本试验评价了磷肥对孟加拉3种常见的农林树种,耳叶相思(Acacia auriculiformis)、含羞草(Albizia lebbeck)和黄豆树(Albizia procera)的苗木生长和根瘤菌固氮作用的影响。在苗床种植6个月苗龄的耳叶相思、含羞草和黄豆树与对照相比较磷肥对苗木生长和根瘤菌固氮作用的影响。结果表明:磷肥明显提高种苗的生长。对耳叶相思的生长有明显的促进作用,但对含羞草的生长影响不明显,在某种程度上降低了黄豆树的生长。研究也表明,磷肥明显提高植物的根瘤菌的大小与数量。

This experiment evaluated the effects of phosphate fertilizer on seedling growth and rhizobia nitrogen fixation of three common agroforestry species, Acacia auriculiformis, Albizia lebbeck and Albizia procera in Bangladesh. Effects of Phosphates on Seedling Growth and Rhizobium Nitrogen Fixation of Acacia auriculifolium, Mimosa and Soybean Trees in Seedling Bed with 6-Month-Old Seedlings. The results showed that: phosphorus fertilizer significantly increased seedling growth. On the growth of Acacia aureus significantly promote the role, but the growth of mimosa no significant effect, to some extent, reduce the growth of soybean. Research also shows that phosphate fertilizer significantly increases the size and amount of rhizobia in plants.
