2003年,长江中下游地区遭受夏季持续高温和秋旱等不利气象,导致单季晚稻结实粒数和粒重大幅下降而普遍减产。为研究防灾减灾技术,我们以松江区多年的单季晚稻定点考察结果和气象资料为材料,对2003年气象因素与单季晚稻生长发育的关系进行分析。
In 2003, the middle and lower reaches of the Yangtze River suffered from unfavorable weather such as the sustained high temperature in summer and autumn drought, which led to the general decrease of grain yield and grain weight in single season late rice. In order to study disaster prevention and mitigation technologies, we analyzed the relationship between meteorological factors and the growth and development of single-cropped late rice in 2003 with the data of single-season late-season fixed-point observations and meteorological data in Songjiang District.
