通过对沿黄稻麦区稻作期间 57块典型田块的土壤渗漏速率测定 ,表明 59.6%的田块的土壤渗漏速率在 2 0～ 30mm/d ,约 30 %的田块渗漏速率过大 ,1 0 .5%的田块则因有障碍层而使土壤渗漏率过小。调查发现 ,施肥状况与土壤透水性有较密切关系 ,长期施用有机肥对土壤透水性能有改善效果。采用日产深松机深松 1～ 4次能有效打破 0～ 45cm土层内的紧实层或障碍层 ,减轻土壤紧实度 ,提高土壤渗漏速率。其中以深松 1次处理的产量最高 ,是既经济又有效的土壤透水性的改善措施 The soil leakage rate of 57 typical plots along the rice paddy region during rice cultivation showed that 59.6% of the plots had a soil leakage rate of 20-30 mm / d and about 30% of the field leakage rate Too large, 10.5% of the plots due to barrier layer so that the soil leakage rate is too small. The survey found that fertilization status and soil permeability are more closely related to the long-term application of organic fertilizer on the soil permeability improvement. The use of Nissan subsoiler pine 1 to 4 times can effectively break the 0-45cm layer of compaction or barrier layer, reduce soil compaction and increase soil leakage rate. Among them, the treatment of deep subsoiling is the highest, which is both an economical and effective measure to improve soil water permeability
