The method of wind erosion ring and pitfall tripping were used to observe the effect of strip width on the wind erosion modulus and verify the results received by field mobile wind tunnel.The wind erosion and wind-blown quantity were determined and the results showed that wind-blown quantity was decreased when the width was narrower than 6 m and increased with the increasing of strip width when the width was 6~10 m,and decreased when the width was wider than 10 m in the stubble of naked oat.The wind-blown q...
