摘 要:[Objective] The aim was to select a cultivation method suitable for sandy lands in Liaoning Province. [Method] The research explored effects of autumn plowing, autumn rotary cultivation, autumn ridging, and rotary cultivation before spring sowing on physical and chemical properties. [Result] By autumn plowing, surface soils were seriously eroded, more water was evaporated, and more nutrients lost; by autumn rotary cultivation, surface soils were seriously eroded also, reducing wa- ter content and nutrients; by autumn ridging, surface soils were slightly eroded, so that evaporation was light and fewer nutrients lost; by rotary cultivation before spring sowing, soil erosion was the lightest, with more water and nutrients maintained. [Conclusion] It is effective for improving anti-wind erosion by no-tillage during fallow period and land reclamation before sowing in semi-dry areas.[目的]选择一种适合辽宁省风沙地的耕作措施。[方法]研究花生茬休闲期秋翻耕、秋旋耕、秋起垄、春播前旋耕4种耕作措施对土壤理化性状效应。[结果]秋翻耕地表土壤风蚀严重、水分蒸发量大、养分损失多,秋旋耕地表土壤风蚀较重、水分含量较低、养分损失最多,秋起垄地表土壤风蚀轻、水分蒸发量小、养分损失较小,春播前旋耕地表土壤风蚀最轻、墒情好、养分损失最小。[结论]风沙地花生茬休闲期采取播前旋耕是首选防蚀耕作措施。
