9. plant soil moisture alarm method according to claim 8 is it is characterised in that described step S3 is specially：
S3a) data analysis unit is according to the water content receiving data and being calculated soil, and judges whether this water content is less than
Default soil moisture content lower limit, if it is, execution step S3b；
S3b) control alarm unit to be reported to the police, and calculate volume V that soil moisture need to feed, inject in corresponding deposit box
The section S of pipe and flow velocity L, is calculated the deposit box valve opening time T, wherein T=V/ (S × L) needing supply；
S3c) control unit controls corresponding deposit box valve opening, and the time arrival storage opening deposit box valve is being detected
Store case valve opening time T, close corresponding deposit box valve.
10. plant soil moisture alarm method according to claim 9 is it is characterised in that further comprising the steps of：
S3d) data analysis unit is additionally operable to the data that real-time reception is derived from Soil K+adsorption module, and it is current to be calculated soil
Water content, when the current water content of soil is equal to the default soil moisture content upper limit, data analysis unit passes through control unit
Close corresponding deposit box valve.
