With the devel ping f m dern inf rmati n techn l gy, the field inf rmati n c llecting techn l gy is devel ping and impr ving rapidly. Acc rding t several kinds f the field inf rmati n c llecting key techn l gies, including the GPS p siti ning techn l gy, the advanced sensing techn l gy, the multi-sens r inf rmati n fusi n techn l gy, the w ireless c mmunicati n techn l gy and s n, the research situati n f their applicati ns t the field p siti n inf rmati n, the s il attribute inf rmati n, the cr p gr w th inf rmati n, envir nment inf rmati n and cr p yield inf rmati n was discussed. T he advantages and disadvantages f the ab ve c llecting techn l gies w ere p inted ut respectively . Finally, the research directi n f the field inf rmati n c llecting techn l gy in the future is put f rw ard, which is devel ping the l w-c st, mult-i channel, high-precisi n and quick-p siti ning dynamic field inf rmati n digital intelligent measuring equipment w ith vari us advanced techn l gies.
