| 摘 要： | 玉米套种“堆作甘薯”能充分利用光能，并降低土壤容重、增加孔隙度和提高三相比中的气相容积，同时使土壤热容量、导热率和热扩散率降低，昼夜温差增大，因此能明显提高甘薯的产量和品质。

| Abstract: | This paper deals with the mechanism of increase in output of mound planting sweet potato interplanting with maize. By the interplanting the sun light energy can be fully used; the bulk density, the heat capacity, the heat conductivity and the temperature coefficient of Soil are reduced; and the porosity, the air Space ratio and the temperature fluctuation of soil are increased. These factors lead to increase in the porduction and quality of sweet Potato. |
