摘　　要：为优化甘蓝施肥量,确定其施肥分配比例以及施肥时期、施肥方法,在张家口坝上地区对甘蓝进行了滴灌施肥试验。结果表明,与传统施肥相比,配方施肥增加了甘蓝土壤硝态氮、速效磷、速效钾含量和电导率,可有效保持土壤的持续肥力;可溶性固形物与可溶性糖含量分别提高5.8%、48.6%,硝酸盐含量降低了39.0%,甘蓝品质得到显著提高;单位面积产量毛重、净重分别增加44730、37815 kg/hm^2,增幅分别为24.7%、29.9%,增产效果显著。In order to improve fertilizer use ratio on cabbage, understand fertilizer distribution proportion and fertilization time and method, fertilization experiment on cabbage under trickle irrigation was carried out in Bashang of Zhang Jiakou. The results showed that, compared with traditional fertilization, formulated fertilization could increase N, P, K content and electric conductivity in soil, and effectively maintain continuous soil fertility. Soluble solids and sugar content increased by 5.8% and 48.6%, respectively, the nitrate content reduced by 39.0%, and kale quality was improved significantly. The gross weight of yield per unit area and net weight increased by 44730 and 37815 kg/hm^2, and the growth was 24.7% and 29.9%,respectively, thus the yield increasing effect was significant.
