Description

A composite system of poultry farming and vegetable cultivation

technical field

The invention relates to a composite system of poultry breeding and vegetable planting.

Background technique

With the improvement of living standards, people's requirements for food nutrition are getting higher and higher. Eggs have become an important source of protein intake for people because of their good nutritional value and relatively cheap price. At the same time, people's demand for vegetables is also increasing. Today, as land and arable land resources are increasingly scarce, it is of great significance to create a new farming model that can raise chickens and grow vegetables on the same piece of land. There are three types of chicken houses for raising laying hens: open, semi-open and closed. Open and semi-open chicken houses are easily affected by the external environment, resulting in a decrease in production performance and instability. Closed chicken houses can reduce or even eliminate external influence on the environment in the chicken house through measures such as artificial lighting, mechanical ventilation, and temperature and humidity control. It is beneficial to the good and stable production performance of laying hens. The underground chicken house is a special closed chicken house. Growing vegetables in greenhouses is widely used because it is conducive to the control of some environmental factors such as temperature and humidity, and can grow off-season vegetables or allow vegetables to be put on the market earlier to generate greater benefits. The exhaust gas emitted from the chicken house is mainly CO ₂ and NH ₃ , CO ₂ is the raw material for plant photosynthesis, and NH ₃ can be combined with water to form ammonia water and be used by plants.
