[0091] Specifically, Figure 4 A flow chart of determining problematic soil nutrients in the method provided by an embodiment of the present invention is shown.

[0092] Among them, in the preferred embodiment provided by the present invention, the determining of problematic soil nutrients corresponding to the plurality of problematic planting sub-regions specifically comprises the following steps:
