The irrigation test was conducted in Qingan County of Heilongjiang Province,and various parameters were surveyed in field,based on these,this paper recorded,counted and calculated the drainage modulus. Meanwhile,to obtain the regional drainage modulus value of Qingan County in Heilongjiang Provincial drainage modulus contour map,and to calculate the paddy field drainage modulus with formulas,this paper verified the reasonability of the contour map and formula calculation based on these test data.
