摘要: 【目的】研究施用氮磷钾对甘蓝产量和品质的影响及甘蓝的氮磷钾吸收特性。【方法】 以“苏甘25”为试验材料,采用“3414”部分实施方案,研究氮磷钾配比对甘蓝产量、品质、植株养分及土壤养分的影响。【结果】 氮磷钾配施后增加了甘蓝植株各部分鲜重、干重;增加了叶球VC含量,降低了硝酸盐含量;氮磷钾配施提高了植株各部分养分含量,改善了土壤养分。其中,处理E(N2P2K2)的产量最大、品质最优、植株及土壤养分相对较好。【结论】 综合考虑产量、品质、植株养分含量及土壤养分等指标,建议施N(300 kg/hm2)、P2O5(75 kg/hm2)、K2O(360 kg/hm2)是一种较好的氮磷钾配比,对甘蓝栽培有一定指导意义。

Abstract: 【Objective】Effects of NPK application on yield and quality of cabbage and NPK absorption of cabbage were studied.【Methods】The effects of NPK ratio on yield,quality,plant nutrient and soil nutrient of cabbage were studied with “sugan 25” as the experimental material and “3414” as the implementation plan.【Results】The fresh weight and dry weight of each part of cabbage were increased after NPK treatment.The content of VC was increased and the content of nitrate was decreased.Nitrogen,phosphorus and potassium fertilization increased the nutrient content of each part of the plant and improved the soil nutrient.Among them,treatment E(N2P2K2) has the highest yield,the best quality and relatively good plant and soil nutrients.【Conclusion】Considering the indexes of yield,quality,plant nutrient content and soil nutrient,N (300 kg/hm2),P2O5 (75 kg/hm2) and K2O (360 kg/hm2) are recommended to be a good ratio of NPK,which has certain guiding significance for cabbage cultivation.
