AUTOMATIC CONTROL METHOD AND EQUIPMENT FOR FERTILIZER APPLICATION AND SEEDING

摘要

PURPOSE: A method and an apparatus for automatically controlling seeding and fertilizing amount are provided to improve seeding and fertilizing accuracy. CONSTITUTION: A method for automatically controlling seeding and fertilizing amount is as follows. The speed of a tractor is measured by using a GPS sensor(110). The speed of the tractor is obtained. The ascending and descending availability of a seed metering unit(120) equipped with a seed metering roller is determined. The speed of the tractor is measured by using the GPS sensor when the ascending and descending of the seed metering unit is impossible. A drive motor is driven according to the speed of the drive motor when the ascending and descending of the seed metering unit is possible.
