Environment signal optimal sparse sampling method suitable for agriculture

The invention relates to the technical field of agricultural environment signal acquisition, and discloses an environment signal optimal sparse sampling method suitable for agriculture, which specifically comprises the following steps: S1, erecting a plurality of support columns in a field, the distance between every two adjacent support columns being 30m; and sequentially fixing different types of sensors a1, a2, a3 and a4 on the plurality of supporting columns from top to bottom. According to the invention, a plurality of groups of supporting columns with sensors are erected in the field, sothat the problem of inaccurate acquisition indexes caused by terrain and climate influence can be solved, the current agricultural environment signal can be averagely sampled by adopting an optimal sparse sampling mode, the accuracy of a sampling result is improved. Moreover, different types of sensor indexes can be alarmed in time through the color indicating lamps and the voice broadcaster, sothat a worker can check wh
