玉米高光效休耕轮作技术与农业资源土壤研究

Research on High Light-efficiency Fallow Rotation Technology of Maize Crop and Its Influence on Soil

本实验研究玉米高光效休耕轮作技术对土壤的影响,采用统计抽样测验分析方法,对比传统耕作及免耕农作方法下的土样进行分析。结果表明,玉米高光效休耕轮作技术使土壤容重降低,总孔隙度增加,土壤有机质较高,土壤蓄水保墒能力比传统垄作高,土壤养分得到了充分利用,同时减少了流失。在高光效休耕轮作技术之下,土壤容重降低,土壤水分含量较高,土壤养分得到合理利用,土壤资源得到了有效保护。实验证明,玉米高光效休耕轮作技术有效保护了土壤。

Soil from traditional and no-tillage farming practice was analyzed by statistical sampling test to study the impact of high light-efficiency fallow rotation technology of maize on soil. The results showed that high efficiency fallow rotation technology of corn reduced soil bulk density, but increased total porosity. Soil organic matter and soil water reservoir capacity were higher than conventional tillage. Soil nutrients could be fully utilized, while loses reduced. Soil resources were effectively protected under high light efficiency fallow rotation. Experimental results showed that high efficiency fallow rotation techniques of maize crop effectively protected the soil.
