in 1898, Japan issued the first patent of rice transplanter; Italy began to study the rice transplanter for pulling out seedlings in 1915
till 195s, there were some products for tractors, but they were not popularized because of the complicated structure, high cost and the need for more auxiliary labor
.
in 196s, Japan developed the planting technology of small seedlings with soil and the corresponding rice transplanter.
after p>1966, the factory rice seedling raising equipment was successfully developed, which promoted the rapid development of transplanting mechanization. ?
