Adopting the quadratic regression rotation design,a series of research about the comprehensive agronomic practice of effectting wheat yield,the quantit y of supplying coal-fly-ash,the density of planting wheat and irrigating amoun t had been conducted for two years at Chao soil area in East Henan Province.The regression model on yield were established,and the compre- hensive agronomic pra ctice for wheat yield being respectively higher than 6600,6150,5700kg/hm2 and their maxium economic benefit were suggested by the optimum seeking method.
