The study on the interrelationships among the 5 factors of cultivating measurements (base N-fertilizer, supplementary N-fertilizer, P-fertilizer, K-fertilizer, seeding density) and output in winter wheat Lin-Mai 2 by applying the design of perpendicularity rotational combination in High Productivity Field. The results showed that The yield mathematical model establish by means of adjusting optimization together with analysis, Defining the key divisors and synthetical agronomy measurements that the winter wheat yields of Lin-Mai 2 to growing that high production high efficiency optimizes, good means forms a complete system in the interest of the improved variety in High Productivity Field. The results showed that applying more N-fertilizer and P-fertilizer were the key measurements in the So-called optimum cultivation of winter wheat Lin-Mai 2. It also showed that more P-fertilizer applied made N-fertilizer more effective. The optimum cultivation measurements of winter wheat Lin-Mai 2 for high output high economic benefit were fundamental seeding 181.8 to 229.2 ten thousand per hm2, base N-fertilizer 121.95 to 141.3 kg/hm2, P-fertilizer 195 kg/hm2, K-fertilizer 33.75 to 60.75 kg/hm2 and chase N-fertilizer 71.7 to 83.7kg/hm2 in leave stage.
