Embodiment 1

[0017] The particle size is 5-10mm, the specific surface area is 100m 2 The biochar of / g is soaked in the wood acetic acid solution of 10% by mass fraction for 0.5h, obtains the deodorant with biochar as carrier, adds the deodorant of 0.5% of compost raw material quality of one deck at the bottom of compost container, Add chicken manure and leaves with a mass ratio of 1:9 as compost raw materials, then add 3.5% deodorant by mass of compost raw materials, stir and mix thoroughly, and finally cover a layer of deodorant with 1% mass of compost raw materials on the surface of the heap Add appropriate water to make compost after the moisture content is 50%-60%. During composting, stir 3 times a day; after 55 days composting reaches maturity, drying and granulating to make odorless organic fertilizer containing biochar.

[0018] This method obtains an organic fertilizer with a nitrogen content of 2.95%, a sulfur content of 0.35%, a biochar content of 1%, a moisture content of 7-14...

Embodiment 2

[0020] The particle size is 11-16mm, the specific surface area is 150m 2 The biochar / g is soaked in the wood acetic acid solution of 15% by mass fraction for 1h to obtain the deodorant with biochar as the carrier. Add a layer of 1.5% deodorant of the compost raw material mass at the bottom of the compost container, and add the mass ratio Pig manure and straw at a ratio of 1:1 are used as compost raw materials, and then add 5% deodorant of compost raw material mass and stir and mix, and finally cover a layer of 0.5% compost raw material mass deodorant on the surface of the heap, Moisture makes the moisture content 50%-60%, compost after stirring and mixing. During the composting period, stir 3 times a day. After 43 days, the compost reaches maturity, dried and granulated to make an odorless organic fertilizer containing biochar.

[0021] This method obtains an organic fertilizer with a nitrogen content of 2.95%, a sulfur content of 0.26%, a biochar content of 1.5%, a moisture c...

Embodiment 3

[0023] The particle size is 1-5mm, the specific surface area is 200m 2 The biochar / g is soaked in the wood acetic acid solution of 0.2% by mass fraction for 2h to obtain the deodorant with biochar as the carrier. Add a layer of 0.5% deodorant of the mass of compost raw materials at the bottom of the compost container, add mass Cow dung and straw with a ratio of 9:1 are used as compost raw materials, and then 3% deodorant of the mass of compost raw materials is added, and finally a layer of deodorant of 1.5% of the mass of compost raw materials is covered on the surface of the heap, and appropriate water is added to make The moisture content is 50%-60%. After stirring and mixing, compost is carried out. During the composting period, the compost is stirred 3 times a day. After 59 days, the compost reaches maturity, dried and granulated to make an odorless organic fertilizer containing biochar.

[0024] This method obtains an organic fertilizer with a nitrogen content of 2.95%, a...

Abstract

The invention discloses an odorless organic fertilizer containing charcoal and a preparation method thereof. The preparation method comprises the following steps: soaking charcoal in a wood vinegar solution so as to obtain a deodorizer which takes charcoal as a carrier; adding the deodorizer into a compost raw material, adding a proper amount of water, and then performing fermentation composting; and after compost is in a thoroughly decomposed stage, drying the mixed fertilizer, and granulating to obtain the odorless organic fertilizer containing charcoal. The odorless organic fertilizer containing charcoal can be used for greatly improving the soil organic matter content, effectively improving the soil structure and improving the moisture and nutrient retaining capability of soil. During an organic fertilizer production process, the deodorizer is added, so that not only is the composting process rapidly and efficiently performed in an environment-friendly manner, but also the user effects of the charcoal and the organic fertilizer are obviously improved; the charcoal is added into the compost raw material, so that the composting temperature can be well kept, the microbial growth is promoted, and therefore the composting period is shortened; and more importantly, the charcoal is capable of effectively absorbing ammonia and hydrogen sulfide, so that nitrogen and sulphur losses in the composting process are reduced.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an odorless organic fertilizer containing biochar and a preparation method thereof. Background technique [0002] In the process of agricultural production and animal husbandry production in my country, up to 800 million tons of straw and 400 million tons of livestock manure and other biomass solid waste are produced every year. Environmental problems, such as air pollution caused by straw burning, odor and water pollution caused by the discharge of poultry manure, on the other hand, both straw and poultry manure are rich in organic matter, and poultry manure is also rich in nitrogen and phosphorus , can be used to improve soil nutrients. However, the current agricultural production puts too much emphasis on increasing food production, using a large amount of chemical fertilizers and pesticides, and the use of organic fertilizers has not been effectively paid attention to. Part of it enters the wa...
