Research on the Effect of Bacterial Manure on Poplar Growth

The result of the potted experiment shows that,compared with the control and those fertilized with peat,the Populus×xiaozhuanica W.Y.Hsu et Liang seedlings inoculated with bacterial manure are significantly different in the height of the seedlings,the diameter at ground;the number of the leaves,the size of the leaf,etc..Besides,the fiber length of the stem and the nutrient elements in it are both increased obviously.The soil nutrent content is replenished to some extent instead of getting lost.So the soil fertility is well preserved.The result of field afforestation experiment also shows that populus euramericana CL“Bellinii” inoculated with bacterial manure are different obviously with the control and those fertilized with a Ca3(Po4)2 in the height and the diameter at breast height ( DBH ).
