Abstract: A preliminary study on the circulating harvest of feeding rape was carried out. Results showed that circulating harvest of feeding rape can be done by harvesting twice or more in different field alternately per growth cycle. Circulating harvest of feeding rape will not reduce the annual yield, but also relieve the shortage of fresh feed during winter and spring, so increased its planting value. Harvest times and the first harvest time can be determined according to its sowing time and growing situation, it will be more economical by harvesting two to three times and topdressing one time in a appropriate amount per growth cycle.
