Abstract: To explore the influence of different mechanical planting patterns on the economic efficiency of rice production, from 2010 to 2012, comparison test was conducted between bowel-blanket mechanical planting, blanket-like mechanical planting, mechanical direct seeding and manual transplanting in Huaiji County Zhaoqing City, Guangdong Province. Results showed that, the yield of bowel-blanket mechanical planting, blanket-like mechanical planting and mechanical direct seeding in 2010 early season rice was lower than manual transplanting, lower respectively 1.28%, 0.96% and 7.69%. And in 2011, the yield was lower respectively 0.45%, 0.67% and 8.29%, but in 2012, it increased respectively 12.52%, 11.22% and 0.00%. The daily average yield of mechanical direct seeding always was the highest from 2010 to 2012. Comparing with the manual transplanting, the cost of bowel-blanket mechanical planting, blanket-like mechanical planting and mechanical direct seeding in 2010 early season rice decreased significantly, and net profit changed respectively 2.14%, 1.43% and -10.84% . And in 2011, the cost changed respectively 2.28%, 2.28% and -5.90%, and net profit decreased respectively 3.20%, 3.68% and 10.62%. But in 2012, the cost changed respectively 2.28%, 2.28% and -5.90%, and net profit increased significantly. The results showed that, the blanket-like mechanical planting and the bowel-like mechanical planting are more suitable for rice production in Huaiji County Zhaoqing City, but the output fluctuation of mechanical direct seeding is large in different years.
