Abstract: The study aimed to investigate the application of soil testing and formulated fertilization technology in mechanical-transplanted late rice. Typical large-scale planted high-yielding fields and low-yielding fields were selected as the study sites. The formulated fertilization plan was made according to the soil fertility, seedling quality and weather conditions. The results indicated that, through soil testing and formulated fertilizing, the total amount of N fertilizer, fertilizer types and the fertilization ways were optimized, which can achieved the goal of cost saving, production and efficiency increasing. This fertilizing pattern showed great application value in rice production.

Key words: Yongyou 9, late mechanical transplanting rice, soil testing and formulated fertilization technology

摘要： 以连作晚稻为研究对象，选取规模种植大户典型的高产田和低产田为试验点，通过土壤理化性质化验，制定肥料运筹方案，开展了配方施肥与常规施肥对比试验，探讨配方施肥技术在机插连作晚稻上的应用效果。结果表明，不同类型的连作晚稻机插田，通过测土配方施肥，调整氮肥总量，利用尿素等速效肥代替复合肥作追肥，增施穗肥，可以达到节本、增产、增效的目的，在生产上有应用价值。
