Compared with manual transplanting, it saves seeds, labor, and seedling fields; it has high transplanting efficiency and low labor intensity, which can effectively shorten the rice transplanting cycle and is conducive to early planting and fast growth; rice seedlings are transplanted with light planting injuries, fast seedlings, more low-position tillers, more ears, and higher and more stable yields. The disadvantages are uneven growth of seedlings, uneven distribution in the field, small ear shape, shallow rooting, and easy lodging. Generally, it has a more obvious yield-increasing effect in areas with more fields and fewer people, extensive cultivation and management, or tight crop connection seasons and late transplanting periods.
