| 摘 要： | 通过多年试验研究,形成了一套水稻高成穗率、高结实率、高籽粒充实度和保优质为核心的双季稻"三高一保"栽培技术模式。本文通过田间试验和多点应用示范,比较研究了双季"稻三高一保"栽培技术模式的效果。田间试验表明,"三高一保"栽培技术模式能促进前期早发、控制无效分蘖发生,促进有效分蘖生长和成穗,提高成穗率,增加总颖花数、提高结实率和籽粒充实度,极显著地增加水稻产量,增产幅度为12.22%～19.73%,并能改善米质。大田示范结果表明也验证了田间试验的结果。

| Abstract: | A set of "three high and one ensuring" cultivation mode of double cropping rice, the core of which was high panicle bearing tiller rate, high seed setting rate, high grain plumpness and ensuring high quality, was explored through many years of research. In this study, the effect of "three high and one ensuring" cultivation mode of double cropping rice was compared and investigated by field experiment and multiple location demonstration. The field experiment indicated that "three high and one ensuring" cultivation mode promoted the vegetative growth during early stage, inhibited the formation of ineffective tillers, promoted the growth of effective tillers and the formation of panicles, improved the panicle bearing tiller rate, increased the total number of spikelets, enhanced the seed setting rate and grain plumpness, increased the grain yield by 12.22%-19.73% at highly significant level, and improved the rice quality. Furthermore, the field demonstration also verified the results of field experiment. |
