摘要
本文探讨了淹水条件下红麻生长发育及营养吸收特点．结果表明淹水影响红麻根系的发育和生活力，养分的吸收与运输受阻而富集于麻株茎部，从而导致红麻叶片大量脱落，麻株生长停滞，光合强度降低，干物质积累量减少，茎杆木质素含量增加，纤维素合量减少。播种早的麻株耐淹能力明显大于播种迟的麻株。
Studies were carried out on the development and nutritive absorption for kenaf growing under waterlogging condition. It showed that the development and viability of kenaf roots were affacted .the absorption and transportation of nutritive substance were inhibited and hence were accumulated in the stalk. Which caused the drop of leaf in quantity,the delay of growth,the reduction of photosynthetic intensity and dry matter accumulation. With the increase of lignin and decrease of cellulose in the stalk. It also showed that the waterlogging resistance of kenaf sown forward was higher than that of kenaf sown afterward.
