选用杂交稻雁两优498和优质稻爱华5号为试验材料,研究了不同钙肥水平下,水稻对钙的吸收积累及分配。结果表明,不同钙肥水平对水稻吸收积累钙具有显著影响。各施钙处理间以施Ca(OH)2450kghm-2和600kghm-2效果最好,在生育后期根系伤流量、伤流液以及各器官中钙含量均显著高于其他处理和不施钙对照(CK)。杂交稻雁两优498在同量施肥水平下,积累钙的能力强于优质稻爱华5号。
The hybrid rice Yan-geng Liangyou 498 and the high quality rice AIHUA-5 were selected as experimental materials to study the absorption and accumulation of calcium and its distribution in rice under different levels of calcium fertilizer. The results showed that different levels of calcium fertilizer had a significant effect on the accumulation of calcium in rice. The effects of applying Ca (OH) 2450kghm-2 and 600kghm-2 were the best among all treatments, and the root trauma, wound fluid and the contents of calcium in various organs were significantly higher than those of other treatments and no calcium control CK). Hybrid rice wild goose Liangyou 498 in the same amount of fertilization level, the ability to accumulate calcium stronger than high-quality rice Aihua 5.
