水稻机械插秧增苗减肥技术研究

摘要

Objective] The aim was to further improve rice production level and fertilizer utilization rate, reduce agricultural non-point source pollution, under the premise of not reducing the yield of rice, the input amount of chemical fertilizer was reduced.[ Method] Through simula-ting mechanical transplanting and field plot experiment, effects of seedling increasing and fertilizer reducing technology on rice yield were stud-ied.[ Result] Under the premise of increasing the basic seedlings and reducing chemical fertilizer dosage, the high yield structure can be es-tablished and the goal of increasing production can be achieved.[ Conclusion] The study can provide scientific and theoretical guidance for large area application of agricultural machinery transplanting.%[目的]进一步提高水稻生产技术水平和肥料利用率，减少农业面源污染，在水稻产量不降低的前提下，减少化学肥料的投入量。[方法]以模拟水稻机械插秧的方式，通过田间小区试验，研究水稻增苗减肥技术对产量的影响。[结果]在增加基本苗的前提下，适当减少化肥的用量完全可以建立高产的结构，达到增产、稳产的目的。[结论]该研究可为农业机械插秧大面积推广应用提供科学的理论指导。
