There are about 18,000 tons of waste generated by greening maintenance every year, including 14,500 tons of pruned branches and 350 tons of litter. At present, there are three main ways to deal with these green wastes: landfill, incineration and resource treatment. Incineration has been eliminated due to serious air pollution. Prohibition, landfill, occupying a large amount of land resources, easy to pollute groundwater and produce carbon dioxide and hydrogen sulfide and other disadvantages, so it is more and more urgent to explore green waste resource treatment

Embodiment 1
[0019] A preparation method of ecological organic fertilizer, comprising the following steps:
[0020] Step 1) pulverize the collected greening waste into lignocellulosic raw materials with a diameter no more than 5 mm in thickness;
[0021] Step 2) Fermenting the raw materials in a fermentation tank with a temperature of 0°C-15°C for about 40 days;
[0022] Step 3) sending the fermented raw materials into the sun room for decomposing and aging, and performing a second temperature rise;
[0023] Step 4) overturning the raw material once every 10 days, a total of three overturning;
[0024] Step 5) After the raw materials are decomposed and aged for 60-70 days, they are subjected to ecological treatment such as thickness screening, without adding any chemical products, so as to obtain qualified ecological organic fertilizers.

Abstract
The invention discloses a preparation method of an ecological organic fertilizer. The preparation method comprises the following steps: (1) grinding collected greening wastes into wood fiber raw materials with a diameter not larger than 5 millimeters; (2) placing the raw materials in a fermentation tank to carry out fermentation for 30 to 40 days; (3) delivering the fermented raw materials to a sunshine room to carry out aging, and carrying out secondary heating; (4) turning over the raw material for every 10 days, and repeating the turning treatment for three times; (5) screening the raw materials according to the particle size after 60 to 70 days of aging, and finally carrying out an ecological treatment without any chemical product so as to obtain the qualified ecological fertilizer. After the high-temperature aging treatment, the fertilizer does not contain any weed seed, insect egg or harmful chemical component, and moreover the fertilizer can improve the fertilizing performance and water-retaining performance of the soil, improves the growth situation of plants, increases the content of beneficial microorganisms in the soil, assists the plant root growth and nutrition absorption, and strengthens the disease resistant performance of the plants.
Description
technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for preparing ecological organic fertilizers. Background technique [0002] Kunshan Development Zone has 15 parks with an area of 2.7 million square meters, and street green space of 11.5 million square meters. There are 18,386 street trees in the area: camphor, sycamore, and magnolia account for 83.6% of the total street trees, and other tree species account for 16.4%. There are about 18,000 tons of waste generated by greening maintenance every year, including 14,500 tons of pruned branches and 350 tons of litter. At present, there are three main ways to deal with these green wastes: landfill, incineration and resource treatment. Incineration has been eliminated due to serious air pollution. Explicit prohibition, landfill, occupying a large amount of land resources, easy to pollute groundwater and produce carbon dioxide and hydrogen sulfide and other disadvantages, ...
