In order to explore the impact of different farming and cultivation of super hybrid rice yield and physiological characteristics, the first four years on the basis of super rice and oilseed rape the revaccination positioning test, 2008 Liangyoupei nine as the material in Changsha tillage transplanting, tilling live, no-tillage transplanting and tillage Daejeon comparison test, the results are as follows: 1. Different Cultivation yield differences between treatment significantly, with the first four years of test results are not consistent. 2008 test tillage transplanting yield reached 11.25t/hm ~ 2, significantly higher than the other three treatments. Yield components in live conditions, no-till rice grains per panicle, harvest index and grain weight than plowing rice, an increase of 0.7%, 0.4% and 1.2%, respectively. Effective plowing rice panicles, the total number of spikelets, grain weight are higher than the no-till rice transplanting conditions, an increase of 10.4%, 10.7%, 1.1%, seed rate differences between each treatment. Without theory under tillage or no-tillage, seeding rice spike higher than transplanted rice, the difference reached a significant level. 2 Different Cultivation, nutrient uptake significantly different between treatments. In tillage or no-till conditions, live processing aboveground plant N uptake than transplanting processing, the former for 250.77 ~ 263.35kg/hm 2, the latter to 217.49 ~ 225.90 kg / hm ~~, differences up to a significant level. Either live or in transplanting conditions, CT. Aboveground plant nitrogen uptake is higher than the no-tillage treatment, but the difference was not significant. Different Cultivation processing plants Phosphorus and Potassium and nitrogen uptake changes are basically the same. The 3 Different Cultivation processing significantly between plant height and ear length differences. Which under different tillage patterns of plant height highest tillage transplanting rice, plowing rice minimum, and regardless of tillage or no-till transplanted rice plant height than direct seeding rice. 4 Different Cultivation flag leaf physiological activity. Either no-tillage or plowing, seeding rice and transplanted rice flag leaf peroxidase activity decreased after the first increase in the content of soluble protein and soluble sugar content of the four farming methods downward trend less membrane lipid peroxidation The oxidation product malondialdehyde content increased significantly at 25 d after full heading. Comparison with plowing rice, no-till rice showed leaf senescence and grain dry matter accumulation.
