Embodiment 6

[0044] Example 6 The preparation method of the conditioner used to reduce the volatilization of ammonia in the chicken manure composting process

[0045] This embodiment is the preparation method of five kinds of conditioners used to reduce ammonia volatilization in the chicken manure composting process provided by Embodiment 1-5, and the method includes the following steps carried out in sequence:

[0046] (1) Dry the fungus sticks, and use a crusher to crush them into 1-3cm fungus residue debris;

[0047] (2) Put the formula amount of fungus residue and formula amount of peat into a dryer to dry, and after drying, use a pulverizer to pulverize, pass through a sieve with a diameter of 5mm and mix well to obtain a mixture A;

[0048] (3) Put the zeolite into a muffle furnace for calcination, the calcination temperature is 200-400°C, the calcination time is 4h, after calcination, grind it finely, and pass through a 200 mesh sieve to obtain the modified zeolite powder; take the ...

Abstract

The invention discloses a conditioner for reducing ammonia volatilization during chicken manure composting and a preparation method of the conditioner. The conditioner is prepared from mushroom dreg, turf, vermiculite, strawcarbon powder, phosphorite powder, modified zeolite powder, calcium bentonite, wood vinegar, monocalcium phosphate and a microbial agent. The conditioner is reasonable in compatibility of all components and good in ammonia volatilization prevention effect, improves the composting quality, and has advantages of physical, chemical and biological conditioners at the same time; the preparation method is simple, and the process is easy to control. The conditioner is applicable to promotion and application in organic fertilizer plants and livestock farms, takes chicken manure as a raw material, and reduces ammonia volatilization produced during composting.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of agricultural organic wastes, in particular to a conditioner for reducing ammonia volatilization during chicken manure composting and a preparation method thereof. Background technique [0002] Livestock manure contains a large amount of nutrients such as nitrogen, phosphorus and potassium and organic matter necessary for crops. Composting is an important link to realize the recycling of livestock and poultry manure resources. However, high-temperature composting of livestock and poultry manure generally has serious nitrogen loss, which not only causes the loss of nutrient resources, reduces the agricultural value of fertilizers, but also pollutes the environment. Ammonia volatilization is the main way of nitrogen loss during high-temperature aerobic composting. Studies have shown that after 25 days of livestock and poultry manure composting, nitrogen loss due to ammonia volati...
