The goal of the study was to find the best way to grow a specific type of hybrid rice called Liangyou 6326. The researchers tested different planting densities and fertilizer levels to see which combination produced the highest yields. They found that the best cultivation model for Liangyou 6326 is to plant at a density of 22.5×104 plants per hectare and use specific amounts of urea, potassium chloride, and superphosphate as fertilizers at different growth stages. This model resulted in the highest actual and theoretical yields compared to other combinations tested.
