摘要
概述了湖南省近４０年来双季稻栽培技术发展的３个阶段：（１）６０年代初至７０年代中，以矮秆品种为主的“穗数型”栽培技术阶段；（２）７０年代中至８０年代末，以籼型杂交稻为主的“穗粒兼顾型”栽培技术阶段；（３）进入９０年代，以中秆大穗分蘖力中等的杂交稻为主的“穗重型”栽培技术阶段。还介绍了１０种有代表性的双季稻高产栽培技术，并对２１世纪的双季稻栽培技术的特点及研究内容进行了探讨。
his paper reviewed 40 years′ history of high yielding cultivation in double rice in
Hunan province and summaried as 3 development periods:(1) The period from the beginning of
60s′ to the middle of 70s′ is of the panicle number cultivation modle by using short plant
varieties;(2) The period from the middle of 70s′ to the and of 80s' is of both panicle number
and large panicle cultivation modle because of the extension of indinca hybrid rice;(3)The
period in 90s′ is of the weighty panicle cultivation modle because of the application of hybrid
rice with middle plant height, large panicle and middle tillering ablity. This paper also
introduced key points of 10 high yielding techniques of representation of double rice, and
discussed the study content and characteristics of double rice cultivation development facing to
21 century.
