以杂交粳稻新组合“榆杂29”两年的超高产实践为研究内容,探讨该组合超高产的技术路线和主要的栽培技术措施.研究表明:1“榆杂29”的超高产技术路线有两条.2超高产需要肥沃的水稻土和科学的施肥、管理技术.3超高产的群体最大叶面积指数仍在孕穗期,达9.26~9.584超高产的关键措施:培育壮秧,适时早栽、施足促蘖肥,及时促控、增施钾肥、磷肥、保健栽培.5今后的超高产栽培主攻要点:提高结实率
Taking the super high yielding practice of hybrid rice “Yu-yu-29” for two years as the research content, the technical route and main cultivation techniques and measures of the super high-yielding combination were discussed. The research shows that: 1 “Yu-29” super-high-yield technology route has two. 2 Super-high yield needs fertile paddy soil and scientific fertilization and management techniques. 3 The maximum leaf area index of super-high-yield group is still at the booting stage, reaching 9.26 ~ 9.584 The key measures of super-high yield: Cultivate strong seedlings, timely early planting, enough to promote tillering, timely control and control, Phosphate, health cultivation. 5 future super high yield cultivation main points: to improve the rate of seed set
