The Relationship Between Root Traits and Yield Formation of Early-late Season Super Rice in South China
摘要
Abstract
In order to explore the relationship between root traits and yield formation of early-late season super rice in South China under Strong-source-live-sink ( SSLS ) and conventional high-yield ( CHY ) cultivation tech-nique. Effects of two cultivation techniques on root traits at different periods,yield and yield components of super rice(Liangyoupeijiu,Shengtai 1 hao,Yuxiangyouzhan,Guinongzhan,Hemeizhan and Fengmeizhan) were investiga-ted in field. The results showed that big yield difference of different varieties under the same cultivation condition, Liangyoupeijiu>Shengtai1hao >Yuxiangyouzhan,Guinongzhan >Hemeizhan,Fengmeizhan. The yield of the same rice under Strong-source-live-sink cultivation was higher than conventional high-yield cultivation,the yield of Lian-gyoupeijiu,Shengtai 1 hao,Yuxiangyouzhan,Guinongzhan,Hemeizhan and Fengmeizhan was 10. 06%,19. 74%, 21. 58%,23. 39%,18. 60%,26. 23% higher respectively compared with conventional high-yield cultivation. Root length,root surface area and root volume of the same rice under Strong-source-live-sink cultivation were higher than conventional high-yield cultivation. Root length,root surface area,root volume and root tip number were positively correlated with dry matter accumulation above ground,most significant in booting stage and filling stage. It is be-lieved that root traits and yield under Strong-source-living-sink cultivation were better than conventional high-yield cultivation,so Strong-source-living-sink cultivation was more suitable as corresponding cultivation technique of ear-ly-late season super rice in South China.关键词
