摘要:

长江中下游地区梅雨季节的洪涝常常导致安徽水稻生产田受淹并成灾。本文研究比较了不同淹水深度和淹水天数对两系杂交籼稻两优240生育性状、经济性状和产量的影响。结果表明,随着淹水深度和淹水天数的增加,两优240的生育期推迟、有效穗数减少、产量下降。该研究可为长江中下游地区一季中稻在受涝后及时补改种提供参考。

Abstract:

Floods during the Meiyu season in the middle and lower reaches of the Yangtze River often lead to flooding and disasters in Anhui’s rice fields. The effects of different submerged time and depth on growth traits, economic traits and yield of two-line indica hybrid rice Liangyou 240 were studied. The results showed that with the increase of flooding depth and flooding water days, the growth period of rice was delayed, the effective panicles and the yield decreased. The study provides a reference for single-season indica rice in the middle and lower reaches of the Yangtze River to replant in time after waterlogging.

Key words: single-season indica rice, flood disaster, technical countermeasure, middle and lower reaches of Yangtze River
