example 1

[0031] Raw materials are mixed according to 50% pig manure (dry), 20% tobacco powder, and 30% rice bran, add 3‰EM biological bacteria preparation, mix evenly, pack about 25 kg in woven bags, and pile up regularly about 1.5 meters high After 3 days, the temperature in the pile can reach 60-70°C, and the woven bags are piled up irregularly, with a pile height of about 1.5 meters; after 10 days, the pile is turned over irregularly; %; According to the needs of customers, you can choose to add appropriate amount of organic or inorganic fertilizers, and trace elements, or directly granulate without adding any substances; then, bag them again and stack them irregularly for 7 days. The stack height is about 1.5 meters and the moisture content is average. Below 20%; packed in oxygen barrier to get finished product. Both the production process and the finished product are not smelly.

example 2

[0033] Raw material pig manure is substituted with cow manure and chicken manure among the example 1, and other preparation methods are identical. Both the production process and the finished product are not smelly.

example 3

[0035] In Example 1, the raw materials are proportioned according to 50% pig manure, 30% tobacco powder, and 20% rice bran, and the other preparation methods are the same. Slight odor during production.

Abstract

The invention discloses a preparing method of organic fertilizer through domestic animal manure, which comprises the following steps: (1) blending and stirring manure, filler and microbe leaven completely and evenly; (2) packing; piling; fermenting; drying; producing semi-product; (3) graining; (4) packing; piling; fermenting; drying; (5) sealing to pack. The manure is pig manure, cow manure, hen manure and duck manure. The filler consists of smoke powder and rice bran. The microbe fertilizing leaven is EM biological bacterium agent. The fermenting method doesn't emit odor gas, which avoids secondary pollution effectively.

Description

1. Technical field [0001] The invention relates to a method for preparing organic fertilizer, in particular to a method for preparing organic fertilizer with livestock and poultry manure. 2. Background technology [0002] There are many ways to produce organic fertilizer from livestock and poultry manure, most of which use anaerobic composting fermentation technology, through manual or mechanical turning, exposure to the sun or mechanical drying. The malodorous gas emitted during the turning process not only harms the human body, but also seriously pollutes the environment; mechanical turning or drying consumes energy and increases costs; exposure to the sun will cause secondary pollution to the environment. As disclosed in Chinese patent 01107539.2, it is a method for producing bio-organic fertilizer by utilizing livestock and poultry manure. It uses mushroom dregs, traditional Chinese medicine dregs and livestock and poultry manure to mix, and adds microorganisms to carry ...
