Title: Benefit Analysis on Super Rice+Ratooning Rice in Different Cultivated Modes
Abstract: [Objective] The study aimed to discuss the benefit analysis on super rice+ ratooning rice in different cultivated modes.[Method] With 4 super rices such as Zhongzheyou 1 as the materials,the cultivation demonstrating projects of super rice+ ratooning rice were conducted in the areas of traditional mid-rice,winter chili,winter vegetables and potato,double-crop rice in Qinzhou City of Guangxi in 2009,with the demonstrating area of 167.9 hm2.[Result] Popularizing the super rice + ratoon rice model could significantly increase the rice yield in the traditional mid-rice and winter chilli cultivation area.The model could reduce the some rice yield in the winter vegetables and potato area,but it could let farmers have a loose time in the arrangement of three crops or more crops a year so as to ensure their yield increase and income increase in the winter crops.The model could have slightly lower yield in the double-crop rice area,but it could save the time of about 1 month,which made the famers have full time to replant a winter crop.[Conclusion] Using the super rice + ratoon rice model could shorten the whole growth period of rice by about 1 month with the yield that was little difference with the double-crop rice and had characteristic of saving seeds,saving work and saving water,etc.
