Study on Seedling Increasing and Fertilizer Reducing Technology in Machinery Transplanting

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.
