摘要
[目的]研究茎生叶和水稻生产相互关系。[方法]2014、2015年对江苏省农垦农业发展股份有限公司江心沙分公司水稻进行调查，分析水稻最长叶与植株性状、穗部性状、叶片总长度的相互关系，以及不同叶长序对水稻穗部性状的影响。[结果]倒2叶最长时穗下节和穗长较长、穗部性状较好；叶长序为213（45）时单穗重最高。[结论]生产上可通过相关措施促进倒2叶生长，构建合理的茎生叶叶长序来实现水稻高产。
Abstract
Objective] To research the correlation between cauline leaf and rice production.[Method] Rice in Jiangsu Provincial Agricultural Reclamation and Development Corporation was investigated in 2014 and 2015.We analyzed the correlation between rice longest leaf and plant traits and between panicle traits and total leaf length sequence.Effects of leaf length sequence on the rice panicle traits were researched.[Re-sult] When the 2nd leaf from top was the longest, internode length below the ear and ear length were relatively long and ear traits were relatively good.When leaf length sequence was 213(45), the spike weight was the greatest.[Conclusion] During production, related measures should be adopted to promote the growth of the 2nd leaf from top, to construct the rational length of cauline leaf, and to realize the high yield of rice.
