In 2015,the cotton precise seeding and its light simplified management technology in hardened groud was demonstrated about 80 hm2 in Jiangzhou town of Jiujiang county,Jiangxi Province. Compared with the local conventional cultivation technology of trans- plant seedlings into bowl with nutrition,the new way had some differences with the conventional way: the first,the survival rate of seedling was basically similar,all above 98%; the second,the new technogy could save labor cost about 52. 5 labours per hectare; the third,the seed cotton yield increased 492 kg / hm2by9. 7%; the fourth,it could reduce cost and increase efficiency above 7231. 8 Yuan / hm2. It was a new technology with saving cost and improving efficiency,which would be suitable for application in Jiangxi cotton region.
