Technical Field

[0001] The utility model relates to a fertilization tool, in particular to a handheld fixed-point and quantitative fertilization device used for field fertilizer tests. Background Art

[0002] In the field of agricultural cultivation science research, field fertilizer tests are often needed to determine the effects of different factors, including fertilizer application amount, ratio, application period, etc., on crop growth. In actual operation, it is often necessary to add a fixed volume or weight of fertilizer to a fixed point. The general operation method is to weigh it manually or use a fixed volume container to hold it, pour it into the dug point, and then cover it with soil. This operation method has high labor costs, cumbersome process and low efficiency.

[0003] Existing fertilizer application equipment is generally large in size and is mainly used for applying fertilizer to fields with a slightly larger area. It is costly and relatively complicated to operate, and is not suitable for fixed-point and quantitative delivery of small amounts of fertilizer. Utility Model Content
