摘　　要：根据四川盆地的气候特点和两熟制稻区杂交水稻生产实际，研究出了一套以“秧田超稀植培育超多蘖壮秧”和“大幅度减少本田栽插穴数”为技术核心的“杂交中稻超多蘖壮秧超稀植栽培”新模式。研究和生产实践表明，该模式能进一步发挥杂交水稻的高产潜力，同时可以省种、省工、降低生产成本。越稀栽培杂交稻高产的基本原理在于具有比常规多穴栽培更良好的秧苗质量，更合理的田间群体结构，更突出的单茎生长优势，更发达、更具活力的根系和更优良的穗部性状。The research and production practices showed that the new method of super-multiple-tiller seedlings transplanting plus super-thin spacing or SMTST-STS can not only further increase the productivity of mid-maturing hybrid rice,but also save seeds, labor and costs, The principles for high yield with SMTST-STS lies in that, compared with conventional dense-spacing method,the new method brought out better seedlings,better field group struc-ture, more dominant individual superiority, more developed root systems with higher vitality and better spike characters.
