摘  要：
通过在油桐幼林中开展套种玉米、红薯和黄豆试验,并以纯油桐幼林为对照,研究油桐+玉米、油桐+红薯和油桐+黄豆套种模式对土壤的容重、比重、孔隙度等物理性质和全氮、全磷、全钾、水解氮、有效磷、速效钾、有机质和p H值等化学性质的影响。结果表明,油桐+玉米、油桐+红薯和油桐+黄豆套种模式均能改善土壤物理性质,也能显著提高油桐幼林土壤中全氮、全磷、全钾、水解性氮、有效磷、速效钾和有机质含量,分别比对照提高27.03%、40.50%、51.97%、57.03%、149.72%、109.34%和41.67%,油桐+红薯和油桐+黄豆模式对土壤理化性质影响优于油桐+玉米模式。

摘  要：
In this study, we investigated the effects of three intercropping patterns, Vernicia fordii+Maize, Vernicia fordii+Sweet potato, and Vernicia fordii+Soybean, on soil physical and chemical characters including soil bulk density, soil specific gravity, soil total porosity, total N, total P, total K, available N, available P, available K, organic matter, and p H value. The results showed that three intercropping patterns could improve soil physical characters. In comparison with the control, the intercropping patterns improved soil nutrient regime significantly. The total N, total P, total K and organic matter increased by 27.03%, 40.50%, 51.97%, and by 41.67%, respectively. The available N, P and K increased by 57.03%, 149.72% and 109.34%, respectively. The impact of Vernicia fordii+Maize and Vernicia fordii+Sweet potato intercropping patterns on soil physical and chemical characters was better than Vernicia fordii+Soybean inter cropping pattern.
