摘  要：
[目的]研究早稻分蘖到抽穗期地上部分生长率和净生物积累量受气象因子影响的规律。[方法]利用数理统计方法分析江西省农业气象试验站1995~2006年早稻从分蘖到抽穗期的气象环境因子与早稻生长率及净生物量积累之间的关系。[结果]结果表明:分蘖到拔节期的生长率与温度因子呈正相关,平均最高气温、日平均气温每上升1℃,生长率分别增加2.56 g/(m2.d)和2.73g/(m2.d),平均温度日较差每增加1℃,生长率就增加3.0 g/(m2.d);拔节到抽穗期生长率与降水量和相对湿度呈负相关,相对湿度每增加1%,生长率就降低0.7 g/(m2.d)。分蘖普遍期到抽穗普遍期净生物增长量与平均温度日较差呈正相关,达极显著水平,日较差每增加1℃,净生物量干重增加33.1g/m2。[结论]随着气候变暖,早稻播期、移栽期发生变化,不同品种的适应性也不同。

摘  要：
[Objective]The research aimed to study the effects of meteorological factor on early rice overground part growth rate and net biomass from tillering stage to digestibility stage.[Method]The relationship between early rice growth and meteorological environment factor from tillering stage to digestibility stage in Nanchang from 1995 to 2006 was analyzed using mathematical statistic method.[Result]From the tillering prevalence stage to the jointing stage,the growth rate and temperature factor showed positive correlation,the growth rate of early rice increased 2.56 g/(m2·d)and 2.73 g/(m2·d)respectively as the average maximum temperature rising at the speed of 1 ℃.The growth rate increased by 3.0g/(m2·d)as the average diurnal temperature range rising at the speed of 1 ℃.From jointing to the spiking stage,precipitation and humidity showed negative correlation,the relative humidity increased by 1%,the growth rate would reduce at the speed of 0.7 g/(m2·d).Net amount of dry matter of early rice was positively correlated to the average diurnal temperature range,and reached a significant level.When diurnal range increased 1 ℃,the net amount of dry matter would increase by 33.1 g/m2.[Conclusion]Sowing date and transplanting stage changed as the warming of climate,and different varieties had different adaptability.
