| Abstract: |
| 【Objective】To investigate the effects of different colors of mulch film and drip irrigation soil wetted percentage on soil temperature, soil moisture content, sweet potato growth and development, yield and quality, and to provide a theoretical basis for sweet potato cultivation in Rizhao, Shandong Province. 【Method】The field experiment was conducted with three different mulch treatments: black film (BM), transparent film (TM) and no film (NM). Three drip irrigation soil wetted percentage treatments were set up: no irrigation (P0), 30% wetting ratio (P1), and 60% wetting ratio (P2), for a total of nine treatments. 【Result】The results showed that the mulch treatment could significantly increase the soil temperature of sweet potato in the early stage under the same soil wetted percentages conditions, and the soil temperature change of P2 treatment was less than that of P1 treatment and P0 treatment under the same mulch conditions. TM treatment could increase the soil moisture content in the early stage of fertility, and mulch could increase the surface runoff and reduce the soil water content in the rainy season. Under the same soil wetted percentages condition, BM treatment yielded higher than NM and TM treatments, and P1 treatment had the highest yield under the same mulching condition. Mulching and drip irrigation wetness ratio could significantly affect the stem thickness and vine length of sweet potato. Mulching could significantly increase the root dry matter quality and aboveground dry matter quality of sweet potato. The BM treatment had the most significant effect on sweet potato yield. 【Conclusion】The yield of BMP1 treatment is the highest under the conditions of this experiment. |
