PROBLEM TO BE SOLVED: To spread a net and simultaneously disperse and dispose bulbs evenly on a field surface.SOLUTION: In a bulb planting method, a lower net 12 and an upper net 14 are superimposed with each other and retain, in a holding manner, bulbs k fed out sequentially, the upper/lower nets 12, 14 are spread on a field surface predeterminedly, and simultaneously the bulbs k are evenly dispersed on the field face. A bulb planting machine includes in a planting machine body 6: a receiving hopper 3 for bulbs k a first net roller 13 feeding out the lower net 12 and a second net roller 15 feeding out the upper net 14 and a planting roller 8. The lower net 12 and upper net 14 fed out are superimposed with each other, thereby bulbs k fed out sequentially from the receiving hopper are retained in a holding manner, and the upper net and lower net 12, 14 are spread on a field surface with the planting roller 8.SELECTED DRAWING: Figure 2
