Abstract: 【Objective】 In order to optimize the amount of nitrogen fertilizer used in pepper planting and explore the rational use of nitrogen fertilizer, the tests on yield and quality of pepper were carried out in Chengguan Township of Yengisar of Xinjiang, China.【Method】 Two experiments: conventional fertilization and optimal fertilization were used to compare the two treatments, and the nitrogen fertilizer addition gradient analysis was carried out in the experiment. Among them, conventional fertilization was used by most local farmers in production, while the optimized fertilization technique was the one obtained recently for reaching high yield, high efficiency or high quality for their corresponding crops. The purpose was to illustrate the effect of optimizing fertilization nitrogen element on increasing the yield of pepper by comparing the two.【Result】 The results showed that compared with the conventional fertilization area, the average yield of pepper was 3,153.6 kg in the optimized fertilization area and 2,233.5 kg in the conventional fertilization area, and the yield in the optimized fertilization area was 17.8 kg higher than that in the conventional fertilization area.【Conclusion】 The results showed that through the analysis of the results of this experiment, it is proved that nitrogen fertilizer can increase the yield of pepper, and the scientific and reasonable fertilization method should be adopted when applying nitrogen fertilizer in production, so as to provide scientific basis for high yield, economy and environmental protection fertilization.

摘要： 【目的】分析合理使用氮肥,优化氮肥在辣椒种植中的使用量,为高产、经济、环保施肥提供科学依据。【方法】以常规施肥和优化施肥2个处理进行对比,并对优化施肥处理实验进行氮肥添加量梯度分析。其中常规施肥是在生产中习惯采用的施肥技术,优化施肥为当地近期获得的相应作物高产高效或优质高产施肥技术,比较两种技术优化施肥氮元素对辣椒增产效果。【结果】优化施肥区与常规施肥区相比较,优化施肥区辣椒平均产量为3 153.6 kg/667 m²,常规施肥区平均产量2 233.5 kg/667 m²,优化施肥区比常规施肥667 m²增产17.8%。【结论】氮肥在辣椒种植上增产作用,在生产上促进在施用氮肥时要采用科学、合理的施肥方法。
