Abstract: In order to study the effects of different treatments on yield, yield components and quality of soybean, this experiment took ‘Chengdou 6’ as material, and setup treatments with different sites, fertilization levels and planting density. The results showed that suitable fertilization levels for Yu County of Zhangjiakou, Funing County of Qinhuangdao, Pingquan District of Chengde were urea (149.6 kg/hm2), bisamine (180 kg/hm2) and muriate potash (149.6 kg/hm2), and when the optimal planting density was 195 000 plant/hm2, the yield could be the highest. The basic soil fertility and climatic conditions of different testing sites were compared and found that Pingquan District had higher contents of alkali-hydrolyzable nitrogen and rapidly available potassium than the other 2 sites. Even if under the low contents of rapidly available phosphorus and organic matter, it was still a suitable testing area for high yield of ‘Chengdou 6’. Its fat content was the highest, but protein content was lower. This paper screened suitable fertilization level and planting density for soybeans growing in different testing areas, and explored suitable high yielding and high efficient soyabean cultivation technology through significant analysis on yield, yield components and quality of soybean grown in the mountainous area of northern Hebei Province.

Key words: mountainous area, soybean, fertilization level, planting density

摘要： 以承豆6号为试验材料，设置不同地点、施肥水平与种植密度的处理，研究不同处理对大豆产量及产量构成和品质的影响。结果表明，张家口蔚县、秦皇岛抚宁、承德平泉地区适宜的施肥水平尿素、二胺、氯化钾达到149.6 kg/hm2 、180 kg/hm2、149.6 kg/hm2,适宜的种植密度为19.5万株/hm2 时产量最高。比较不同试验点的基本地力和气候条件，承德平泉地区与其他两地比较具有较高的碱解氮和速效钾，即使在速效磷和有机质含量偏低的情况下，仍然是承豆6号高产的适宜试验区，其脂肪含量最高，蛋白质含量最低。筛选了不同试验区大豆的适宜施肥水平和种植密度，通过对产量及产量构成和品质的显著性分析，探索出河北省北部山区大豆适宜的丰产高效栽培技术。
