| 摘 要： | 对横直深松、深松-浅耕和深耕3种不同耕作方式对砖红壤的孔隙度、圆锥指数、干密度和含水率的影响进行了试验研究,试验结果表明,横直深松更有利于提高砖红壤的孔隙度,增加土壤的透气性,降低土壤的圆锥指数,横直深松和深松-浅耕都能使土壤密度显著下降。数理统计分析表明,深松-浅耕、横直深松和深耕对含水率的影响有显著差异。深松能显著改善土壤的物理性质,有利于提高砖红壤的保水能力,是合理的耕作模式。

| Abstract: | Experiments were conducted to analyze the effect of different tillage treatments (including all-direction deep loosening, shallow tillage after deep loosening and conventional tillage) on the porosity, cone index, dry bulk density and moisture content of latosol. The results showed that all-direction deep loosening had more advantages to improve porosity and reduce cone index of latosol. Soil bulk density could be reduced obviously by tillage treatments of all-direction deep loosening and shallow tillage after deep loosening. The analysis of variance of the effect of tillage treatments on soil moisture content indicated that there was diversity of soil moisture content among all-direction deep loosening treatment, shallow tillage after deep loosening and conventional tillage. Deep loosening could obviously improve the water holding capacity. |
