摘要
通过机插稻氮肥不同施肥量,前后期不同比例施肥,分蘖肥和穗肥施用时期等试验,揭示了机插水稻高产栽培中氮肥的最适用量,分蘖肥和穗肥最适试用时期,基蘖肥和穗肥的最佳比例等技术关键。明确机插稻在实行群体质量栽培时,应采用"前控、中稳、后增"的施肥技术,其运筹要点为少施基肥、施足促蘖肥、增施穗肥。
The experiment was conducted to study N fertilization amount, N fertilizer application ratio at early and late stages and application time of tiller fertilizer and panicle fertilizer. The key N application techniques were put forward in aspects of optimum application amount, the suitable application time of tiller fertilizer and panicle fertilizer, the best ratio of basal-tiller fertilizer and panicle fertilizer. In mechanical transplanting cultivation aiming at population quality, the N fertilization technique, ＂early control, middle stabilizing and late emphasis＂, that is, less basal fertilization, moderate tiller fertilization and more panicle fertilization should be applied.
