with the continuous development of agricultural technology, the planting technology of agricultural products is greatly improved, and with the rapid development of agricultural product planting technology, the technology for planting the same variety of agricultural products in different areas is different, so that how to effectively interact the agricultural product planting technology in different areas is more and more important.

At present, agricultural product growers based on different regions usually identify corresponding growth characteristic data and send the identified growth characteristic data to users with corresponding requirements so as to achieve the effect of data interaction of agricultural products.

Specifically, the processor 50 may refer to the description of the relevant steps in the embodiment corresponding to fig. 2 for a specific implementation method of the computer program, which is not described herein again.

Further, the electronic device integrated module/unit, if implemented in the form of a software functional unit and sold or used as a separate product, may be stored in a non-volatile computer-readable storage medium. The computer readable storage medium may be volatile or non-volatile. For example, the computer-readable medium may include: any entity or device capable of carrying said computer program code, recording medium, U-disk, removable hard disk, magnetic disk, optical disk, computer Memory, Read-Only Memory (ROM).
