摘要
吉林省水稻单产在年际间波动较大,造成单产不稳的原因是多方面的,气候波动是其主要原因之一。计算出吉林省20个县(市)水稻分蘖期温度、降水、日照3个因素的适宜度,根据试验结果将吉林省水稻适宜种植生态区划分为最适宜区、适宜区、次适宜区、不适宜区,从而为开发和利用吉林省水稻种植区的气候资源、水稻高产栽培提供科学依据。
The yearly yield of rice in Jilin province fluctuated a lot;and there were multiple reasons that causing the fluctuation,among which climate fluctuation was a main contributor.The suitable degree of temperature,rain and illumination during rice tillering stage in 30 counties（cities） in Jilin province was calculated.And the ecologic suitable rice planting region was divided in to most suitable region,suitable region,less suitable region and unsuitable region according to the results,thus providing a scientific reference for developing and utilization of climate resources in rice producing region in Jilin province and high yield rice cultivation.
