摘  要:
After analyzing science and application value of precision irrigation in orchard,the results in this filed were summed up.It was found that in the future,sap flux,stem diameter variation,and canopy-air temperature difference of fruit trees are most useful among all of water status diagnose methods.Based on evolution of theory and products in precision irrigation of orchard,research contents and direction in the future were generated.Last,it was put forward that the key points to be solved in the future are to reduce the cost and realize intelligent.
