Abstract:

This study sought to determine the effects of different straw return patterns on the annual wheat-maize yield and soil organic carbon content (SOC) in the east area of Huang-Huai-Hai Plain. Four treatments were set up in the experiment: No straw return (NS), Summer maize-season straw return (SS), Winter wheat-season straw return (WS), and Double-season straw return (DS). SOC and aggregates classified by wet screening in 0-40 cm soil layers were measured. The straw return significantly decreased the soil bulk density and the mass proportion of micro-aggregate (< 0.25 mm), and increased the macro-aggregate of >5 mm, 5-2 mm, and 1-0.5 mm by 57.2%, 25.0%, and 13.7% on average suggesting straw return could accelerate soil aggregation and aggregate stability. MWD increased by 22.7%. Meanwhile, straw return not only increase SOC in 0-30 cm layers by 4.0% to 20.7%, and SCS by 0.2% to 14.7%, but also markedly increased the SOC of aggregates and carbon preservation capacity. The straw returning amount was correlated related with SOC, and SOC was positively correlated with MWD in 0-30 cm soil layers. In the 30-40 cm soil layer, both SOC of aggregates and carbon preservation capacity among treatments were not significantly different. The highest grain yield was observed in DS with the increased annual crop yield by 14.3%. Consequently, the double-season straw return model is a good option for improving soil quality in winter wheat-summer maize rotation systems; however, single-straw incorporation could maintain higher soil production, and provide abundant straw feed, energy and raw materials.

Key words: annual straw return model, aggregate, organic carbon, yield
