Technical Field

The utility model belongs to the technical field of fertilizer injection unit, specificly provide a fertilizer applicator.

Background

In agricultural production, in order to improve the yield and the quality of fruit trees, the fertilizer needs to be applied in time according to the growth condition of the fruit trees. Before fertilization, a fertilizing ditch with the depth of 20-40cm is dug around a fruit tree, fertilizer is put into a pit, and then soil is covered. Compared with the mode of directly applying the fertilizer to the ground surface, the mode of ditching and fertilizing has the advantages that the fertilizer cannot volatilize due to being dried, the absorption of fruit trees is facilitated, the fertilizer consumption is reduced, and the utilization rate of the fertilizer is improved. However, the fruit trees need to be fertilized for 2 to 3 times every year, namely, ditching for 2 to 3 times, the operation is complicated, the labor cost is high, the water and soil loss is easily caused by repeatedly digging soil, and in addition, the tree roots are easily damaged.

In recent years, some fertilizer applicators of a pre-buried type have been used, but these fertilizer applicators are used only for applying liquid fertilizer, and the holes of the fertilizer applicators pre-buried in the soil are easily clogged.
