The use of artificial climate chambers: The use of artificial climate chambers for cultivating seedlings is a new technology that has been developed in recent years. This is a culturing chamber that can automatically control the temperature, humidity, light, ventilation, and carbon dioxide concentration.
The composition of the artificial climate chamber: The artificial climate chamber is generally composed of two greenhouses, three climate chambers (the size of each chamber may be determined according to the number of nursery), a temperature control room, two temperature-controlled rooms and two refrigerating rooms.
The function of the artificial climate room: The artificial climate room is affiliated with a laboratory for seed disinfection and seedling transplant. The indoor temperature, light, and humidity can be adjusted according to needs. Other important ecological factors such as carbon dioxide content, root humidity, and nutrients can also be adjusted as needed.
Advantages of the artificial climate chamber: The advantages of artificial climate chamber nursery are obvious. Indoors can provide the most suitable conditions for seedlings, and severe weather will not happen here. All the conditions that can give full play to the potential biological capacity of nursery stock can be simulated here. For example, the photoperiod can be controlled to break some of the tree's fall dormancy and increase its growth; some seedlings can be forced to dormancy to accelerate lignification and enhance resistance. Coldness; can increase the temperature or adjust the temperature difference so that the seedlings form a favorable form; can increase the carbon dioxide content, increase the efficiency of photosynthesis, and produce more dry matter.
Others: In order to meet the cyclical development of seedling growth, the artificial climate room can exchange spring, summer, autumn and winter seasons in one quarter, thereby greatly shortening the growth and development cycle of seedlings. According to relevant reports at home and abroad, in the artificial climate room, 2 to 3 seedlings can be cultivated in one year. It seems that the use of artificial climate rooms to cultivate tree seedlings has great prospects for development.
The non-standard flange is also called custom flange,it means the flange is not as per the international standard of flanges. Commonly it is designed for special application.
