[Method] The 2nd-sea-son rice was cuItivated in the test with suitabIe temperature, heat water and fertiIiz-er, on basis of stubbIes of the 1st-season rice. Hence, rice can be harvested twice per year, with short growth periods, and high yields, and the cuItivation is simpIe to be operated, avoiding the peak of disease damages, so that pesticides are not re-quired. [Result] The experiment of northward movement of super-earIy rice achieved success in Shenyang on October 9, 2014, with super-earIy maturing japonica rice 8501. [Conclusion] Northward movement of ratoon rice enjoys a promising prospect in increasing crop yield and guaranteeing food security.展开更多
