4个粳稻品种在不同种植区的产量和产量构成因素分析
Analysis of Yield and Yield Component of 4 Kinds Japonica Rice Varieties in Different Region
摘要
Abstract
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 Qi-uguang, 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 cor-relation 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.关键词
