What are the uses of chicken manure? How is it made? Experienced netizens are asked to help explainWith the improvement of living standards, chicken and eggs have become common foods on the dining table, and at the same time the scale of chicken farming has gradually expanded, producing large amounts of chicken manure. But chicken manure looks dirty and smelly, and also pollutes the environment, becoming a headache for large-scale chicken farmers. Therefore Zhongdi Network has compiled the uses and operation methods of chicken manure, listed in detail below for netizens' reference.
Uses of chicken manure:
According to research by researchers, chicken manure contains: 25.5% organic matter, 1.63% nitrogen, 1.54% phosphoric acid, 0.82% potassium, calcium, 27.79% protein, and contains 18 kinds of amino acids, and the content of lysine and methionine is higher than that of feed such as sorghum, corn, and barley, 12% crude fiber, 32.58% nitrogen-free extract, about 23% crude ash and rich B-group vitamins, and also contains some beneficial factor that promotes animal growth.
Therefore chicken manure can be fermented into fertilizer or feed, and can also be used directly as biogas raw material.
Chicken manure can be fermented into organic fertilizer by adding microorganisms, because the nutrients contained in chicken manure are very high, such as crude protein, organic matter, trace elements, etc. These nutrients are also essential nutrients for crops, and chicken manure organic fertilizer has the effects of nitrogen fixation, phosphate solubilization, and potassium solubilization, and also contains rich organic matter and 16 kinds of trace elements.
How to make chicken manure organic fertilizer:
Step 1, selection of chicken manure:
Dry chicken manure: since dry chicken manure lacks water and cannot ferment, sufficient water must be added, and after sufficient water is added, pile it into a large heap, then ferment, covering it with sealed plastic sheeting, so that fermentation will be faster.
Fresh chicken manure: if it is fresh chicken manure, various auxiliary materials also need to be added during fermentation to absorb the water in the fresh chicken manure; too much water easily leads to poor ventilation, and microorganisms cannot produce fermentation. The choice of auxiliary materials is diverse, and the purpose is to absorb part of the water in the fresh chicken manure. Auxiliary materials are generally chosen as: sawdust, straw, plant ash carbon, etc. The added ratio is about: 70% chicken manure, 30% auxiliary materials, and the adjustment of this ratio should be flexibly prepared according to the local soil quality and nutrient composition. For making fruit tree fertilizer or animal feed, strains etc. must be added. Strains are available on the market.
Step 2, preparation before mixing:
Generally use 700 kg of wet chicken manure, 300 kg of wheat bran or rice bran or straw powder, and 0.25 kg of chicken manure fermentation agent strain; pour 0.25 kg of chicken manure fermentation agent strain into water, dilute and stir evenly. The dilution water is best well water or river water, and stir for 10-30 minutes.
Step 3, making chicken manure organic fertilizer:
First mix the chicken manure with wheat bran or rice bran or straw powder for 2 minutes, then pour in the strain dilution liquid and stir for 6 minutes; then pile it into a heap about 1 m high, no more than 1.5-2 m wide, with unlimited length. Control the moisture at about 40% (Note: increase or decrease the amount of dilution water depending on the dryness and wetness of the fermentation raw materials; the diluted strain water should be about 35%-40% of the fermentation raw materials, and it is best when mixed so that it forms a ball in the hand, water is seen between the fingers but no droplets fall, and it breaks apart when the hand is released.
Note: too much water easily makes it sour, too little and fermentation is incomplete. If the fermentation raw materials are relatively wet, reduce the amount of dilution water); and punch holes in the top of the heap for ventilation; finally cover the fertilizer heap with rectangular plastic sheeting, with the plastic sheeting connected to the ground, and press a heavy object every 1 m, so that the inside of the film is both ventilated and avoids being bulged up by strong wind.
Fermentation time of chicken manure organic fertilizer: generally more than one month in winter, and generally 1-2 cycles of about 14-21 days in summer.
Precautions for making chicken manure organic fertilizer:
1. Chicken manure must be fermented and decomposed before it can be used on crops, otherwise some pathogenic microorganisms in the chicken manure will burn the crop roots. Drying and sun-drying are both acceptable, but after sun-drying, part of the nutrients in the chicken manure will be lost. Chicken manure dried with a dryer can achieve the drying purpose and can also achieve the deodorizing purpose. It can also reduce manual labor intensity, etc.
2. In summer and autumn, the film should be uncovered once in the morning and evening for ventilation (1-2 hours). When the weather is clear, it can be uncovered in the evening of the previous day and covered again in the morning of the next day. After 4-6 days of composting, the heap temperature can rise to 60-70°C. After 10 days of composting, the heap can be turned once, and after 20 days of composting it can be thoroughly decomposed, the fertilizer content is increased, and harmful insects are eliminated.
Chicken manure contains large amounts of incompletely digested protein, trace elements, etc. As long as it undergoes microbial fermentation and proper processing to remove harmful substances in the chicken manure, chicken manure can be used as very good feed such as pig feed and fish feed.
How to make chicken manure feed:
Method 1,Mix fresh pure chicken manure with chopped forage grass, fruit and vegetable waste, or potato, sweet potato vines, grain, etc. and then ensile, among which ensiling with non-legume forage grass is best.
During ensiling, maintain a moisture content of 40%-75%, corn and other grains can be added, and an appropriate amount of ammonium hydroxide can be added to improve the digestibility and palatability of the forage and chicken manure silage. After air-drying fresh chicken manure, ensile it at a ratio of 30% in green corn, then feed it to beef cattle; it can almost rival soybean cake corn silage, and the crude protein content is relatively high.
Method 2,Fresh pure chicken manure can be directly fed to pigs and fish. When feeding, add it according to the different effective components contained in different chicken manure. For example, young chicken manure contains relatively high crude protein and can be used as concentrated feed, while laying hen manure has a relatively high ash content, so attention should be paid when adding it. When feeding fish, add it directly into the fish pond.
