摘要
通过对早熟晚粳品种南粳5055机插高产超高产栽培技术集成的初步研究,结果表明:南粳5055茎秆粗壮、弹性好,抗倒性强。与常规栽培模式相比,高产超高产栽培中LAI和干物质积累量在抽穗期及成熟期较高。干物质积累量在拔节期至抽穗期和抽穗期至成熟期分别比常规栽培模式高。并探索了其产量及产量构成因素之间的相关关系,提出了相应的超高产栽培策略。
The high-yielding technical points of machine-transplanted seedling on the coefficient order of early late maturing japonica rice named Nanjing-5055 were made and the results indicated that it had stocky and elastic stem, strong lodging resistances. Compared with the general method, it can achieve higher LAI and dry matter accumulation in heading stage and maturity stage, dry matter accumulation were higher from jointing stage to heading stage and heading stage to maturity stage compared with the general method. At the same time it explored relevant relationships between yield and yield components, then came forward technology of the super high production cultivation.
