Abstract: In the sourth of shanxi, after harvest of wheat, transplanting cotton can obtain lint cotton 904. 5-1266.0 kg/ha, generally obtain 1050 kg or so, lint cotton yield can be increased by over 375.0 kg/ha, compared with that of direct seeding. The machanism of increasing yield for transplanting is mainly to get accumulated temperature 1000-1300 ℃ on seed beds besides in the fields, which could efe out the accumulated temperature and the growth stage of the seeding cotton after harvest of wheat. The engineering culture technics is a set of comprehensive technics i. e. to make plant balls with machine, mechanically transplant, set two plants/hill, use good variety and enhance early maturity.

Key words: The cotton after harvest of wheat, Seedling and transplant, Engineering culture
