Abstract: Hydroponic leafy vegetables production has become an important means to improve labor productivity, reduce production costs, and enhance economic benefits．A trend toward mechanized and automated production in development has become inevitable．An autonomous walking pipeline hydroponic system was designed and developed that could automatically adjust growth density according to different plants' growth periods．By making reasonable use of cultivation space, efficient planting was achieved, addressing problems such as excessive human intervention, high labor intensity, and low operational efficiency in hydroponic leafy vegetables production process were solved．
