Embodiment 1

[0035] The invention discloses a simple mixed composting method of garden waste and waste vegetables, which comprises the following steps:

[0036] The first step, material mixing, choose fallen leaves as garden waste and crush them to a particle size of 3-10mm, and control their mass moisture content to 40.12%; choose vegetable leaves and vegetable stems as waste vegetables, crush and control their particle size to 2 ~8cm, mass moisture content 88.08%; according to the mass ratio of wet base of 9:1, add garden waste and waste vegetables and mix evenly, and then add yeast as EM composite bacteria according to the weight ratio of garden waste of 0.2%. Add urea at a ratio of 2% by weight of the garden waste to obtain a mixed compost material.

[0037] The second step is to ferment and compost. After the mixed compost material obtained in the first step is fermented at high temperature for 5 days, waste vegetables are added in a proportion of 5% by weight of garden waste, and 0.0...

Embodiment 2

[0039] The invention discloses a simple mixed composting method of garden waste and waste vegetables, which comprises the following steps:

[0040] The first step is to mix the materials. Use branches as garden waste and crush them to a particle size of 3-10mm, and control their mass moisture content to 20.21%; use vegetable leaves as waste vegetables, crush and control the particle size to 2-8cm, The mass moisture content is 94.91%; according to the wet base mass ratio of 17:3, add garden waste and waste vegetables and mix evenly, and then add 0.2% of garden waste or lactic acid bacteria as EM composite bacteria, according to garden waste Add urea at a ratio of 3% by weight of the material to obtain a mixed compost material.

[0041]The second step is to ferment and compost. After the mixed compost material obtained in the first step is fermented at high temperature for 7 days, waste vegetables are added in a proportion of 8% by weight of garden waste, and 0.1% by weight of g...

Embodiment 3

[0043] The invention discloses a simple mixed composting method of garden waste and waste vegetables, which comprises the following steps:

[0044] The first step is to mix the materials. Grass clippings are selected as garden waste and crushed to a particle size of 3-10mm, and the mass moisture content is controlled to 30.46%; vegetable stems are used as waste vegetables, crushed and the particle size is controlled to be 2-8cm , The mass moisture content is 87.47%; according to the mass ratio of wet base of 20:3, garden waste and waste vegetables are evenly mixed, and then yeast and lactic acid bacteria are added as EM composite bacteria according to the weight ratio of garden waste of 0.15%. Add urea at a ratio of 2% by weight of the garden waste to obtain a mixed compost material.

[0045] The second step is to ferment and compost. After the mixed compost material obtained in the first step is fermented at high temperature for 6 days, waste vegetables are added in a proport...

Abstract

The invention discloses a simple and easy garden waste and waste vegetable mixing composting method. The mixing composting method comprises the following steps: in the first step, mixing materials, adding garden waste and waste vegetables in the wet basis mass ratio of the garden waste to the waste vegetables being 9:1 to 17:3, then adding EM mixed bacteria according to the weight proportion of the garden waste being 0.1-0.2%, and adding urea according to the weight proportion of 1-3% of the garden waste, so as to obtain a mixed compost material; in the second step, performing fermentation composting, performing high temperature fermentation on the mixed compost material obtained in the first step for 5-7 days, then adding the waste vegetables according to the weight proportion of the garden waste being 5%-8%, adding the EM mixed bacteria according to the weight proportion of the garden waste being 0.05%-0.1%, and performing sufficient mixing and aerobic fermentation so as to obtain the compost. The composting method disclosed by the invention has the characteristics of being high in utilization rate of resources, simple in technology, low in cost, environmentally friendly and broad in purpose.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a simple mixed composting method of garden waste and waste vegetables. Background technique [0002] With the acceleration of the urban construction process, landscaping continues to develop rapidly, which in turn produces a large amount of garden waste. The traditional incineration and landfill treatment methods, on the one hand, produce incineration waste gas and landfill leachate, which pose a great threat to the environment. On the other hand, it also causes serious waste of resources. [0003] Composting can convert garden waste into organic fertilizer, which is of great significance to the development of organic fertilizer, improvement of soil fertility and promotion of sustainable agricultural development. Existing studies have shown that due to the characteristics of large wood fiber content, low moisture content, and large carbon-nitrogen ratio, garden was...
