Claim 4:
5. The system according to claim 3, wherein the obtaining the soil moisture content and the plant status parameter of the grid area with no sampling point according to the soil moisture contents and the plant status parameters at the plurality of sampling points adjacent to the grid area with no sampling point comprises:
selecting any point as an origin;
obtaining location vectors of adjacent ones of the plurality of sampling points according to the origin and locations of the plurality of sampling points adjacent to the grid area with no sampling point;
obtaining a location vector of the center point of the grid area with no sampling point according to the origin and a location of the center point of the grid area with no sampling point;
assigning weight coefficients to the location vectors of the adjacent ones of the plurality of sampling points such that a weighted vector sum of the location vectors of the adjacent ones of the plurality of sampling points is equal to the location vector of the center point of the grid area with no sampling point; and
weighting and accumulating the soil moisture contents and the plant status parameters at the adjacent ones of the plurality of sampling points according to the weight coefficients to obtain the soil moisture content and the plant status parameter of the grid area with no sampling point.
