Quadratic regression orthogonal rotation combination design with five factors was used to study the relationship be-tween the yield (y) and sowing time (x1), density (x2), pure N (x3), P2O5 (x4) and K2O (x5) for establishing of mathematical model and developing cultivation technical measures of high yield. The results showed that the comprehensive measures with sowing on April 14~16, 147~153 thousand plants/hm2, 41.20~49.92 kg/hm2 of pure N, 43.99~47.48 kg/hm2 of P2O5 and 36.97~41.03 kg/hm2 of K2O were practical for the yield of more than 1 000.10 kg/hm2.
