【摘要】In order to determine the waterlogging tolerance ability of rice at tillering stage, taking normal rice variety Xiangzaoxian45 as experimental material to conduct waterlogging stress experiment which designed with different waterlogging depths and waterlogging lasting time at tillering stage. Through observed the changes in number of green leaves, plant height, stem number, growth period, yield structure, the results indicated that for changes in number of green leaves, if the rice was at the same growth period and with the same waterlogging depth, it negatively correlated with waterlogging time, if the rice was at the same growth period but with the different waterlogging depths, it was more obvious in treatment with 2/3 depth of waterlogging in comparison with treatment with complete waterlogging; for changes in plant height, if the rice at the same growth period but with different waterlogging depths, it was more obvious in treatment with complete waterlogging in comparison with treatment with 2/3 depth of waterlogging; for changes in stem, if rice was at the same period but with different waterlogging depths, the tillering rate at high position in treatment with complete waterlogging was higher than that in
