[目的]研究配施硼肥条件下不同氮肥处理水平、优化施肥和常规习惯施肥对甘蓝产量和品质的影响.[方法]设无氮区、70％优化施氮区、优化施氮区、130％优化施氮区、优化施氮无硼区,随机排列.同时,取样测定甘蓝硝酸盐、VC、还原糖、氨基酸含量等品质指标.[结果]与习惯施肥相比,各施肥处理显著提高甘蓝产量,增产幅度为3.86％～12.98％,以优化施氮处理的增产幅度最大.各施肥处理均降低甘蓝的硝酸盐含量,降幅为1.9％ ～29.7％,其中降幅最大的是无氮处理,其次是优化施肥处理.各处理对甘蓝营养品质的影响不一致,均降低了甘蓝的VC含量；仅无氮处理提高甘蓝还原糖含量8.4％;130％优化施氮处理和优化施氮缺硼处理分别增加甘蓝氨基酸含量2.7％和8.3％,其余处理均不同程度地降低甘蓝氨基酸含量.[结论]各施肥处理显著提高甘蓝产量,降低硝酸盐含量.各处理对甘蓝营养品质的影响不一致.%[ Objective ] A field experiment was conducted to study the effects of different N combination of B with optimized and convention fertilize on yield and quality of cabbage. [ Method] There were 5 different treatments without nitrogen, 70% optimized nitrogen fertilizer, optimized nitrogen fertilizer, 130% optimized nitrogen fertilizer and optimization of nitrogen fertilizer boron deficiency. The experiment was arranged randomly. Meanwhile nitrate vitamin C, soluble sugar and amino acid of the qualities index were determined. [Result] The different treatment could increase the yield of cabbage by 3. 86% - 12.98% significantly. The highest yield was the treatment of optimize nitrogen fertilizer. Compared with the convention measure, nitrate content of cabbage was decreased by 1.9% -29.7% , the lowest was without nitrogen treatment and the second treatment was optimized fertilizer. It was inconformity for the quality of cabbage by different treatments. The contents of vitamin C was reduced with all the treatments. Only without nitrogen treatments soluble sugar improved 8.4%. The treatment of 130% optimized nitrogen fertilizer and optimization of nitrogen fertilizer boron deficiency enhanced amino acid content by 2.7% and 8.3% of cabbage. The others decreased the content of amino acid differently. [ Conclusion] All the treatments could increase the yield of cabbage and decrease the content of amino acid significantly. The change of cabbage nutrition quality was different in fertilization treatments.
