1、 Can you raise it
The greenhouse can grow flowers, not flowers in it. In the northern region, due to a period of low temperature weather, some flowers are difficult to safely cross the winter indoors and outdoors, so they need to be raised in the greenhouse. The temperature can ensure that they can survive the winter safely. They are made of transparent materials and can also absorb sunlight without hindering their growth. However, raising flowers in greenhouse is not always an advantage, but also has disadvantages p>
2、 Shortcomings
1. Poor ventilation: the greenhouse is covered with a layer of plastic film or glass, resulting in increased humidity, poor ventilation conditions, and it is difficult for plants to contact fresh air p>
2. Occurrence of gas damage: flowers in the greenhouse, which grow in a closed environment for a long time, are easy to suffer from harmful gases. The common ones are ammonia, sulfur dioxide, nitrous acid, carbon monoxide, etc., which will lead to poor plant growth and development. In serious cases, it may also lead to wilting and death after a period of time. If you are raised in a greenhouse, you must pay attention to the prevention and occurrence of harmful gases p>
3. Prone to diseases: long-term poor ventilation will also easily infect diseases, resulting in problems in leaves and stems p>
