| 摘 要： | 采用土壤盆栽试验方法,研究不同镁肥对不同土壤大豆(Glycine max(L.)Merrill)生长发育和养分吸收的影响。结果表明:施用硫酸镁和氧化镁肥对大豆植株地上部生长和养分吸收具有明显的影响,但对根系的影响相对较小。2种镁肥在不同土壤类型上的效果表现各异,在褐土和褐土性土上施用硫酸镁肥对植株地上部生长和养分吸收影响明显,而氧化镁肥在石灰性褐土上施用效果显著。研究结果表明,在合理施用氮、磷、钾肥基础上,在褐土和褐土性土上施用适量的硫酸镁或在石灰性褐土上施用适量的氧化镁对大豆植株生长和养分吸收都有明显的促进作用。

| Abstract: | A pot culture experiment was conducted to investigate the effects of different magnesium fertilizers on the growth,nutrient uptake of soybean(Glycine max(L.)Merrill)plants in different soil types.The experimental results showed that application of MgSO4 and MgO fertilizers had significant effects on growth and nutrient uptake of soybean plants in different soil types,whereas there was a small influence on roots.The plant growth and nutrient uptake of soybean were significantly influenced by MgSO4 fertilizer... |
