2BFS-8 rice planting fertilizer machine was developed and it could level the paddy fields, open the furrow, form the ridge, sow, fertilize, press down the seeds and fertilizer simultaneously according to the requirement of rice planting. Seeds were drilled in the ridge and fertilizer was manured in the fertilizer ditch. Improved seed metering device could effectively prevent the clogging of rice seeds. The ditch system enabled the effective management of water and fertilizer to the paddy fields. Laboratory and field tests showed that this machine has fully reached the relevant national standards requirement.
