Abstract:

Comparative analysis was carried out on yield and benefits of mechanical transplanted, hand-transplanted and direct seeding of indica-japonica hybrid rice Yongyou 538. The results showed that the yield of mechanical transplanted was highest, followed by hand-transplanted and direct seedling, but the yield all exceed 750 kg/667 m2. From the point of view of cost, the cost of direct seeding was the lowest, it is suitable for small family planting. Because of low seed dosage, low seed cost and convenient management, hand-transplanted was also a good choice for small family planting. However, the machine-transplanted cultivation technique was the best choice for large farming, because the shortage of labor and seasonal needs.
