摘　　要：在总结双季超级稻栽培特性的基础上,提出了在适宜叶面积指数和库容量下,强化源和库的质量,即以适度密植,前期促早发低位大分蘖和叶面积指数快速增长,后期减缓叶片叶绿素含量的下降,强化叶片"源"的功能和籽粒"库"的活性而改良米质的"强源活库优米"栽培方法。分析了双季超级稻"强源活库优米"栽培的理论依据,介绍了以"超级稻壮秧剂"、"超级稻专用肥"和"超级稻米质改良剂"为核心物化技术、操作简便、省工、省力、高效、超高产的双季超级稻"强源活库优米"栽培技术。Based on the characteristics in cultivation of double-cropping super rice,a package of cultivation techniques of enhancing source,activating sink and improving grain quality（CTSSQ）was put forward,which is characterized by improving source and sink qualities under appropriate leaf area index（LAI）and sink capacity via suitable dense planting to achieve an early growth of lower tillers and a rapid LAI increase in early growing stages,alleviating decrease of chlorophyll content to strengthen functions of the source（leaves）and activity of the sink（grains）in late growing stages,resulting in an improvement in grain quality.The theoretic basis of CTSSQ was analyzed,and the CTSSQ for double-cropping super rice,which is a materialized-techniques-oriented technology including the use of ″a special seedling-strengthening agent（SSA）for super rice″,″a super rice specialized fertilizer（SSF）″ and ″a new super rice quality promoter（SRQP）″,was introduced in this article.It is found that CTSSQ is a super-high-yield cultivation system which is of high efficiency,labor-saving and easy to learn,accept and adopt by farmers.
