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
