| 摘 要： | 研究比较5种不同覆盖物(薄膜覆盖,秸秆覆盖,1 cm、2 cm、3 cm生物材料覆盖)与裸地(CK)在每个季节3个不同土层深度(5、20、40 cm)的土壤温度。结果表明:5 cm土层(四个季节)以及20 cm土层(春季和夏季)的土壤温度,薄膜覆盖与裸地无明显差异,均明显高于秸秆覆盖,1 cm、2 cm和3 cm生物材料覆盖;40 cm(春季)、20 cm(秋季、冬季)和40 cm(秋季、冬季),5个处理的土壤温度与裸地无明显差异;40 cm(夏季),薄膜覆盖,1 cm、2 cm和3 cm生物材料覆盖,土壤温度与裸地无明显差异,均显著高于秸秆覆盖。

| Abstract: | This paper analysis the di fferences among five mulching methods ((plastic film mulch, straw mulch, 1 cm biological material mulch, 2 cm biological material mulch, 3 cm biological material mulch) and bare land with three different depth (5 cm, 20 cm, 40 cm) in every season. The results showed that plastic film mulch and bare land’ s soil temperature are not significantly different with 5 cm in every season and 20 cm in spring and summer. Moreover, they are higher than straw mulch, 1 cm, 2 cm and 3 cm biological material mulch.There is no significantly differences between five mulching methods and bare land with 40 cm in spring and 20 cm, 40 cm in winter and autumn. There is no significantly differences between Plastic film mulch, 1 cm, 2 cm and 3 cm biological material mulch and bare land with 40 cm in summer. They are higher than straw mulch. |
