 70-80% by weight of the weight of greening plant waste, 0.5 kg of urea or not added to every cubic meter of crushed greening plant waste), to green plant waste and domestic sludge Or the mixed C / N of livestock and poultry manure etc. shall be 25-30.

[0023] Compost the uniformly mixed green plant waste (because the green plant waste has a...

Embodiment 2

[0026] Embodiment 2: potted cultivation substrate for greening

[0027] First crush the greening plant waste to a particle size of less than 2cm, measure 30% cow dung of the weight of the greening plant waste, add it, and then add about 0.5 kg of urea to the greening plant waste per cubic meter of crushed greening plant waste. The C / N of plant waste mixed with cow dung and urea is 25-30. Because the particle size of the green plant waste is relatively moderate, the height of the pile is about 0.6-1.5m. Turn over once after 3-4 days at high temperature, and pay attention to adding water appropriately to keep the humidity at 45-60%. It is decomposed in about 30 days, and after about 20 days of decomposing time, it is ensured that the germination index is above 80%. The physical and chemical properties are then detected, and the assay method is the same as in Example 1. The measurement results show that the EC is somewhat high, adding about 12% of perlite reduces the EC to 1.54...

Abstract

The invention relates to a preparation method of a cultivation substrate used for three-dimensional afforesting. The method comprises the steps of: first, crushing plant waste to particles of 2cm; then adding sewage sludge or animal manure in an amount of 5-30% by weight, based on the weight of the plant waste; mixing the plant waste and the animal manure and piling the mixture to be piles with a height of 0.60m-1.5m, and volume of no less than 2 cubic meters; compost maturing the mixture for 20-40 days to obtain a compost product with water content less than 38%; and according to the requirements of national forestry standard 'organic media for greening use', based on the weight of the compost product, adding 0-0.5% humic acid and/or 0-20% perlite, and/or 0-0.5% polyacrylamide to obtain the cultivation substrate which meets the cultivation substrate requirements in the national forestry standard 'organic media for greening use' (LY/T1970-2011) issued in 2011. The method promotes the recycling of waste, and the cultivation substrate has great social, economical and ecological benefits and can replace nature soil for planting. The cultivation substrate can especially satisfy the requirements of roof, suspension, verticality, etc. three-dimensional afforesting for soil fertility, soil composition and water retention and fertilizer conservation.

Description

technical field [0001] The invention relates to a method for preparing a cultivation substrate for three-dimensional greening, in particular to a method for preparing a cultivation substrate with greening plant waste. It belongs to the fields of urban landscaping, municipal management and agricultural technology. Background technique [0002] With the rapid development of urban greening, fertile topsoil resources in cities are becoming more and more scarce, so people use artificial cultivation soil instead of topsoil for urban greening. For example, the invention that we have successfully developed and obtained the patent right is "Method for preparing cultivation soil with sludge, branches and leaves and mineralized garbage", and the invention with the patent number 200610118501.5 is to use mineralized garbage, domestic sewage plant sewage The cultivation soil obtained by the reasonable ratio of mud and branches and fallen leaves compost products has a slightly acidic pH o...
