The half-precision fertilization seeder of rice and wheat is designed against the problems of large straw mulching quantity, high soil water content, the traditional rice and wheat seeder easily blocked and poor fertilization seeding uniformity in Jianghuai region. The machine uses the rotary tillage stubble cleaning way to actively block and improves the traditional furrowing fertilization seeding method easy to cause winding grass. Electric control mode is used to drive the seed fertilizer shaft for sowing and fertilizing, the machine can carry on the straw returning to field, applying fertilizer, sowing, covering earth, rolling and other operations at one time, and can achieve the goal of half-precision fertilization seeding rice and wheat. The test results show that the machine has good anti-blocking performance and high operation efficiency. It works stably and reliably, and the various technical indexes meet the requirements of precision and half-precision mechanization planting, suitable for rice and wheat.
