| Abstract: | The prime cultivation technique of wheat-Mount No.21 was studied with the method of common ratary combinative design with five factors at five levels.The optimal agronomic measure for Mount No.21 with the yield of 8?700～9?300?kg/hm 2 was obtained.It included that the pure base nitrogen was 249.3～260.9?kg/hm 2,the base P 2O 5 102.9～109.1?kg/hm 2,the base K 2O 115.8～129.1?kg/hm 2,the sowing date was from 3 October to 5 October,the sowing amount was 159.6～166.1?kg/hm 2 and ratio of base nitrogen and its supplement in jointing stage was 4∶6. |
