Currently, the closest prior art: in scientific research activities such as corn breeding and cultivation experiments, seeding is an initial link for developing scientific research topics. Through the link, the seedlings are complete, aligned and strong, which is the basis for success of scientific research topics, and the quality of the seedlings directly influences the quality of the whole scientific research test by more than 70%. At present, most of the scientific research units adopt manual seeding in the corn seeding link, except that a few of larger scientific research units and species companies are equipped with foreign advanced cell precision seeding. The common method is that the machine revolves the ground and then ditches at equal intervals, a seeding rod or a plant spacing rope is used for determining the plant spacing, soil is covered after manual dibbling or a simple dibbling gun is used for manual dibbling, and then head water is poured. Due to the fact that the quality of sowing workers is uneven and the responsibility is not strong, the number of sowed seedlings is not enough, the sowing distance is difficult to carry out according to the requirement, and the density is not uniform; the manual earthing is not uniform, so that the sowing depth is different; when the watering amount is too large, shallow seeds are washed away, so that the uniformity of the seeding density is influenced; the seedlings emerge unevenly, the seeding in the observation channels of the plot is uneven, and the quality of the scientific research test is seriously influenced.
