Abstract:The notill planter in horizontal residuethrowing fingerwheel type for maize was designed. The residuethrowing fingerwheel, furrow opener, seeding and covering device were mainly analyzed. Furthermore, the key parameters were analyzed and determined. The field experiment showed that, though adopting the anti-blocking principle that combined horizontal residuethrowing fingerwheel device with residuecutting by knife type opener, the machine could solve the residue and weed blocking effectively and show a good performance of passing and cutting stubble. Compared with striprotating maize notillage planter, the maize notill planter could not only seed and fertilize at the suitable depths, but also decrease soil disturbance and fuel consumption by 69.7% and 19.3%, respectively. It indicated that this new planter could meet the requirements of agronomy.
