辽宁省水稻小面积超高产栽培技术经验分析

Primary Study on the Experience of Rice Super High Yielding Cultivation Technology in Small Area in Liaoning Province

水稻超高产栽培是目前国内外稻作研究的一个热点，作者参与了辽宁省１９８８年至１９９１年水稻“丰收杯”竞赛和１９９０年至１９９２年“辽河流域水稻高产高效益配套技术开发研究”工作，对产量超过１０５００ｋｇ／ｈａ的超高产田的栽培技术经验进行了调查与研究，分析了超高产的原因，总结了超高产的经验。

Studying the rice super high yielding cultivation is a hot spot in home and abroad.The authors participated the work of“The Bumper Harvest Cup” competition in 1988 1991 and“The High Yield and High Efficiency Integrated Technology Exploitation and Research in Liaohe River Delta” in1990 1992.Some investigation and research have been conducted on the super high yielding fields with yield over 10500kg/ha,and reasons of super high yield have been analyzed and the experiences have been summarized.
