| 摘 要： | 目的]为超级稻机械插秧农艺方案配套提供了理论支撑。方法]采用复式裂区(再裂区)试验设计,研究3个因子(施氮量、移栽密度和每穴苗数)对不同类型超级稻品种吉粳88和吉粳102产量的影响。结果]对于耐肥型超级稻吉粳88,高产栽培要求较高的施肥、密度和每穴苗数。而对于广适型超级稻吉粳102,高产栽培的技术措施要求适宜的密度、每穴苗数和较少的施肥量。不同肥力条件下不同超级稻品种适宜的每穴苗数不同,低肥力和低密度下,增加每穴苗数可以通过增加每穴有效穗数而提高产量,但在较高的肥力和密度下,如果每穴苗数过高,可能因为群体质量恶化而降低产量。

| Abstract: | The objective of this study was sought theoretic support for mechanized transplant scheme of super rice.The split plot experiment was adopted to research the effect of three factors(fertilizer rate,transplanting density and seedling per hill) on the yield of'Jijing 88'and'Jijing 102'.Results showed that for fertilizer tolerance variety of'Jijing 88',high yield was gotten in higher fertilization,density and seedling per hill.For wide suitable variety of 'Jijing 102',high yield was gotten in suitable density,... |
