Rice Transplanter: Rice Planting Machine - YouTube
A rice transplanter is a specialized transplanter fitted to transplant rice seedlings onto paddy field. Although rice is grown in areas other than Asia, rice transplanters are used mainly in East, Southeast, and South Asia. This is because rice can be grown without transplanting, by simply sowing seeds on field, and farmers outside Asia prefer this fuss-free way at the expense of reduced yield.
A common rice transplanter comprises: a seedling tray like a shed roof on which mat type rice nursery is set; a seedling tray shifter that shifts the seedling tray like a carriage of typewriters; and plural pickup forks that pick up a seedling from mat type nursery on the seedling tray and put the seedling into the earth, as if the seedling were taken between human fingers.
Machine transplanting using rice transplanters requires considerably less time and labor than manual transplanting. It increases the approximate area that a person can plant from 700 to 10,000 square metres per day.
However, rice transplanters are considerably expensive for almost all Asian small-hold farmers. Rice transplanters are popular in industrialized countries where labor cost is high, for example in South Korea.
Rice transplanters were first developed in Japan in 1960s, whereas the earliest attempt to mechanize rice transplanting dates back to late 19th century. [1] In Japan, development and spread of rice transplanters progressed rapidly during 1970s and 1980s.
Mechanical Transplanting of Rice is the process of transplanting specifically raised seedling of rice as a mat (mat type nursery) using a self-propelled mechanical rice transplanter at pre-determined and desired spacing.
The mechanical rice transplanter is fitted with a tin based tray like a roof top on which mat type nurseries are placed during the operation. One manual labour transplants approximately 500 square meters in one day whereas with self-propelled rice transplanter one can transplant 4 acres in a day.
Advantages • Efficient use of resources by saving on labour (20 man-days ha-1), cost saving (Rs 1500 ha-1), water saving up to 10% • Timely transplanting of seedlings of optimal age (20 days) • Ensures uniform spacing and optimum plant density (30 -35 hills/m2 with 2-3 seedlings/hills) • Higher productivity (0.5 to 0.7 t ha-1) compared to traditional methods • Less transplanting shock, early vigour of seedling, better tillering and uniform maturity of crop that facilitate timely harvest and reduce harvest losses • Less incidence of 'Bakanae' disease due to less root injury • Promotes double no-till in rice-wheat system and in-turn long-term system sustainability • Improving soil health through eliminating puddling • Reduces stress, drudgery and health risks of farm labourers • Generates employment and alternate sources of income for rural youth through custom services on nursery raising and mechanical transplanting
