Preparation method of ecological organic fertilizer

Abstract

The invention discloses a preparation method of an ecological organic fertilizer. The preparation method comprises the steps of 1) crushing collected greening garbage into a wood fiber raw material ofwhich the diameter does not exceed 5mm; 2) fermenting the raw material in a fermentation tank for 30 to 40 days; 3) feeding the fermented raw material into a sunlight room for decomposing and aging,and carrying out secondary heating; 4) turning over the raw material once every 10 days, wherein the raw material is turned over for three times in total; and 5) decomposing and aging the raw materialfor 60 to 70 days and then carrying out ecological treatment such as fineness screening, and meanwhile, without any chemical product, acquiring the qualified ecological organic fertilizer. The organic fertilizer product does not contain weed seeds and worm eggs after high-temperature decomposition, harmful chemical components are not added, the soil fertility and the drought resistance and waterretention capacity can be improved, the plant growth condition can be improved, the content of beneficial microorganisms in soil is increased, plant root growth and nutrient absorption are facilitated, and the disease resistance of botany is improved.

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, ...

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
