| 摘 要： | 以嘉58和甬优12为供试材料,进行了稻田不同干旱程度对水稻生长和产量影响的研究。结果表明,重度干旱（田间裂缝深30 cm）导致水稻株高降低,茎、叶、穗干物质量下降,减产30%以上。减产的原因主要是穗子变小,结实率下降。 |
| 关 键 词： | 水稻 干旱 生长 产量 |

| Abstract: | The effects of different drought degrees on growth and yield of rice Jia 58 and Yongyou 12 were studied. The results showed that the severe drought （field fracture 30 cm） induced the decrease of rice plant height, dry biomass and yield. The main causes of yield decrease were small spike and the decrease of seed setting rate. |
| Keywords: | rice drought growth yield |
