Abstract: Problems such as shallow rotary，low irrigation water utilization efficiency and serious surface runoff were caused by shallow rotation and shallow tillage，it had a seriously impacts on grain production and sustainable development of agriculture in China.Mechanized deep pine operation was a good way to solve this problem.With continuous progress of technology，there are more and more deep pine machinery which are suitable for different regions，different agronomy requires.Deep pine machinery which were widely used in China were introduced，and development ideas and suggestions of mechanical deep pine technology were put forward.
