| 摘 要： | 通过不同整地深度对土壤物理性质的影响研究,结果表明:深整地空白处的土壤含水率较对照空白处提高0.46个百分点;深整地较浅整地土壤垂直温度变化小,在0~70 cm范围内,每深10 cm,浅整地地温下降1.0 ℃,而深整地的下降0.9 ℃;深整地较一般整地土壤容重减小11%,土壤孔隙度增加5.5个百分点。研究结果还表明,适宜的整地深度以50~60 cm为宜,这有助于降低造林成本,提高经济效益。 |

| Abstract: | The effect of different depth of soil preparation on soil physical properties was studied in this paper.Water content of soil in blank space with deep soil preparation increased 0.46% than the contrasting blank space.Vertical temperature of soil with deep soil preparation changed little than that with shallow soil preparation.At the range of 0~70 cm,the earth temperature with shallow soil preparation decreased 1.0 ℃and that with deep soil preparation decreased 0.9 ℃ when the depth of soil added 10 cm.Volume weight of soil with deep soil preparation reduced 11% than general soil preparation.Soil porosity increased 5.5%.The optimal depth of soil preparation was 50~60 cm and it was conductive to minimize establishment costs. |
