Chicken manure fermentation has the following methods:
1. The plastic bag is cooked. A plastic tube of 7-8 meters in length is fastened with a thin string at one end and placed between rows of vegetables. Fill the 150-200 kg of chicken droppings from the other end of the bag. Leave an appropriate gap in the bag and do not overfill it. Then, fill in the water, the amount of water to submerge the chicken manure is appropriate, and then tighten the mouth fermentation, 5-6 days to completely decomposed. Note that both ends of the plastic tube must be tightly closed, and it is advisable to use water which does not flow out. If it is necessary to accelerate the rate of decomposing and prevent complete decomposedness, add fertilizers with higher fertility. This method is simple and easy to operate, fast decomposing, will not cause harm to the vegetables in the greenhouse.
2. Composting Natural Decomposition The chicken manure to be decomposed is spread on the concrete floor or on the mud covered plastic film, and the chicken manure is piled into a 1.5-2 m wide and 1.5-3 m wide bun, and the chicken is kept in the long-term view of the site size and the chicken. How much feces may be. The appropriate amount of water (about 55%) is added, and then the plastic film is covered, so that the compost naturally heats up to 50° C. and kills pathogenic bacteria and parasite eggs. Pay attention to the dung heap should not be too tight, so as to avoid the lack of oxygen, microorganisms can not reproduce in large quantities, can be mixed in a certain amount of sawdust, sorghum or straw, wheat, corn and other crop stalks, and make the film and manure piles have a certain gap, To increase air permeability, supplement oxygen, and promote the rapid and large-scale propagation of microorganisms. It is also possible to sprinkle calcium sulphate, zeolite, raw soil and other adsorbents in chicken manure to absorb the odor produced during fermentation.
3. The biological agent is cooked as described above, but before decomposing, the decomposing agent such as stimulant antibacterial 968 is evenly sprayed onto the chicken manure and then piled or dumped into the soil to quickly deodorize and decompose. Decomposing chicken manure in this way is fast and effective.
4. Handan processing Put the specially-raised carcass into the device that holds the chicken manure, and excrete the manure by digesting it and use it directly as a fertilizer without fermentation. The law can save energy, use the ecological cycle of nature, make chicken manure harmless, but the treatment is small, the treated chicken manure has high water content.
5. Decomposed ripening pool in the greenhouse In the western end of the greenhouse, a pool with a volume of about 2 cubic meters is built on the shed, chicken droppings are put into the greenhouse, and fertilization agents with high fertility are added to ripen and then vegetables are washed out. However, in the shed, it is necessary to take care not to perform the ventilation during the severe winter and cloudy snow weather, so as to avoid excessive accumulation of harmful gases such as ammonia in the shed during the decomposing process, causing gas damage. This method is mainly aimed at the release of heat and carbon dioxide from chicken manure during the decomposing process. These are the most needed vegetables in the winter shed.
Preparation of Fenebute
1. Prepare the first intermediate
Benzaldehyde and ethyl acetoacetate into ethanol, stir at room temperature under the catalysis of organic alkali reaction with filter cake filtration after 45 ~ 50 h, after the completion of the filter with ethanol elution filter cake, dry cake solids, then ethanol filtrate concentrated to a quarter of the original volume, to cold, concentrate filtering alcohol washing, solid, merging two solid is the first intermediate; The mole ratio of benzaldehyde, ethyl acetoacetate and ethanol is 1:2.5 -3:12-15.
2. Prepare the second intermediate
The first intermediate is added to the mass concentration of 20% sodium hydroxide solution, and the reaction is stirred at 85-90°C for 2-5 hours. After filtration, the filter cake is used for filtration. After filtration, the filter cake is washed, the filtrate is combined and cooled, and the filtrate is cooled by stirring for 3h. Solid second intermediate; The mass ratio of the first intermediate to the sodium hydroxide solution is I: 1.8-2.0;
3. Prepare the third intermediate
The second intermediate was dissolved in pure acetic anhydride solution for reflux 3 ~ 5h. After the reflux, the acetic anhydride was concentrated and dissolved with toluene. After the dissolution, ammonia water was added, and the reaction took place at 60_65°C for 1 ~ 1.5 h. Filtrate, wash and dry the precipitated solid to get the solid third intermediate; The mass ratio of the second intermediate, pure acetic anhydride solution, toluene and ammonia water is 5:1-1.2:0.5-0.8:0.5-0.8;
4. Prepare Finebute
The third intermediate was dissolved in 25% sodium hydroxide solution and cooled to _5°C ~ 10°C. After cooling, sodium hypochlorite was added slowly within 15-20min for 1h reaction, followed by ice bath reaction of 0.5 ~ 1.5 h and water bath reaction of 0.5 ~ 1.5 h. Finally, the temperature was gradually increased to 60 ~ 80°C for 1-5 h, and the reaction was cooled again after completion. After cooling, hydrochloric acid was added in the ice water bath to adjust the PH to 2, and the decolorization was stirred at room temperature. After filtration, sodium hydroxide was added in the ice water bath to adjust the PH to 6-7, and the cooling was stirred for 2 hours. The mass ratio of the third intermediate, sodium hydroxide solution and sodium hypochlorite is 1.0:0.8-1.0:1.0-1.1.
