摘要
试验通过2014—2015年间,在吉林长春、辽宁铁岭、辽宁开原、内蒙古赤峰、宁夏银川、宁夏吴忠、新疆阿克苏、新疆乌鲁木齐8个地区种植秋光、隆69、粮10号、沈9903四个品种,对其产量及相关性状进行对比分析。结果表明,以新疆阿克苏、宁夏银川、宁夏吴忠和新疆乌鲁木齐为代表的西北地区较以内蒙古赤峰、吉林长春、辽宁开原和辽宁铁岭为代表的东北地区产量高;4个品种中以隆69产量最高;相关分析表明,粳稻产量与有效穗数呈显著正相关,因此,提高有效穗数是确保粳稻增产的关键。
The experiment was conducted in 2014 and 2015,eight planting regions were selected,including Changchun,Tieling and Kaiyuan,Chifeng,Yinchuan,Wuzhong,Aksu and Urumqi,the yield and yield component of 4 Japonica rice varieties including Qiuguang,Long 69,Liang10,and Shen 9903 in different region were compared and analyzed.The results showed that the north-west region represented by Aksu,Yinchuan,Wuzhong and Urumqi was higher in yield than the north-east region,which was represented by Chifeng,Changchun,Kaiyuan and Tieling.The yield of Long 69 was the highest in the 4 Japonica varieties.According to the correlation analysis,there was a significant positive correlation between the yield and the effective panicle number in Japonica Rice.Therefore,increasing the effective panicle number was the key point to increase the yield of Japonica rice.
