双季稻“三高一保”栽培技术

"Three High and One Ensuring" Cultivation Technique of Double Cropping Rice

根据我们多年研究成果,并与现在高产栽培成熟技术组装配套,集成了一套以提高成穗率、结实率、籽粒充实度和充分挖掘品种优质潜力(保优质)为主攻目标的双季稻"三高一保"栽培技术模式,并获国家发明专利。本文介绍了其技术原理和应用效果,并详细介绍了其核心技术和配套技术。核心技术包括育秧肥培育壮秧、"三控"结合控蘖,配套技术包括稀播细管、宽行浅栽、适肥促发、补肥防衰、增氧灌溉等技术。

According to our research results for many years, through assembling and matching the current mature high - yield- ing cultivation technology, we integrated a set of ＂three high and one ensuring＂ cultivation technique mode of double cropping rice, whose principal targets were to enhance panicle bearing tiller rate, seed setting rate and grain plumpness, and to fully dig the high - quality potential of rice variety （ensuring high quality）. This cultivation technique mode won the national invention patent. This pa- per introduced the technique principle and application effect of ＂three high and one ensuring＂ cultivation technique mode, and de- tailedly presented its core techniques and matching techniques. The core techniques included raising strong rice seedlings by apply- ing seedling - raising fertilizer, and controlling the ineffective tillers through the combination of water control, fertilizer control and chemical control. The matching techniques included sparse - seeding with fine management, wide row spacing with shallow plant- ing proper amount of fertilizer to promote early growth, supplementary fertilizer to prevent premature senescence, irrigation with ox- ygen increasing and so on.
