| Abstract: | A 2-degree common rotary design was used in computer simulating selection and system deciion-making analysis to analyze the main agronomical practice for high-yield maize in Zhelimu area of Inner Mongolia. Economical comprehensive agronomical practice for the 11250kg/hm2 was determined:density at 77250-79650/hm2;seed manure N at 71. 8-80. 0kg/hm2; seed manure P at 71. 7-80. 8kg/hm2; top dressing N 144. 6-165kg/hm2;application of top dressing N was time manure for earing. |
