甘蔗花生间作体系中红壤地根际pH值与有效磷含量的关系
|
摘要
为了探讨甘蔗花生间作中红壤蔗地根际土壤有效磷含量与pH值的关系,本研究进行了田间试验。试验设置了甘蔗单作、花生单作和甘蔗/花生间作3个种植处理,在甘蔗、花生不同生育期采样分析土壤有效磷和根际pH值。结果表明:与单作处理相比,甘蔗/花生间作能显著增加了作物根际土壤有效磷含量,却降低了根际土壤pH值。相关分析结果显示,甘蔗和花生根际土壤有效磷含量与根际pH值之间存在着显著的负相关关系。试验说明,在红壤上甘蔗/花生间作根际土壤的酸化是促进土壤磷有效性增加的原因之一。
A field trial was conducted to investigate the relationship between available phosphorus content and pH in rhizosphere of red soil in sugarcane and peanut intercropping system. Three planting treatments,sugarcane monocropping,peanut monocropping,sugar/peanut intercropping,were designed for the experiment,and soil samples were taken from rhizosphere soil at different growth stages of sugarcane and peanut. The results showed that,compared with the monocropping treatments,sugarcane and peanut intercropping increased the content of soil available phosphorus while decreased the p H in the rhizosphere of sugarcane and peanut. Correlation analysis showed that there was a significant negative correlation between the available phosphorus and pH in the rhizosphere soils,which indicated that the acidification of rhizosphere soil in the sugarcane and peanuts intercropping system should be one of the important reasons for increasing the availability of phosphorus in red soil.
