【Abstract】 Six-factor ottimal design is adopted in this experiment. A well fit yield functional model is established by using computer, which is verified by feedback test preliminarily. The optimalized agronomic practices of Liangyouxinggmg Nol, an intersubspecties rice hybred combination by tow system method, above the yield level of 8250kg per hectare are obtained through comprehensive analysis and simulative optimalization. The practies are characterized by low fertilizer imput. This paper also discusses the capability of soil nitrogen absorption by this hybred combination.更多还原
