超早熟再生稻北移及高产栽培技术

摘要

[目的]探讨超早熟再生稻北移及高产栽培技术。[方法]利用一季水稻收割后稻桩上的再生芽开始萌发，在适宜的温、光、水、肥条件下培育出的第二再生季稻。其特点是一种两收、生育期短、产量高、六省、简便、米质优，成熟期短，避开了病虫害的高发期，整个生育期不需要任何喷洒农药等。[结果]超早熟再生稻北移是2014年10月9日在沈阳成功收获。所用品种为超早熟粳稻8501。[结论]再生稻北移种植对我国北方粮食增产和食品安全具有广阔的发展前景。%Objective] The alm was to expIore northward movement and highIy-quali-fied cuItivation technoIogy of super-earIy maturing ratoon rice. [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.
