摘要:

笔者调查了洪涝灾害对早、中稻生产的影响,仔细记录了水稻受淹症状,且对早稻不同熟期、不同受淹时间进行了取样测产和考种,得出初步结论:幼穗坏死、花粉破坏是早稻减产的主要原因,对中稻主要影响是分蘖推迟,生育期延长;处于孕穗至乳熟期被淹没的早稻的临界死苗时间是5.4天,约130 h,全部枯死时间是8天以上;处于分蘖期被淹没的中稻临界死苗时间是6天,约140 h,全部腐烂死亡时间也是8天以上。并提出了施救原则和措施。

Abstract:

The author investigated the flooding of the early impact of rice production, rice flooded the symptoms carefully observed, and different maturity of rice in different time were flooded and the test samples yield monitor species, reached the following preliminary conclusions: Young ear necrosis, cut rice pollen was the main reason for destruction, the main effect of rice tillering delay, prolong the growth period; and was booting to milky stage of rice submerged critical Simiao time was 5.4 days about 130 hours, all the dead time was more than 8 days; in flooded rice tillering stage was the critical time is 6 days Simiao about 140 hours, all the decay time of death is more than 8 days. And put forward the principles and measures for the rescue.
