AI Technical Summary

Problems solved by technology

[0003] In some remote places, due to unreasonable fertilization and planting techniques, the land is hardened and the yield of food crops decreases. Due to insufficient knowledge, the ecological environment of the land is further deteriorated, making the soil even more unsuitable for planting crops, and these problems are all due to the lack of basic agricultural knowledge, it is very necessary to teach and train planting practitioners

[0004] However, since agricultural training lectures generally rely on local actual conditions for customized programs, they are often given in the fields, and the equipment used for presentations needs to be portable and easy to use. Therefore, we propose an agricultural farming propaganda Demonstration device with portable data projection
