| Abstract: | The experiment was Conducted with the quadratic orth ogonal rotational Combination destgn to Study the mathematical medel for yield over 250 kg/mu of Mandan 1 Hybrid seed Cultural Practices, and 918 sets of Schemes were selected out, which made Manoan I Hybrid seed yield more than 250 kg/mu at 95% probability. The parameter of the scheme for 250 kg/mu were: Sowing time on April 3. 3600—3800 hills per mu for transplanting. The basal manure: ZnSO_4 13.5kg/mu. organic fertilizer 1800 kg/mu. ammonium carbonate 21.53kg/mu. superphosphate 76.25kg/mu. muriate of potash 15.25 kg/mu. The ammonium carbonate was used as topdressing at different stage: "nurwery ferrtilizer" 21.53kg/mu. "stalk fertilizerr" 21.53kg/mu. "ear fertilizer" 43.06kg/mu. |
