| 摘 要： | 日光温室空闲期，采用宽8m厚0.08mm普通PE塑料薄膜覆盖土壤，密闭温室进行高温闷棚，5cm土壤日均地温达到42.1℃，≥40℃的时数13.87h，其中≥45℃的时数7.82h；20cm土壤日均地温39.7℃，≥40℃的时数达11.90h。5cm土壤温度达到了真菌致死的范围，20cm土壤温度可使土壤中的真菌数量显著减少，有效地防治温室蔬菜土传病害的发生。

Study on the Solar heating for soil pasteurization in greenhouse |
| |
| Abstract: | ：Moistened soils in greenhouse were mulched with transparent 0.08mm PE film in July and August, and soil temperatures were thereby increased. The average soil temperatures reached 42.1℃ and 39.7℃ at the depth of 5 and 20cm respectively. ≥40℃ accumulated hours reached 13.87h and 11.90h at the depth of 5 and 20cm respectively. ≥45℃ accumulated hours reached 7.82h at the depth of 5cm. The temperatures at the depth of 5cm are lethal to the pathogens, and the temperatures at the depth of 20cm are efficient to reduce the population of pathogens. |
