Abstract:

To effectively relieve the pressure from population, environment and resources, it is very important to develop plant factory. Intelligent plant factory is an advanced stage in the development of facility agriculture. It is a new topic to study how to apply machine learning in plant factory to effectively improve the production efficiency and promote the intelligent development of plant factory. Combining machine learning with crop phenotype study, a crop growth model is established and applied to plant growth environment monitoring (diseases, insects, grass, drought and water logging, nutrition, etc.), accurate plant factory indoor environment regulation, and intelligent nutrient solution regulation etc., so as to solve the problem of high cost and low crop yield of plant factories in China. The study can help plant factories develop towards the one with information technology, automation, intelligence, precision and individuation.

Key words: machine learning, plant factory, research, current status, challenge
