摘　　要：在极端高温天气下,对大面积杂交中籼稻生长情况进行跟踪调查。调查结果表明,当前水稻生产中杂交中籼品种抗高温能力较强;不同杂交中籼品种抗高温能力有差异;在一定范围内,播期越早,极端高温天气对杂交中籼稻产量影响越大。The growth characteristics of indica hybrid rice in the large area were investigated under the extreme high temperatures. The results showed that the varieties of indica hybrid rice have strong resistance to high temperature in current rice production; different varieties of indica hybrid have different ability of resistance to high temperature; in a certain range, the sowing time is earlier, the influence of extreme hot weather on the yield of indica hybrid rice would be bigger.
