Abstract:In order to explore the cultivation technology suitable for new w heat cultivar Zhengmai 9962 which was approved by national standards ,a“3414”experiment design was used to study the application amount of nitrogen ,phosphorus and potassium fertilizer recommended for Zhengmai 9962 .The results showed that the nitrogen and phosphorus fertilization increased the grain yield by 44 .22% and 11 .56% ,respectively ,compared to no nitrogen and phosphorus application ,w hile the potassium fertilization increased 2 .51% than no fertilizer .Based on one variable quadratic model regression analysis ,the highest application rate of N ,P2 O5 and K2 O was 206 .01 kg/ha , 128 .28 kg/ha and 89 .18 kg/ha respectively ,and the most economic application rate of them was 178 .57 kg/ha ,93 .06 kg/ha and 0 .2 kg/ha respectively .
