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.
