摘要：

以木薯品种新选048为试材，进行不同地膜覆盖方式对土壤理化性状及木薯产量的影响试验，探讨木薯最佳的地膜覆盖方式。结果表明：地膜覆盖的土壤保水力、土壤孔隙度、土壤有机质、碱解氮、速效磷、速效钾含量木薯产都有比对照高，不同盖膜方式的增产效果不同。单行盖膜的效果最好，其次是双行盖膜。可见，木薯地膜覆盖栽培以单行盖膜方式，对改善土壤理化性状，促进木薯生长，提高木薯产量最有利。

Abstract:

The effects of the different film mulching on the physical and chemical properties of soil and the yield of cassava were studied in this experiment. The results showed that the soil moisture, total porosity, the contents of soil organic matter, available nitrogen, available phosphorus and available potassium and the yield of cassava with mulching film were higher than those of CK (without mulching film). The effects were different with different ways of mulching film. The effect of one-line mulching film was the best. The second was two-line mulching film.
