【摘要】 [目的]研究芝麻高产高效的平衡施肥技术。[方法]采用田间试验研究平衡施肥对芝麻生长和产量的影响。[结果]结果表明,最佳氮磷钾处理较不施氮肥的对照增产24.5%,施磷产量相对提高5.8%,施钾增产12.3%,较不施肥的空白对照产量增长31.5%;施硼增产率为9.0%。每公顷增收542~2 374元,施肥产投比为(1.46~22.23)∶1。[结论]氮磷钾硼配合施用的平衡施肥对夏芝麻生长发育具有良好的促进作用。更多还原

【Abstract】 [Objective]The research aimed to study the balanced fertilization for high-yield and high-efficiency cultivation of sesame.[Method]Field trial was conducted to study the effects of balanced fertilization on sesame growth and yield.[Result]The results showed that,sesame yield under the optimum NPK treatment increased by 24.5%,5.8%,12.3% and 31.5% compared with that omitting nitrogen,phosphorus,potassium and NPK,and 9.0% increase compared with NPKB treatment.The profit improved by 542-2 374 yuan/hm2 with the value cost ratio(1.46-22.23)∶1.[Conclusion]There was a remarkable yield response of sesame to balanced fertilization.更多还原
