摘　　要：【目的】为了突破水稻生产存在施氮量多施钾量少、化学防治用药量多农艺调控措施少以及大水漫灌、栽培管理不到位等瓶颈,实现节本增效提供参考。【方法】早、晚稻分别选择相邻的2块田,每块田分为左右两半,左边为＂对照＂,右边为＂三控＂进行试验;定期调查群体分蘖动态和生育进程,病虫害发生和倒伏情况;成熟期取样考种,实割计产。【结果】水稻＂三控＂施肥禾苗生长平稳、植株健壮,后期青枝蜡杆,病虫发生较轻。与对照相比,早、晚稻667m2增产42.75kg和35.8kg,增8.6%和7.6%;每667m2人工投入少1工人以上,化肥成本降低约73.8元,病虫害防治少1-2次以上,农药投入少21.0元,667m2节本增收入163.6-171.3元。【结论】在相同或适当降低肥料投入情况下,＂三控＂施肥禾苗生长平稳、植株健壮,后期青枝蜡杆,病虫害发生减轻,病虫害防治减少1-2次以上,农药投入减少（节省农药21.0元/667m2）,早、晚稻增产增收效果显著。【Objective】In order to provide the reference for the paddy rice cultivation of cost- saving synergies.【Method】Conducted field contrast test,selecting adjacent two field blocks respectively for early and late rice,each field is divided into two half, the left side as the ＂control＂, the right to ＂three control＂ test;【Results】The test results show that, compare with the control, the right side paddy rice cultivation which applying ＂three control＂ method（the control of rice seedlings, control fertilizer, control diseases and pest） with the follows advantages： crops growth stable, robust plants, green stick wax rod in late period, less diseases and insect pests happening. 【Conclusion】Under the condition of applying same or reduced fertilizer inputs, the early and late paddy rice cultivation with ＂three control＂ method with the follows advantages：growth well, healthy, green stick wax rod in late period, less diseases and insect pests happening, which achieve the obvious effect of pesticide saving, increasing both production and income.
