Utilization of duck dung:
First, it is used as raw material for biogas production.
Poultry has been considered as a good raw material for biogas production. Duck manure is fermented by biogas and can not only produce cheap and convenient energy - biogas, but also the residue after fermentation is a high-quality organic fertilizer.
Second, as a feed for aquaculture.
Third, used as fertilizer.
Duck manure is a high-quality fertilizer with rich N, P, and K contents. It can be used in farmland to improve soil, increase organic matter, and increase soil fertility. Under the modern production conditions of farm farming, the technology of heaping, smashing and mechanical spreading of duck dung can be solved, and its application prospects and effects will be even more remarkable. It is envisaged that the duck dung regularly collected at the duck farm will be transported to the Tiantou Yard, sealed with plastic film, fermented and killed, and then mechanically crushed before the summer and autumn sowing, and then applied to the field with a fertilizing machine as rice and wheat. The base fertilizer. However, this program did not play its role of reuse.
4. Chicken, duck dung, and other poultry dung are the main sources of phosphate fertilizers and are suitable for all types of flowers, especially for the use of fruit.
Chicken and duck dung is a high-quality fertilizer with high fertilizer efficiency, low cost, and wide source. The frequent use of chicken, duck, and feces can not only improve the soil, loosen and fertile the soil, but also increase the ability to retain fertilizer and water, and the flower grows vigorously and has many branches. Large leaves, large flowers, long flowering period. However, it should be noted that raw chicken and duck dung cannot be applied directly and must be fermented and cooked before use.
The use method is: When the flower is on the basin or change basin, use a flower pot with a diameter of 20 cm, spread about 100 grams of decomposed chicken, duck and manure around the basin or basin, and cover it with a layer of soil as a base fertilizer. Do not allow flower roots to come in direct contact with fertilizers. It can also be used as a top dressing. The smashed chicken, duck and dung can be sprinkled around the top surface of the pot, covering a thin layer of soil.
