摘  要：
在玉米沟垄集雨种植模式下对沟内覆盖普通地膜、生物降解膜、液体地膜及秸秆的耕层土壤温度及玉米出苗状况进行了观测。两年结果表明,普通地膜和生物降解膜覆盖均能显著提高土壤温度,在5~25 cm耕层平均温度比不覆盖分别增加2.51℃~3.77℃和1.30℃~2.19℃,液体地膜覆盖与对照差异很小,增温值为0.13℃~0.56℃,而秸秆覆盖与不覆盖相比有明显的降温作用,其5~25 cm土层温度比对照降低1.25℃~2.19℃。普通地膜和生物降解膜覆盖分别使玉米提前4 d和3 d出苗,秸秆覆盖使出苗期推迟2 d,液体地膜覆盖与对照的出苗期无差异。

摘  要：
Effects of common plastic film,biodegradable film,liquid film and straw mulching on tilth soil temperature and maize emergence were observed under planting pattern of ridge and ditch.Two-year results showed that common plastic film and biodegradable film mulching could improve significantly the soil temperature.The average temperature in 5～25 cm tilth soil under common plastic film and biodegradable film mulching were 2.51℃～3.77℃ and 1.30℃～2.19℃,respectively, which is higher than that of the uncovered ground.The difference between the liquid mulching and control is very little with the warming value of 0.13℃～0.56℃.Straw mulching could reduce soil temperature,and the tilth soil temperature were 1.25℃～2.19℃ which is lower than that of the control.Maize emergence were promoted 2 d and 1 d earlier under common plastic film and biodegradable film mulching,respectively,but was delayed 1d under straw mulching,and showed no difference under liquid film mulching as compared with the control.
