Abstract: 【Objective】 Review and summary of nearly 20 years of plant physiological and ecological status quo and development trend of information monitoring technology, and the analysis of the technology on agricultural production effects, promote plant physiological ecology information monitoring technology to high accuracy the rapidness, wireless remote, the development of the nondestructive dynamic monitoring, which provides the theoretical foundation for the further research of the intelligent sewage sludge and the scientific basis. 【Methods】 Collect relevant literatures at home and abroad, summarize and compare them.【Results】 According to literature records and statistics, the application area of integrated water and fertilizer technology (drip irrigation and fertilization technology) in 2016 has exceeded 4.666,7 million hectares (accounting for 3.46% of the national cultivated land area), and the application area of drip irrigation and fertilization technology (over 95% of the XPCC) in about 59% of xinjiang is close to 2.666,7 million hectares.From cotton, vegetables and other cash crops to wheat, corn and other food crops.Some scholars have explored the intelligent irrigation system based on plant physiological and ecological information monitoring technology and made some progress. However, due to high input cost and imperfect technology, the application area is limited and only confined to the western arid region.【Conclusion】 Intelligent irrigation system based on plant physiological and ecological information monitoring technology has been applied in production and achieved good results in terms of water and fertilizer saving, but its development is limited by high cost and imperfect technology (few guidance on fertilization, certain influence on plant growth, and tedious arrangement and wiring on site, etc.).It is necessary to strengthen the research of plant physiological and ecological information monitoring technology, improve the technology and reduce the cost to promote the development of intelligent irrigation.
