specific Embodiment approach 1

[0030] Specific implementation mode one: this implementation mode adds humic acid precursor material step by step and improves humic acid content method in compost, comprises the following steps:

[0031] 1. Compost protein organic waste and fibrous organic waste, and add MnO during the compost heating period 2 , the addition ratio is controlled at 0.01%-0.05% of the compost mass, and low-concentration polyphenol waste is added, and the addition ratio is controlled at 1%-5% of the compost mass;

[0032] 2. Before the high temperature period of composting, add sugar-containing waste, polyphenol waste and carboxyl waste to the compost of protein organic waste every time it is composted; Protein organic waste and carboxyl waste;

[0033] 3. In the high temperature period of composting, put the waste containing humic acid precursors into textile bags and bury them in the compost in the high temperature period of composting. ; The waste containing humic acid precursors is sugar-c...

specific Embodiment approach 2

[0035] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the proteinaceous organic waste includes livestock and poultry manure, catering waste or kitchen waste. material. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0036] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 1, the fibrous organic waste includes crop residues, straws, or forest residues, leaves, and weeds. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a composting method used for increasing humic acid content through phased adding of humic acid precusor substances. The composting method is used for solving a problem in the prior art that humic acid content is not high. The composting method comprises following steps: 1, protein organic waste and fiber organic waste are subjected to composting, at composting temperature increasing period, MnO2 is added, and a low concentration polyphenol waste is added; 2, before composting high temperature period, in each time of overturning of the protein organic waste, a sugar containing waste, a polyphenol waste, and a carboxyl waste are added, in each time of overturning of the fiber organic waste, the protein organic waste and the carboxyl waste are added; 3, at composting high temperature period, a humic acid containing precursor waste is packaged with textile bags, and is embedded in high temperature period compost; and 4, at composting temperature reduction period, ahumic acid containing precursor waste processed through harmless treatment is added into compost for at least one time. The composting method is used in the field of composting.

Description

technical field [0001] The invention relates to a method for increasing the content of humic acid in compost. Background technique [0002] With the rapid development of China's economy and the rapid increase of population, people's demand for various agricultural products will also generate a lot of waste, and its emissions have already ranked first in the world. Harmful wastes have not been properly and harmlessly treated, and have not been effectively and rationally used, which has caused extremely bad impacts on the environment and ecology. At present, the most convenient, fast, non-polluting and professional treatment method for livestock and poultry manure, straw and other agricultural waste is composting treatment technology. The purpose is to make full use of organic waste, and can very effectively transform the waste into organic fertilizers that can be absorbed and utilized by the land. After composting under appropriate conditions, organic matter can be graduall...
