灌浆期至乳熟期的水稻倒伏,不仅增加了收割成本,浪费劳力,减少产量,给广大农民造成巨大损失,还影响稻米品质,为了进一步探索水稻倒伏对稻谷产量和生产效益的影响程度,提高稻米品质,正确指导灾后生产自救,2007年9月开始就水稻倒伏扶正进行多项试验,试验结果表明,水稻倒伏后扶正比不扶正亩效益增加明显;并且水稻同一时间倒伏不同时间扶正,随着扶正时间的推迟而产量不断减少,扶正的时间越早增产幅度越大。
Rice lodging during the grain-filling to milky-ripening stage not only increased the cost of harvesting, wasted labor, reduced the output, caused tremendous losses to the peasants, but also affected the quality of rice. In order to further explore the influence of rice lodging on rice yield and production efficiency, Rice quality, correct guidance for post-disaster self-help, since September 2007 a number of experiments on rice lodging Fuzheng, the test results show that after the rice lodging than righting non-Mu increase benefits significantly; and rice at the same time lodging at different times righting, with Fuzheng time postponed and production continued to decline, the right time to correct the greater the yield increase.
