摘要： 浙江沿海常受台风的影响，台风过后，成片水稻发生倒伏或被水淹，给水稻等粮食生产带来了巨大损失。本试验发现，倒伏后的水稻产量损失达29.30%，而倒伏后人工扶正的产量损失会更大，达35.47%。可见，因台风暴雨所致的水稻倒伏，试图通过扶正来挽回产量损失是不经济的。

Abstract: Rice production is often affected by the typhoon in Zhejiang coastal area. After a typhoon, piece of rice lodging or under water, lead to great loss in rice production. The effects of rice yields lose by uprearing loged rice was studied in rice after typhoon. The results showed that the yield losses was 29.30% after lodging, the yield losses of uprearing lodged rice was 35.47%. Therefore, it is no use for reducing yield losses by uprearing lodged rice.

Key words: rice, typhoon, lodging, grain yield
