不同麦稻轮作模式产量、资源利用及经济效益分析
Analysis of Yield,Resource Use Efficiency and Economic Benefit in Different Wheat-rice Rotation Systems
摘要
Abstract
Based on the ecological conditions of the Yangtze River area in Nantong,Suluomai No.2,Yangmai 29,Nangeng 46,Nangeng 5055,and Nangeng 9108 were used as research materials to set up 4 wheat-rice rotation combinations:Suluomai No.2-transplanted Nangeng 46,Suluomai No.2-direct seeding Nangeng 5055,Yangmai 29-transplanted Nangeng 5055,and Yangmai 29-direct seeding Nangeng 9108.The application prospects of the"hulless barley-rice"model and the"wheat-rice"model in the Yangtze River area of Nantong were compared by analyzing the correlation between growth characteristics,yield,taste quality of rice,distribution and utilization of temperature,light and water resources,economic benefits,and resource utilization.The results showed that the growth period of Suluomai No.2 was shorter than that of Yangmai 29,and its yield and resource allocation were also lower than Yangmai 29.Yangmai 29-transplanted Nangeng 5055 had the highest yield,but there was no significant difference compared to Suluomai No.2-transplanted Nangeng 46.Suluomai No.2-transplanted Nangeng 46 model had the higher yield,resource allocation than other models,and its yield,effective accumulated temperature,solar radiation,sunlight hours,and rainfall was 8 548.8 kg/hm2,2 616.8 ℃,3 215.4 MJ/m2,1 342.10 h,and 632.7 mm,respectively.Suluomai No.2-transplanted Nangeng 46 had the better taste quality of rice than other models,and its appearance,taste and comprehensive score was 8.40,8.43,and 76.55,respectively.The annual economic benefits of Suluomai No.2-transplanted Nangeng 46 model were 3 465.36,11 847.32,and 11 867.60 yuan/hm2 higher than those of other models.There was a highly significant positive correlation between wheat yield and rice yield and light,temperature and water resources.The annual yield of wheat-rice had a highly significant negative correlation with solar radiation and sunshine hours,and a significant negative correlation with effective accumulated temperature.The Suluomai No.2-transplanted Nangeng 46 model has achieved the best economic benefits,and it is suitable for moderate scale promotion and production in this area.关键词
