Abstract: In order to increase the content of soil organic matter, improve the quality of organic matter, provide theoretical basis and data support for the rational development and utilization of green manure resources in North China. Field trials were used to study the combined forms of humus, soil aggregate particle size distribution and stability of different spring Brassica campestris L. soils in North China through Shavinov classification and sodium pyrophosphate-sodium hydroxide extraction method. The test results showed that Spring Brassica campestris L.could increase the content of humus in soil combination and large aggregates, and increase the soil loose compact ratio, loose stable ratio, improve >5 mm particle diameter carbon enrichment coefficient, contribution rate of aggregates to soil organic matter compared with spring leisure. Among them, Zhongyoufei 1901 increased the most in soil loose-bound humus, stable-bound humus, compacted humus, which increased by 138.61%, 60.22%, 67.44% compared with spring leisure;Loose compact ratio was the largest increased in Zhongyoufei 1907, which increased by 43.94% compared with spring leisure; Loose stable ratio was the largest increased in Zhongyoufei 1901, which increased by 49.43% compared with spring leisure. The large aggregates contents of different spring Brassica campestris L.varieties was increased more in Zhongyoufei 1901 and Zhongyoufei 1907, which were significantly higher than other varieties;The carbon enrichment coefficient of >5 mm particle diameter was increased the most by Zhongyoufei 1901, and the contribution rate of soil organic matter was also best by Zhongyoufei 1901.

Key words: Spring Brassica campestris L., Soil aggregate, Humus-binding morphology, Contribution rate
