摘要
干旱是水稻生产的重要灾害之一,引起水稻生长发育受阻,生育期显著减慢,造成严重减产。文章在介绍干旱对水稻生长发育影响的基础上,探讨了水稻抗旱的生理生化机制及提高抗旱性的途径。
Drought is one of the most important disasters of rice,and it often stunts the growth and development,slows down the stages significantly and reduces yield output of rice severely. Based on the introduction of the effects of drought on growth and development of rice,the physiological and biochemical mechanism and approachs to promoting drought resistance of rice are discussed in the paper.
