Research on Key Techniques for High Yield through Mechanical Transplanting in Rice Planting Region

The test studied the special fertilizer for mechanical transplanting,sowing amount,date of planting and transplanting and Nitrogen fertilization,the results indicated that the yield can achieve 650 kg/667 m2 by using mechanical transplanting,it can get sturdy seedling for mechanical transplanting which used seedlings matrix and special fertilizer,the sowing amount of conventional japonica rice varieties were 100～120 g/plate for dry seed or 120～150 g/plate for wet seed,normal amount of fertilizer and suitable seedling age from 18 to 20 d.When the transplanting density was 18 000 hills/667 m2 and the basal seedling density on bed is 60 000,date of planting and transplanting was from June 10 to June 20,the ratio of nitrogen fertilization was 6:4,it would be good for full panicles to get high yield.
