Study on biological,physilogical bases of 7500kg grain per ha of precision drilling in spring wheat in Hetao irrigation area of Inner Mongolia were conducted. The results showed that it was main development tendency of high-yielding cultivation in spring wheat that the precision drilling was for solving the contradiction of single-plant and its population under high-fertility soil and good irrigation management. The stable yield of 7500kg grain per ha and good economic benefit could be obtained when precision drilling and precision management were used. The cultivation technique of precision drilling in spring wheat was also expounded in details.
