摘要
通过红壤上石灰石粉与磷肥配施对盆栽大豆生长和养分吸收影响的研究表明,施石灰石粉、钙镁磷肥均能提高土壤pH,显著增加大豆的产量,提高其养分的转运率;施石灰石粉能提高植株含钙量,却抑制了对钾的吸收,施磷肥提高植株含磷量,但降低植株含钙量。
A pot experiment was carried out to determine effects of limestone application with phosphate on growth and nutrient absorption of soybean on red soil. It was shown that limestone application with phosphate increased soybean yield on red soil and improved the rates of nutrient transformation in soybean plants. Liming markedly increased Ca content but decreased K content in soybean plants. Phoshate application markedly raised P concentration in soybean plants. Limestone application with phosphate decreased soil acidity.
