A precision seed planter can plant 10 seeds per revolution of the metering plate with a row to row distance of $450 \mathrm{~mm}$ at a speed of $6 \mathrm{~km} \mathrm{~h}^{-1}$. A plant population of 36 plants per square meter is desired for the crop. The germination percentage of the seed is $90 \% .$ If the planter ground wheel has a rolling radius of $350 \mathrm{~mm}$, the speed ratio of metering plate to the ground wheel required to obtain the desired plant population is_______________
