具有较强生长优势的籼型三系杂交稻问世,特别是杂交稻早中熟组合的育成,为水稻的再生利用开创了新的前景。我们在大量考察的基础上,从1984年起正式进行了三年的杂交稻再生利用研究,较为系统地作了各有关单因子和综合高产的田间试验与室内研究,并采取试验与示范同步进行的方法,获得了预期结果。 The advent of three-line indica hybrid rice with strong growth advantages, especially the combination of early maturing and medium maturity of hybrid rice, has opened up a new prospect for the regeneration of rice. On the basis of a large number of surveys, we conducted a formal study on the recycling of hybrid rice for three years from 1984 and systematically made field and laboratory studies on single-factor and comprehensive high-yield fields and conducted experiments and demonstrations simultaneously The method to obtain the expected results.
