用 5个两系杂交早稻组合作再生稻栽培试验 ,结果表明 ,各组合均能达到高产、早熟、低耗、优质的目的。再生季产量最高的接近 4 .8t hm2 ,再生季日产量最高的达 10 8.4kg·hm-2 ·d-1,有 4个组合两季总产超过 10t hm2 。供试组合中 ,强势节位除株两优 971为倒 3节外 ,均为倒 2节 ,强势节的再生出穗率最高 ,成穗质量最好 ,占产量的比重最大。在再生稻丰产栽培中 ,应力争强势节位成穗和争取多穗 ,以获得高产。此外 ,如果选用优质组合 ,两季均可产出优质米 ,从而可以解决早籼米质不良问题
Five two-line early-maturing hybrid rice combinations were used for the cultivation of ratoon rice. The results showed that all the combinations could achieve high yield, early maturity, low consumption and high quality. The reclamation season had the highest yield of nearly 4. 8t hm2, and the highest daily production of 10 8.4kg · hm-2 · d-1 in the reclamation season with 4 combinations of more than 10t hm2 in two seasons. Test combinations, the strong node in addition to Liangyou 971 down 3, are down 2, the festival of the highest rate of regeneration of the ear, ear quality is best, accounting for the largest proportion of production. In the cultivation of ratoon rice, we should strive to become a strong node and spike multiple ears to obtain high yield. In addition, high-quality rice can be produced in both seasons if the high-quality combination is selected so that the poor quality of indica rice can be solved
